The first generation TRBs (not the P series) had three position mid switches - flat, EQ1 (which I gather is a mid cut) and EQ2 (which can be set to boost or cut). But I'm finding that I get a volume jump between the flat position and the other two positions.
That seems logic. You change your eq, specifically mid frequencies, the volume changes. It’s normal.
The thing that’s really throwing me is that there’s a jump when I go to the mid cut EQ. Seems like, if anything, it should produce a loss in volume. But it sounds to me like there might be some boosting of bass frequencies, too…

Man I was thinking back to high school
We had a 4 string trb4P
But the teacher I guess had problems or somthing with the instrument. And ripped out the preamp
making it vol vol tone
Just sat there and was a killer instrument
until a local band came to play and borrowed the schools bass and then dropped it on the gym floor

Do you sell the original on bord yamaha preamp? I will pay immediatelyHello everyone!!
Long story short…. What do you see in the picture is my Yamaha trb6 1996, first owner, kept the bass until few years ago and I sold it (regretfully) because few changes in life.
I was looking for a bass during this days….and guess what?? I found it on sale from the same guy that bought it from me, of course I bought it back straight away.
You cannot immagine the smile on my face
Anyway now the bass doesn’t really sound good, and especially with my pedals sounds awful (while my other passive bass sounds really good through them).
I’m thinking to swap the original pickups with the Bartolini g6 candybar as they are a direct replacement, and wire the bass on passive mode like a fender jazz with v-v-t.
Did anyone do that? If yes how it sounds?
Thanks so much and have a nice Christmas!!! View attachment 4514733
Hi everyone!
A friend of mine give me his Yamaha trb6 1 series Made in japan.
Unfortunately the bass has not the original onboard preamp.
I’m searching for an old ORIGINAL 90’ trb on board preAmp.
Please let me know if someone could sell it!
I will pay immediatly.

I'll have a look, 90% is in some box around home. where are you located?
On the topic of TRB preamps… I love the sound of the preamp and pickups on my TRB5PII. I am a little worried some day the 30 year old electronics in the thing may die and these parts are virtually unobtainable these days. What do you guys think would be a modern approximation for the pickups and preamp? I was thinking maybe EMG stuff for the “hi fi” type sound but I don’t know…
with my trb6 I went with bartolini pickups, now in passive mode, but planning to put a bartolini preamp with A/P switch
The electronics will outlast you and I. There isn't much to pickups and preamps to begin with. The main things that go are "user interface" associated - e.g. pots, switches and jacks; basically anything required to interface between the user and the electronics. The preamp will be a PCB with opamps and other solid-state components that will last forever with normal use.
Yamaha [Canada] does a great job of maintaining a library of catalogs, manuals and parts for all their product. I picked up a 1970s-era Yamaha YBA-200 (bass head/cab) a while back and was able to get service manuals complete with schematics and parts lists; everything can be rebuilt from there. The head had a few broken slider pots that were unobtainable (to their credit they did a world-wide search) but I found another head so I could strip one for parts.
The TRB5PII is a great bass and the one at the top of my list. I played one briefly at a NAMM but the $3500 price tag was a bit much then, and I'm sure they're worth even more now that they aren't made anymore.
Enjoy the best bass ever made!
Well that is good to know! I got mine for <1K from someone who had been gifted it and frankly mistreated it, it was a quite banged up and neglected. Plays and sounds great though! It is certainly the nicest bass I have ever played and really cured my GAS for basses...
That's a great price. They were around $1800 for a while used (when you could find them) but once they were discontinued they became unobtainium.
If you have regular humbuckers, and not the special hum-cancelling pickups that need a special out of phase coil, then you can pretty much throw anything in there - even something as simple as a Bartolini buffer.
That aside, my other daily driver has EMG DC pickups and I just love them - especially with a BTC or BQC preamp from EMG - just really a versatile, amazing sounding kit.
I'm not so sure about that. The 5PII has a piezo bridge (that's what the P in 5PII is about) in addition to custom Yamaha magnetics so the an off-the-shelf solution might not work that well.
If the Yamaha magnetics don't need the out of phase amp, then yeah, it'll work. Their regular humbuckers are not anything all that special.
Bart also has a buffer that will tame a piezo bridge, too. You just have to look around for parts. It won't be a single-board thing like the Q series Yamaha board that's in there, but you could definitely piecemeal something together. I could see two buffers (one mag, one piezo) and a TCT working very nicely, but unfortunately my TRB needs the hum-circuit so I'd have to rip out the pickups if I ever needed to move on.
