Discussion in 'Basses [BG]' started by GENERAL SHERMAN, Jul 27, 2003.

  1. I have recently purchased a used Yamaha TRB 6 BASS ( only says TRB on headstock )
    It has Yamaha active pick ups.
    It also has a five knob configuration for adjustments all below the bridge area of the Bass.
    There are 2 larger knobs, one I know is the volume.
    Directly underneath are three smaller knobs.
    I can't find an owners manual on this anywhere, and I am not EXACTLY sure what each knob does.
    Can you offer any help?
  2. treble,mid and bass.

    You got a Yamaha TRB6II they have 5 knobs (Vol/bal./bass/mid/treble), I have that bass (amber burst), nice bass indeed.

    the TRB6PII has 6 potentiometers (one for the piezo) while the old TRB6P has 5 pots(vol/bal/bass/treble/piezo blend) and a piezo toggle switch whitch wasn't mentioned...also there's no YAMAHA on the headstock of the old TRB6P (Yamaha logo/TRB6P)
    here is the logo:D:D

    ps. man, I love my TRB6P:cool::cool:
  6. Thanks to all for all of the quick responses.
    The two upper knobs ( full size ) are definately volume & pick up selector.
    The three smaller ones are from right to left while playing the bass:
    1 - has three positins , but is a non - click position knob. You just feel center.
    2- has three click positions
    3 - has three positins , but is a non - click position knob. You just feel center.
    There is no toggle, so that must mean no piezo I gather.
    On the headstock it only says YAMAHA in smaller letters that run horizonatally across the very top.
    The TRB-6 runs up the headstock between the string winders.
    There is no P or PII.
    I think it is one nice bass.
    I jammed on it for about 5 hours today with some folks who really push the jam, and it feels a bit wide once you get up around the 9th fret, but it is amazing how quick one adapts to the neck.
    In short order you learn to appreciate the six strings and the neck width is not an issue.
    It is one VERY solid sounding instrument.
    By the way the neck is two truss rod & 6 bolt- bolt on.
    Glossy purple, wood grained finish - maple neck, rosewood fingerboard, gold ( brass ) metal.
    On the BACK it has a set of directions for adjusting the on-board electronics,that is on the black cover over the electronics and knobs. High mid - low which I think I will leave alone as the instrument sound great, and I have no clue about the adjustments.
    I have NOT been able to locate any serial # and it is not visible anywhere.
    With that description can anyone give me an approximate date of manufacture, or if there is a serial # wwhere is it, and can I date it by that?
    Thank again for the help.

    this sounds funny, the origional TRB's were neck through i thought. I was sure that TRBII was the bolt on. and since you cant find the serial no, maybe it has a new neck abd is a TBRII or something else... (just a thought)

    The two larger knobs are volume and a pan pot, the three smaller knobs are bass,treble and a three position midrange switch (midrange boost, midrange scoop and flat). Go to Yamaha's website and find info on the new TRB's. I think the specs are about the same.

    Good you have a Yamaha TRB6 (I), the patitucci clone:D. I had two five string versions of that bass (TRB5 and TRB5F-fretless)the fretted one was good but I didn't like the fretless, sold them to a BIG Yamaha fan:D:D
    Read the manuals on the rear cavity cover for adjusting the mid knob (the middle one).
    And the serial number.....
