YAMAHA TRB CLUB

#1,642
Hello everyone!!!

I've just posted in a very old thread about a problem I'm having with my MIK 1005.

I've recently bought a 2004 MIK TRB 1005 that I'm currently in love with, but since yesterday, I'm getting the same weird noise. I swapped the battery for a brand new one and even tried a rechargeable one, but as soon as I plugged the bass in, for about one minute, I get no sound at all... Nothing. And then, for another minute, I get that same weird sound the OP got. After another minute, it's gone, and everything gets back to normal.

Does anyone have any clue? I'm guessing it's not really the battery, like the OP, but maybe a problem with the preamp.

Any help is appreciated...

100% these basses are not designed to work with rechargables. They will whine as if they had a dying battery with many (not all) rechargeable batteries.

Check the jack for a short. The barrel jacks on these can wear out much faster than regular frame jacks... I had to replace mine with a Switchcraft and it has not caused problems since.

Thanks!!

Yes, the guy who sold me the bass replaced the jack with a brand-new one, but I don't think it's a Switchcraft jack. Gonna check that.

I put back the regular battery (not rechargeable), and the problem persists. I have a gig tomorrow and I'll use another bass.

Has anyone else had the same weird noise problem and fixed it in a different way? Would it be a damaged capacitor in the preamp?

For you who want to replace the original preamp on Yamaha TRB 1005 Korea, check this video and let us know which one you love most. The OBP 3 SK with the mid switch gives you more control on the mid section. For me I put back the original preamp and I love it more than the OBP. The pick up is original.
What the difference can you hear here?

Hi! Great playing! Already subscribed to your channel!

Would you mind sharing why you went back to the original preamp? I was considering the Aguilar preamp, especially to have a passive tone control and be able to use it in passive mode, if possible. Do you (or anyone else) have any insights on that? Is it possible to run these pickups in a "passive mode"?

In other circuits this type of behaviour can be associated with a damaged component which has a crack or similar defect in it. The circuit is open until the device heats sufficiently that the crack closes due to thermal expansion and the circuit is operative again. It’s hard to think that a low current instrument preamp would do this, but it does explain what you’re experiencing. As a test, let the instrument run for a while then unplug the bass and plug it right back in (while it remains as warm as it’s going to get). If it works fine, it could be something akin to what I’ve suggested here. BTW, it’s hard to imagine a faulty barrel jack connection giving the time-dependent problem you’re seeing. Just wiggle the inserted/seated cable plug to see if the signal cuts out; if so, the you’ve got a bad jack.

Put this gem up for grabs!

SALE! 1st Gen MIJ Yamaha TRB-4 (under 8 lbs)

For sale SALE! 1st Gen MIJ Yamaha TRB-4 (under 8 lbs)

Unusually lightweight, 1st generation TRB. These are highly coveted and sought after. The 3-piece neck is perfectly straight, action VERY low and plays amazing. These are well known for amazing tone and this one is no exception. Fat tone, but somehow also cuts through the mix w/o sounding...

Hello everyone. I was checking to see if anyone has experience with the Yamaha trb5 fretless bass. I think it came out in The mid late 90’s and has a slap cut body.

In all of the pictures I’ve seen, the finish seems to be a very light vs the high gloss finish from a lot of trb’s I’ve seen.

I was wondering if anyone can tell me if there is any difference in tone or quality. Mainly checking to see if anyone can give me their impression on bass.

Thank you!

That's because, at the time, that finish with darkened grain and lifted texture was an in-thing. Yamaha made quite a few TRBs with that kind of finish. It's still durable, and most I've seen have aged similar to the really thick "candy-coated" ones they made. By then they had settled on the three-band B/M/T control instead of the unique midrange selector with bass and treble, so it works more like a typical 3-band EQ. Very good sound quality, with lots of different sounds depending on the dial positions.
