There are 2 different ways to attach to an angle grinder, one is the plain 22mm bore and the other is a 16mm thread that goes in place of the locking nut, usually used for wire brush attachments, https://www.toolstation.com/abracs-twist-knot-wheel-brush/p67421?store=RP&utm_source=googleshopping&utm_medium=feed&utm_campaign=googleshoppingfeed&gclid=Cj0KCQjw2PP1BRCiARIsAEqv-pSHXBJ2ZAGmxp7BhVOD6lM8RXk39L_tjJkDi9lCuovJrL8GedqYLEsaAmBCEALw_wcB I'd imagine that the ones you are looking at are the screw on type as I have never seen an angle grinder with a 16mm plain bore. Matt

I had this dilemma when I rewired a les paul guitar, I don't like 2 volumes so went for one vol and one tone, I put a coil tap switch on one hole and a bullet in the other, a Winchester 38 special fitted nicely with a bit of tape on the inside of the cavity to hold it snugly

I played one of these a little while ago in a shop in Newcastle, they are really very nice, I wss very tempted but was in a 5 string phase so passed (I wish I hadn't!)

you might find that the +2 and -2 connections are already connected across to the +1 and -1 connections, it is hard to tell without seeing the underside of the board, they might not be connected to anything at all (just there to help stabilise the connection or because the same board is used in a few different amps Matt

which version of the speakon do you have as there are 2 different ones, i believe that the -H variant should be the right one, unfortunately many of the pictures online show the -V version which sounds like the one you have as a spare -V version and the -H Version Matt Edit - i've just had another look at the Neutrik website and they seem to be using the same photo for both versions of the socket so the legs aren't shown unless you open the Pdf drawings! and every retail website has simply copied the image from the Neutrik website to further confuse the issue.

i've got a similar setup, using a pair of JPW Minims and a class T amp, not the flattest sounding speakers but i am very familiar with them now and most of the time it's just me listening to music rather than mixing, i have a graphic eq that i switch in for listening purposes and a second set of really nasty speakers ( from a £10 5.1 surround set) that i use for double checking the mix similar to the little auratone speakers used in big studios. Matt

The dimensions of the connectors are identical in every respect except for the extra 2 poles on the 4 pole socket so it should fit exactly into the existing space, I would expect that the tolerances will be very good so the fit will be identical. The chassis mount designation is just because it screws onto the chassis as well as mounting to the pcb, if you look at the technical drawing then you will see that it is almost identical to the one you have fitted already, Matt

Neutrik only make 2 versions of the combo socket, both have a 2 pole designation but unlike other 2 pole sockets they are compatible with both 2 and 4 pole plugs (as per the 4 pole sockets) i would expect that the 4 pole socket is used here as it is the most versatile of the SpeakON compatible ones and probably the most common one in use. the connections will be +1, -1, +2, -2 and i would expect that the +2 and -2 connections are either connected directly to the respective 1 connections or just soldered to isolated pads on the PCB, if that it the case then the 2 pole SpeakON socket will be a direct replacement. is there a model number on the socket currently fitted? the solder tab dimensions could be compared to the available combo socket to see if it lines up (the overall housing dimensions will be the same as they are a common size) as a guess it is a NL4MD-H-1 so the +1 and -1 connections are in the same position so it will connect straight in. https://www.neutrik.com/en/product/nlj2md-h did you get a photo of the underside of the PCB? this would tell you what the connections are to the pins. Apologies if you already know most of this, i included it for others who might stumble across this post in the future trying to do something similar. Matt

i probably should have phrased it better, i know they are copies and not legit (they don't look right at even first glance), but that doesn't mean that they are total garbage for a tenner (but they probably are) i'm still tempted to buy one to see how bad (or not) they are, i need a basic preamp for an experiment and these would make an ok preamp donor for a test before i shell out for something quality. if they turn out to be vaguely usable then it would do for a stopgap system whilst a better quality item was sourced. Matt

