Yeah, it's definitely a me problem. Well, me and other south east London bassists.

This pedal sounds like it would be right up my street, soundwise, but the name throws me every time. I can think of few things less rockn'roll than a Waitrose-and-skiing-holidays middle-class enclave in South East London.

The great Canadian luthier Ted Woodford does a lot of headstock break repairs, so his videos would be a good starting point if you want to see what the process of repairing a break like this involves. People with that level of skill don't come cheap, but doing it yourself would involve not just a lot of expensive tools but also the manufacture of a bunch of specialised, carefully measured jigs and guides.

I can't even work out what happened to that Rock bass neck. Was it a crack that someone tried to widen out and fill with a plug or something? The g-clamp-pad shaped dents in the neck suggest someone (you?) has already tried to glue it and clamp it. I'm sorry to say that you only really get one shot at repairs like that. Once you've saturated the pores of the wood around a break with glue there's nothing for a subsequent glue-up to grab onto. If it isn't stable after the first attempt, it's not going to become so with the second. No unless you do some pretty drastic routing.

So, I'm sticking this in here as a sort of footnote on an already much-too-long description, because it's worth explaining a little of the background behind those little string extender thingies you can see in the close up picture. When you're designing a new instrument, there's always something you forget to consider. With this one it was the overall length from the string anchor to the tuning peg. The overall length of this guitar's high-B, from anchor to anchor, is a whopping 990 mm. As it turns out, this is too long for most brands' guitar strings to work (at least with the non-locking tuners I designed it with originally). Ernie Ball strings generally have an overall length of 39 inches (990 mm), d'Addario always aim for "at least a metre", and Rotosound are about the same. Each of those brands have strings they market as being for "baritone guitars", but while these are much heavier gauge (too heavy, I'd argue for most common baritone tunings) they're not actually any longer than normal guitar strings. For the first few years I played this guitar, I used Jim Dunlop strings because for some reason, they're all 46 inches (1160 mm) long. They're not a brand you often see in physical shops though, so I added the little doodads to effectively move the anchor point forward far enough that I could use more easily-available strings. With locking tuners, you don't need anywhere near as much overage at the tuning peg, so I think you could probably take these off and still have a reasonable selection of brands. I also suspect longer strings will become more common now that all the metal boys are playing weird multi-scale things.

Some of you may know that I make basses as a hobby. I also make guitars. Once, as an experiment, I made something in-between. That's right, we've got another baritone guitar on the marketplace. I made this in 2019 when I was experimenting with some ideas for my fretted bass. While it's an interesting thing, plays wonderfully and sounds great, I'm not really enough of a guitarist to need it much. It's just taking up space in the rack. I know "baritone" can mean a lot of different things, but in this case I would say that it's more a big guitar than a small bass (which is why I'm sticking it here, and not in the main marketplace). It's got a scale length of 710 mm (27.95 inches in old money), and is currently tuned B1-E2-A2-D3-F#3-B3 (like a regular guitar, but down a fourth) with a set of 56–11 d'Addario XLs. In terms of vital statistics, it weighs about 4.2 kg (9 lb 4 oz) per my bathroom scales – so heavy for a guitar, but pretty normal for a bass – and it has an overall length of 106.4 cm, which is about the same as a Fender Mustang bass (it lives in a Fender short-scale bass gig bag). The nut width is 43 mm, with the same string-to-string spacing as a stratocaster. The bridge is a tune-o-matic with the saddles filed to match the 9.5 in radius on the fingerboard. The neck profile was copied from my 1970s Ibanez Studio, and is broadly the same as a standard Fender. It measures about 22 mm thick at the first fret (measured with the strings on). The action is pretty low, about 1.2 mm at the 12th fret on the treble side, and 1.4 mm on the bass, with no buzzes, dead frets or rattles anywhere on the neck. It's got the standard two humbuckers (Stewart-MacDonald "Golden Age" PAFs) with a three-way switch, volume and tone, but it also has a coil-split switch that acts on both pickups. I tried various incarnations of active buffer circuits in the quite generously sized control cavity, trying to match the output of the single coils and humbuckers, but none of them sounded that great to my ears, so I've taken it out now. There's no gubbins and no battery in this. This would normally be the point at which I'd mention a few minor quirks and blemishes, and here I'm a little unsure what to say. This is a more-or-less wholly hand-made instrument, assembled on a workbench in the garden of a house in south London – it's been made with care and (if I say so myself) a reasonable amount of skill, but judged by the standards of a CNC'd or master-built instrument, it's mostly blemish. The big things would probably be the finish on the neck, which is slighly discoloured in places, some bumps and divots on the back of the body, and the neck pocket, which I made slightly too deep and then had to shim up with tapered strips of maple. As I mentioned, I have a gig bag for this, but no hard case (not even sure if you could get one that fits), so I'd really rather not attempt to ship it. I'd be happy for potential buyers to come by and give it a play (I've got a Fender Champ clone with a sealed 1x10 cab that does the low end well). (I'm including this to show the Spector-style curve on the body, which was a weight-saving thing).

