    Hello there,

    just servicing and refurbing my old TRB 6 (which is the same as the TRB JP1) as something has gone awry with the circuitry. I need the service manual for this model or close up pics of the circuitry so I can replace parts correctly.

    I looked around on the web but thus far to no avail, hence I am turning to fellow bass heads on this forum ;)
    Can any of you guys help with service manual or detailed pics of the circuit? :help:

    Thanks in advance:bassist:
