I doubt it's going to be particularly helpful, but the owner, Mark, posts on this forum - www.theguitargrounds.co.uk Maybe try him there?

I saw the start of the set on Monday, unfortunatly it was a social and we were hopping between bars so I didn't see more than 40 minutes or so, but what I saw was really good! Definitely going to head down another Monday and watch the full set.

[quote name='derrenleepoole' post='1359687' date='Sep 2 2011, 11:40 AM']Yes, but the guy wanted simple, layman's terms. You're clearly way more capable than me at grasping the full mathematics of what is required, but not everyone needs that. Start simple for now, get more complicated as your experience improves. Laying on a full barrage of mathematics is likely to be more confusing than helpful - even though it is helpful [/quote] You're right! I edited out the equation bit pretty much straight after posting because I realised the OP wasn't mixing 8 ohm and 4 ohm cabs anyway, it was irrelevant. [quote name='Mr. Foxen' post='1361341' date='Sep 3 2011, 09:23 PM']Mileage. The impedance thing is more importantto differentiate it from resistance. And cabs is nominal impedance anyway, so isn't really impedance, 'ohmage' is probably better thought of as a term meaning 'nominal impedance as applied to speakers'.[/quote] This is one thing I never understood, whats the difference between impedance and resistance? From all the definitions of impedance it sounds like it's exactly the same as resistance to me. EDIT: Actually, I think I get it now. Essentially for a DC circuit they're identical in every way, but for AC the impedance takes into account the phase difference between the current and potential difference?

[quote name='51m0n' post='1359654' date='Sep 2 2011, 11:20 AM']Typically (as in , the industry standard complied with by all cabs and amps I've ever seen or used) any multiple socket array of outputs/inputs to/from speakers are wired in parallel not series. This is very important. So it makes no diff to the circuit wether you use the two outs on the back of the amp, one to each cab, or the two outs on one of the cabs to daisy chain. The resulting circuit you've built is the same, two speakers wired in parallel to the amp. In order to work out the total impedance in a parallel circuit the formula is as follows:- 1/total = 1/speakerA + 1/speakerB + 1/SpeakerC..... through all the speakers stated impedances. In the case of 2 8 ohm cabs in parallele weget:- 1/Total = 1/8 + 1/8 = 2/8 = 1/4 so Total= 4 Ohms. That 4 ohms is the total load across the amp, if it is rated to 4 ohms it is a happy amp at this point. Things get complex when you have differently rated impedances on the speakers though, since the lower impedance speaker will get more current than the higher impedance speaker. Simplest rule of thumb is to stick with the same impedance cabs for now![/quote] What he said! And FWIW if they [i]were[/i] in series just add them all up. But like 51m0n says, they'll almost definitely be in parallel.

Ok, so I've completely rewired it as in the Seymour Duncan diagram. Still the same problem. Any more ideas?

Chances are I won't be able to make it this time, I'm going to Uni in September!

[quote name='KiOgon' post='1343275' date='Aug 17 2011, 03:38 PM']Top - standard diagram is correct - 2nd, how you've got it is wrong. The l/h tag of the tone pot shouldn't be soldered to the body, neither should the r/h. Rewire following the top circuit & it'll be fine![/quote] I wonder why it was originally wired like that then? I mean, I may have accidentally done a wire wrong, but it's not like I can accidentally bend a pin on the pot and solder it to the body! Surely there must be a way to do it without changing too much, it worked before!

[quote name='KiOgon' post='1343258' date='Aug 17 2011, 03:26 PM']Show us how you've wired it with a picture can you? The only thing I can think of is that the centre tab of the tone pot, where the capacitor is connected - is also shorted to earth - ie: the pot body. Do you have a multimeter? Cheerz, John[/quote] Wiring diagrams added It doesn't look the the centre tab has been shorted, it's not making any contact with the pot body. It could be to do with the way the capacitor is wired to the volume pot though maybe? And I doubt we have a multimeter, I can check with my Dad when we get home, but neither of my parents know much about electronics, and they're not likely to do any themselves, so I doubt it.

Ok, just for a bit more information, this is Seymour Duncan's wiring diagram. [attachment=87282:Original_Wiring.png] Here's how the bass is wired as I type, and I'm pretty sure that's how it was originally wired. I don't think I've changed anything! [attachment=87283:Changed_Wiring.jpg] Sorry that it's been done quickly on paint, but you get the gist. Also, the capacitor in the bass says 1H (no idea what that means) then 104K, which if I remember my AS level Electronics right means it's 0.1 microFarads, rather than the 0.5 on the diagram. Also the pin on the left of the tone pot has been bent back and soldered onto the pot itself, like the one on the right of the volume pot.

Hi everyone, So I swapped the pickup on my Dad's '51 RI Precision for one of the Seymour Duncan Bassline SCPB pickups. The way it was wired before didn't really resemble the wiring diagram given by Seymour Duncan, so I simply replaced the black and white wires from the original pickup with the black and white wires from the new pickup. Now, for some reason I can't quite figure out, when the tone is rolled off there's a fairly large volume drop. Any ideas? If anyone needs any more information just ask! Thanks, Luke.