Shuker Bass build 7 year itch
Mediocre Polymath replied to deepbass5's topic in Repairs and Technical
Nice work. I did a very similar project a year or two ago. I'd made a baritone guitar back in 2018 that played nicely but was insanely heavy (ash, man). Took the whole thing apart and completely reshaped the body to reduce the weight. I don't know about you, but I found taking a big set of rasps and gouges to an instrument I'd already decided was finished to be even more nerve-wracking than building one from scratch. It feels like you're going back to square one. -
Do you know whether the main humbucker is wired in series or parallel? I've played basses with this pickup arrangement ever since I routed a jazz pickup into my OLP musicman copy in 2003, and I've found that they're generally pretty similar so long as the bridge pickup is wired in parallel. The neck is always a bit quieter, but not unusably so.

Little Mark III head - £250 - *WITHDRAWN*
Mediocre Polymath replied to Jakester's topic in Amps and Cabs For Sale
If the yellow-faceplate markbass gear has the same overall design as my LM250 Black line head, then the pots are small sealed units. When they get scratchy and shite, you have to desolder them and put in new ones as they can't really be cleaned. It's a pain, but the preamp board is at least relatively easy to remove. -
I've found myself pondering this as well a few times, because there are a few songs where I'm almost certain the commonly posted lyrics (the ones that come up on Spotify, etc.) are wrong. I believe you do have to copyright lyrics somewhere, as part of that publishing company arrangement that recording artists have. But I think those lyrics are often written down after the fact, either by a singer who doesn't clearly remember exactly what they said on the final take, or by some record company legal intern who is just trying to decipher the recording like everyone else. Also, a difference of a word or two isn't going to change much if a legal challenge is brought, so I don't think those official lyrics have to be entirely correct either, so long as they get the general gist. There are a few examples I've encountered over the years (can't think of any off the top of my head, annoyingly) where the lyrics in the liner notes (an allusion that I've just realised makes me sound old) make sense and are very neat, but don't actually scan. And the actual lyrics sung on the recording have some sort of half-slurred fudge in place of the offending phrase. There's also cases like "Tourettes" off In Utero which I'm certain is just Kurt screaming pure gibberish, despite the song having a full set of lyrics on paper. I think that was just one of those weird sarcastic Kurt jokes.

Bass cab, 1x10, with tweeter. South London ON HOLD
Mediocre Polymath replied to Mediocre Polymath's topic in Completed Items
I'm afraid I have no idea. It was some old sheet stock my wife found tucked away in a corner or her workshop. You can get materials like it relatively easily, but only in 2440 x 1220 sheets -
I've decided I'd rather this went to a good home, or at least a curious tinkerer. Whoever can pick it up soonest. It measures 34 cm wide (including side feet), 45 cm deep, and is 58 cm high (again, including feet). The cabinet is 18 mm birch ply. The speaker is a 10" Eminence Delta (can't remember the exact model) with a power handling of 200W RMS and a frequency response of something like 55–4,000 hz. The main speaker is paired with a 4" B&C midrange driver that's connected through a crossover, and extends the frequency response up to about 10,000 hz. It originally had a compression tweeter, but I quickily decided this to be scratchy and tinny sounding. I've found these two speakers give a decent half-way point between vintage rumble and hi-fi treble. It has connections for 1/4 jacks and Speakon on the backplate, but as the 1/4 jack output on my amp doesn't work, I can only vouch for the speakon. There's also a switch that bypasses the crossover and tweeter. It's covered in luxurious red leatherlette. I've been using it mostly at home for the last decade, but it does go out on gigs every now and then. When driven by my Little Mark 250 head, it has kept up just fine with the drummers I've played with, and it sounds good to my ears. At this point I'm guessing you're shouting "enough about your taste in tweeters, what's the weight?", and that's fair. I have been avoiding the subject. Due to some combination of unusually dense 18 mm ply, an oversize box and an old non-neodymium speaker, this thing is like a tiny rock-n-roll black hole. It weighs just under 20 kg. So yeah, if you're looking for a speaker to sit in a rehearsal space, basement, or shed with a reasonably strong floor, this cab could be just the thing for you. Collection only, obviously, I don't want to even consider how much shipping would cost. I'm based in London SE4 and around most days.

