Could be, depending of the type of jack used and if it's an active bass... Go see someone with a bit of electronics knowledge in your area : it's an easy fix, but if you don't know what you're doing, it will be a dead end...

Nope. You can do a much cleaner grounding than this by running a single wire from pot to pot and soldering the lug to earth to the pot (just fold it until it touches the pot and do the solder).

Don't you know someone who can just renew them ? It will fix the problem for sure.

If you can use a soldering iron, please renew all the solders. Never seen such a mess. Must have been made by a mad man. The amount and paths of groundings are seriously questionable...

Do a new solder on the earth of the right lug on the J volume and it will certainly work. Did you buy it like that ?

Wash your words. 😁

Turning a machine ? 🤣

Do you mean put a Bart on a Dart ? Ooh spiky ! 😉

That was the one thing I wasn't hearing mentioned. Are you sure it is your bass that doesn't have a good tone? The B string in just below 31hz, even at the point that your ears frequency response is dropping off. You need a hell of an amp speaker combo to be able to accurately transfer that to the same level as the higher frequencies - even speakers renowned for good frequency ranges don't do that well, most of the barefaced cabinets for instance say 'useable range' down to 37Hz and they are one of the few manufacturers with non made up specs Urm, I mentioned it at the beginning of the thread. 😉

I used to own one, not terrific indeed, but those are not Bartolini pickups nor preamp, but designed by Bartolini, so just like the awful pseudo EMG's on Hohner basses, only selling a name, not a product not even made by the brand itself. I was 100% sure that this was it, strangely. Try an American MTD and tell me about the sound, but the lutherie is also top notch quality, which proves what I've always said : an electric instrument is, above all, an acoustic instrument. If it doesn't sound unplugged, it won't do better when plugged. And the Cort Curbow was a deep sh*t unplugged.

Urm, Bartolini tone is just the exact opposite of cold, dull and sterile. I don't know which bass you tried with these pickups nor preamp, but it must have had some serious problems. You are right, it's not about string length, but construction and mastering it.

The 36 inches scale basses are not really standard... I'll maybe be selling my rare Japanese Tune BEB-6 (but it's a 6 strings bass). If you can find a Tune BEB-5, go on, they are terrific basses. Overwater is making some 36 inches scale basses too. Just as Celinder or Fodera do, but in this case, be prepared to sell a kidney. 😉

You're not British, that must be the reason, or you are the only one with good taste. 😁

I love everything about this bass, except the look that makes me want to 🤢 puke 🤮 oops, did it. Terrific players too, but, man, how is it possible to have such bad taste ?

In fact, there are lots of conditional sentences in this "authentication"...

The cheaper is here :

The Seymour Duncan Hot Stack Jazz Bass will make a terrific association.

By the way @Marcoelwray can offer you great prices on Delano and Nordstrand. Ask him for a quote.

Glockenklang (even if I love their preamps) don't work well with Yamaha pickups, strangely. Bartolini is working great with Yamaha pickups, Aguilar too, but it has too much of everything in the end, and the Nordstrand preamps are to me a bit too expensive, but their pickups are terrific and expensive too. Is your TRB-4 the one with the Jazz Bass like pickups (if it's a first generation) ? Maybe you've got a picture.