the cheap fishman ones certainly don't look Legit although there is a cheap OEM fishman that looks identical (the sonitone) and it is available through more reliable channels https://www.dv247.com/en_GB/GBP/Fishman-Sonitone-Undersaddle-Pickup/art-GIT0033735-000?campaign=GShopping/UK&ProgramUUID=HADAqJarPzAAAAFlea9yjI.G&gclid=Cj0KCQjwka_1BRCPARIsAMlUmEpNkbLoHTiCVVRMBdQ7JFCIP8Pk9YKTV3wYa7m3oh34vbRfRsZt2coaAhfOEALw_wcB the Sonitone may be the cheapest of the Fishman offerings but it is fitted as standard to some big name instruments, even Gibson and Martin use this Pickup/preamp in their entry level acoustics. https://www.pmtonline.co.uk/gibson-g-45-studio-antique-natural-electro-acoustic-guitar?utm_source=google&utm_medium=shopping&gclid=Cj0KCQjwka_1BRCPARIsAMlUmEoaTZSo625zyOEzM4VW1UM5H-FxgPntJnX0Ra5ehsdtjR-LlPQu-JMaAm7FEALw_wcB#product-details i have been debating buying one of the stupidly cheap ebay ones though as an experiment, it might not be proper Fishman quality but it might not be total junk and for under 12 quid i don't have a lot to lose. Matt

@prowla have you managed to get any further on this? i have been debating doing something similar myself if i can find a suitable donor instrument. i was thinking of 4ths/guitar tuning and maybe 5 pairs of strings if the neck is wide enough, what are your plans for the bridge/tailpiece? i was thinking maybe a simple wooden floating type bridge (possibly pinned down) and a wooden tailpiece with pins for the string ends (loop end strings?) and a decorative cover to neaten it up. this might happen if i win the guitar i'm watching on ebay right now. Matt Edit - just had a better look at the picture, can see that you are using a bass bridge, and that it's pretty much ready to go, how is it sounding?

i would suggest that one of the endpin or soundhole preamps would be the easiest and least destructive to fit, my main acoustic has the AER AK-15 which is a soundhole preamp with an undersaddle piezo and a mic, it's not cheap though. Artec make some soundhole preamp options, http://www.artecsound.com/acou/shp.htm there are some Fishman ones on ebay but i don't know if they are Legit Fishman or copies as they are so cheap . Like this one https://www.ebay.co.uk/itm/New-Fishman-Acoustic-Guitar-Pickup-System-Fishman-VT1-Tail-Nail-Pickup-EQ-DIY-UK/264420760972?hash=item3d90b49d8c:g:2EkAAOSw3O5dSASd I have aversions to cutting holes in acoustic guitars to fit preamps (although my dreadnought is a factory electro with a side mounted preamp and battery) my blues guitar has one of the Basic Fishman soundhole magnetic pickups wired straight out to an endpin jack, this is for blues playing though so i wanted that particular sound Matt

these are the acoustics From Left to right - McIlroy AS25, bought exactly 12 years ago today, Handbuilt cedar/walnut acoustic, retrofitted with an AER Pickup/mic system. the best acoustic i have ever played, all solid woods and just the most glorious sounding guitar, quite folky sounding but just an all round wonderful instrument strung up with Newtone Heritage 12's which are the only strings i will use on this guitar. this is the most expensive instrument i have ever bought and on the day i bought it the most money i had ever paid for a single item but one of the best purchases i have ever made. Yamaha DW105c my first acoustic, has a pickup/preamp and a solid spruce top, currently fitted with nashville strings and tuned a whole step low (d-d) for use with my band. Gretsch Jim Dandy, 24" scale all laminate small body guitar, bought to get a good bluesy sound for playing in the band, it's got 13's on it and is tuned d-d to compensate, this is a great bluesy sounding guitar and was really cheap from a local facebook group. Matt