[quote name='jumbo' post='1339769' date='Aug 14 2011, 04:59 PM']Hi All. I'm hoping someone can help me out here. I'm seriously thinking about buying a Mexican Jazz. However the advert states that it has a scratchplate that houses all the electrics and controls all in one. I'm assuming this means it doesn't have the chrome control plate. I've never seen one like this before so I'm hoping someone here can let me know if this sounds a bit suss or if they did in fact produce a model like this? Many Thanks David[/quote] If I remember rightly they did produce a model with a one piece pickguard a while ago. I can't remember much about it, in fact I thought it was squier, but maybe it was Fender Mexico! If you want an idea what they look like the Mark Hoppus model they make now also has a one piece pickguard. EDIT: Oh wait, on this talkbass link there's one - [url="http://www.talkbass.com/forum/f8/fender-jazz-bass-83-fullerton-era-746471/"]http://www.talkbass.com/forum/f8/fender-ja...ton-era-746471/[/url] Just scroll down a little.

I can actually be quite fussy over neck profiles, I've definitely sold basses in the past because I dislike the necks on them. I own two basses with Precision necks, and an Ibanez SR500, and I really like them both, even though they're on opposite ends of the scale. I don't like Jazz bass necks, weirdly.

[quote name='xgsjx' post='1290950' date='Jul 3 2011, 12:54 PM']Another option to look at is the Ibanez SR basses, they're pretty light (compared to a good few other basses I've played anyway) & have a huge range of tones.[/quote] +1 for the Ibanez Soundgears, very light basses! And very versatile, too!

I usually think of "standard" basses as having four or five strings, any more is an ERB to me!

[quote name='mrtcat' post='1283349' date='Jun 26 2011, 08:50 PM']Maybe it's just me but do the normal folk out there not appreciate good basslines? I've watched most of Glastonbury this weekend as our drummer is ill and gigs have been cancelled. I have been pretty uninspired by the bass players in the bands that are known as bands but have seen some great bass playing with the solo artists. For example I think Coldplay, Biffy, U2, elbow et all were very average but I loved the playing behind Jessie J, Tinnie Tempa (hate his music and found the bbc coverage frustrating as every other sentence was muted due to swearing), Paulo Nutini, Plan B etc. The exception was Mumford & Sons as I really enjoyed his bass playing. It might just be me tho[/quote] +1, although to be fair, I don't really like Coldplay, Biffy Clyro, U2, or Elbow, but I love Jessie J and Plan B! I like that Ed Sheeran bloke that was on after Plan B, never heard of him until The A Team was released a couple of weeks ago, but I really like pretty much everything I've heard him play since then!

I'm suprised Plan B's bass player is using a pick. He's playing She Said at the moment, it would never have occured to me to play that with a pick!

[quote name='Musicman20' post='1281113' date='Jun 24 2011, 03:17 PM']I dont really like black at all unless I have to. Jon should make a White/rosewood/tort version [/quote] You mean like the [url="http://www.shukerguitars.co.uk/pbassgal.htm"]Simon Rix signature bass[/url]? I bet John would make a white JJB if you asked him to.

Out of all the one's on GAK, personally I think I'd go for this - [url="http://www.gak.co.uk/en/squier-vintage-modified-jaguar-bass-special-black/44284"]Squier Jaguar Bass[/url] (I didn't realise the Jaguar basses were so cheap! That's tempting!) But I'd also definitely check the for sale forum on here and ebay, they'd be my first stop.

I'm pretty doubtful there's any tonal advantage to a single cut. I think most look ridiculous anyway, although some look great (I really like Jon Shuker's singlecut shape). Also it depends what you class as a single cut. Telecaster? Les Paul? Very popular single cuts. But yeah, I think it's just a matter of looks, and I guess they're a little more interesting than a Precision bass.

Wow! This looks great! I've got an Ibanez SR500 with it's paint all chipped and scratches all over it, you're tempting me to do something similar now! Mine's got a mahogany body though, the grain would be nowhere near as nice as yours!

I don't hate them, and they're a bit different. They're not great looking though. I quite fancy playing both, just to see what they're like. I can imagine myself really liking the Precision, and kind of liking the jazz, but never using the bridge pickup, which makes it pointless when I've already got a Mark Hoppus Jazz.

[quote name='Linus27' post='1260714' date='Jun 8 2011, 08:37 AM']Yes, that is exactly what I'm after but fretless [/quote] And this is active, you said you wanted passive. Could be a nice project, and a hell of a lot cheaper than going custom! But then, probably not as nice a final bass as if you went custom.

You could make a project out of one of these? [url="http://squierguitars.com/products/search.php?partno=0300574506"]Squier Deluxe Jazz[/url]

From the pictures on google images, it looks a bit big for a Strat body to me. And like Skank says, why would they use a Strat body then put things like the lower horn contours onto it and "modify the neck socket", rather than just cut a new body?
