G&L Rev 1.0 Preamp Treble Boost??

[manoverboard_21]

Can the older G&L 1.0 Preamp run the current treble boost setting on the active/passive switch??

I believe the Rev 1.0 is nearly the same thing as what is done today.

All G&L preamps can be run with treble boost if you switch a resistor into the right part of the circuit. If you have preamp board out of a Climax, L-1500, or L1505 there is one resistor that is different so that it is always at treble boost. There is info up top in the sticky area.

On the G&L site they have a revision 2 preamp schematic. This is what I believe you need for the Rev 1.0 PCB (the early Leo era G&L preamp had no revision on it and is a different beast). The schematic is a bit cryptic and has one error in it. If you need help interrupting this schematic, I can help.

Thanks Dave. I think I have an L2K preamp cause the R7 and R9 resistors are the same. I really just need a simplified wiring diagram. I'm running a Carvin splittable humbucker and I'm gonna hook it up to the Rev 1.0 preamp.