I'm not an informed source on this, but from what I've heard, there seems to be growing consensus among occupational health people that CF and similar resin- or epoxy-based composites are even worse for the human body than previously thought. The kinds of precautions needed to handle them safely, and stay in compliance with the law, are probably easy enough for a massive corporation like Boeing or Airbus to do, but would represent a massive problem for smaller operations like musical instrument gear makers

Moving an item from "For Sale" to "Recycling"

Great thanks. I'll do that shortly -
Moving an item from "For Sale" to "Recycling"
Mediocre Polymath posted a question in Site Issues and Questions
Hello folks. I have a bass cab listed on here that I've decided I'm happy to just give away to whoever is willing to come collect. Is it possible to move stuff, or change the price to £0, or should I create a new thread over in recycling and withdraw the other one? -
NCD! - Home-made portable 1x10
Mediocre Polymath replied to Mediocre Polymath's topic in Amps and Cabs
I'll definitely report back when I've had a chance to properly turn it up. Not sure when that will be though, as both my bands have gone a bit quiet lately. That's actually sorta the reason why I decided to make this thing, in a roundabout way – I've had a bunch of projects fall apart because of difficulties finding rehearsal spaces that everyone can get to without hours of travel. I made this so that I, at least, can be a lot more flexible about where we play. -
NCD! - Home-made portable 1x10
Mediocre Polymath replied to Mediocre Polymath's topic in Amps and Cabs
I'm sure I've seen another bass player with a wheely extendo handle on their amp. I was looking at folding trolleys for a while and then thought I'd simplify things. I'm a little worried that the internals of the extension mechanism might rattle at volume, but it's easy enough to put on and take off with a flat-head screwdriver (it's attached with M6 bolts that connects to blind T-nuts on the inside of the enclosure). -
NCD! - Home-made portable 1x10
Mediocre Polymath replied to Mediocre Polymath's topic in Amps and Cabs
The theatre techie would be my wife, she's been running theatre workshops for long enough that she's on first name terms with everyone there. They've left their old warehouse (the one in Deptford, yes?) and gone out to Dartford now. -
It's finished! Mug for scale. It's 42 cm high, 30 cm wide and 34 cm deep. Weight is 11 kg, though I think about a kilo of that is the weight of the (removable) luggage handle and the heavy-duty flightcase wheels. I don't drive, so my aim was to make a speaker cab that's small enough to be wheeled around like a carry-on suitcase on public transit, and light enough to not cause me grief when going up stairs. I've covered it with some luxurious brown faux-leather (left over from reupholstering some dining chairs), but I'll probably make a weatherproof cover once I've had more practice with my wife's sewing machine. The main speaker is a Faital Pro 10PR320 (300 watts RMS), while the mid-ish tweeter is a Faital Pro 4FE42. It's got a hand-wired 4th order crossover that splits the signal at about 1.8 khz. It sounds really great to my ears, though I admit I'm not the most experienced judge of these things. The response seems pretty even, sounding like a DI'ed bass when everything's set flat on the amp, but it responds well to any adjustments to the eq or pickup balance changes. It's also noticeably louder than my old cab, and reaches "shaking the walls and annoying the neighbors" levels with my amp's gain and volume at about 3 out of 10. Considering I only use a Little Mark 250, and this is an 8 ohm cab, that's impressive, I think. Many thanks to @Bill Fitzmaurice and @Phil Starr for answering questions about the elements of the design I got stuck on, and for generally dispensing wisdom essential to this build in various threads.

Not sure, when I got it it was already about eight years old. I tried various things the clean the neck, but it kept seeping back out.

I used to have a Warwick Corvette Standard from either 2001 or 2002 (don't remember exactly). It had a neck like a baseball bat made from a very open-pored set of, I think, Okvangkol laminates. It also had an oil finish that was always just a little sticky to the touch. Beautiful bass, but yeah, deeply unpleasant to play. I eventually gave up and sold it.

Excellent DB playing (not jazz)
Mediocre Polymath replied to Burns-bass's topic in EUB and Double Bass
If you've enjoyed Billy Strings, I'd suggest the great Paul Kowert of the Punch Brothers and his own band, Hawktail. I think their track "Frog and Toad" is a good example of him in a more relaxed mood. He can play some crazy stuff, often involving him doubling Brittany Haas's fiddle playing up at the dusty end of the fingerboard. This rendition of the Scandinavian folk song Gla låten is a good example. -
EDIT: KNOCKING THE PRICE DOWN TO £50 because I've nearly finished building the replacement cab. This is a 1x10 cabinet that I built for myself a little more than a decade ago. At the time the options for speaker cabinets were more limited than they are now, as were my funds. I wanted a speaker that would fit into a narrow alcove in my house, like the line6 combo I was using at the time, but that didn't sound like total arse, like the line6 combo I was using at the time. It measures 34 cm wide (including side feet), 45 cm deep, and is 58 cm high (again, including feet). The cabinet is 18 mm birch ply. The speaker is a 10" Eminence Delta (can't remember the exact model) with a power handling of 200W RMS and a frequency response of something like 55–4,000 hz. The main speaker is paired with a 4" B&C midrange driver that's connected through a crossover, and extends the frequency response up to about 10,000 hz.

So yeah, if you're looking for a speaker to sit in a rehearsal space, basement, or shed with a reasonably strong floor, this cab could be just the thing for you. If nothing else, the handles (there's one at each end), corners and feet are decent quality and probably worth a few bob. Collection only, obviously, I don't want to even consider how much shipping would cost. I'm based in London SE4 and around most days.