I started out as a guitarist so i've got a few, these are the electrics the Tele is a mex one, i've done a 4 way switch conversion and recently swapped out the scratchplate for a black one, it's a great guitar, i stupidly sold it to a friend a few years ago but bought it back last year, the Les Paul was bought mildly butchered and now has Seymour Duncan pickups (JB and a Jazz) and a V/T/Split setup as i'm not a fan of 2 volumes on a guitar. Next is a custom Superstrat made by Paul Richardson, i bought it very cheap secondhand, it's got an early Floyd rose and a JB Seymour Duncan at the bridge, the body is one piece across the back with a Burr walnut top, it's heavy but sounds glorious, i've had it for nearly 20 years and i'll not part with it. the red Aria superstrat was my first guitar, it's a surprisingly good guitar, quite versatile. the semi is an early Tanglewood, and was bought sight unseen from our guitarists dad (who bought it new) again its a great guitar. I'll see if i can get a pic of my Acoustics together, today is the 12th anniversary of me purchasing my main acoustic guitar so i need to get some playing done today anyway. Matt

Personally I would be wary of a full set of strings that cost the same as a single string from one of the big string makers, places like strings direct have options that start under 20 quid or there was a set of short scale ernie ball slinkys in the marketplace last time I looked. Matt

Thank you @Beer of the Bass and @Pow_22 that seems to be fairly conclusive, the comment about them sounding more modern is a bit of a contradiction to me as this bass has the most classic/vintage sound of anything i have played, it's probably because the strings are so old or possibly because it is an older bass (1977 or thereabouts) I'm going to have to keep an eye on the classifieds for a used set of Ernie ball flatwounds by the sound of it Thank you again. Matt

I've just thought of something else, if you ever decide to sell this or part it out then you might find it more difficult to sell than if it had more "normal" fretwire. Matt

the main thing to check is the width of the tang of the fretwire, i think that most frets are all pretty much the same in the width of the tang, might be worth checking that the slots are deep enough but apart from that the profile of the fretwire are more of a personal preference. one of my favorite basses has almost completely worn out frets, it's pretty much fretless but with a set of flats it's one of the best sounding basses i own (i just wish it didn't weigh so much!) Matt

I would start by checking that power is getting to the preamp, then I'd investigate the jack socket as this is acting as the on-off switch, you should be able to check each of the pots as well, I'd suggest that as soon as you have checked the power it would be sensible to remove the battery and maybe unplug the preamp as it is a sealed unit so it won't be possible to fix anything inside of it, if all the other connections are solid then it will be new preamp time.

make sure it is the right adapter, the sort most uk people take abroad is for plugging a uk plug into a euro socket, you need the opposite, for plugging the euro plug into a uk socket, i wouldn't worry about using an adaptor as that is what thomann supply if they sell you something with a hardwired euro plug. Matt

Hello, do you have a multimeter? It's likely to just be a bad connection somewhere shouldn't be too much work to find the issue (I am a huge fan of aria integra basses, had one of the passive ones as a first bass and have a short scale one sitting next to me right now. They are far better basses than the price tag would have you believe. Matt

i believe that quite a few people have been fitting the uke bass strings to their ashbory basses, they are supposed to be a bit more useable than the originals (and there is quite a range available now) i have thunder reds fitted to my Kala U-bass. (i also have fond memories of the bass place on Nun street, it was part of my weekly trawl round Newcastle, usually just after a browse in Spenders across the road.) Matt

@fleabagas the fans are blowing into the amp you might want to consider a couple of dust filters to help keep it nice and clean (as you have gone to the effort of cleaning it) most computer places sell very cheap magnetic dust filters, i think they are a couple of quid each, might be worth it (or for anyone else with a inward facing fan) https://www.google.com/search?q=magnetic+dust+filter Matt

As there seems to be a fair amount of talk about strings at the moment, and i've got very little else to do i have finally taken some (hopefully) clear photos of the strings on my precision bass. I bought this bass almost 10 years ago and the previous owner had fitted a set of used flats that they found in a cupboard, these most likely came off a bass that they bought then strung up with something else so he has no idea what they are, the gentleman who set up the bass didn't know either. they have a great sound and i have adjusted nothing on this bass since i bought it, it just sounds and feels right so i have left it alone. does anyone have any idea what these strings are? I'd love to be able to fit the same ones to another bass or just to be able to have a spare set if the unthinkable happens and i break a string. Thanks in advance Matt
