I corrected the final wiring of Wolf for those interested.

The Founder of EMG Rob Turner was in Irwins shop during the time Tiger was being built 78/79. Worked with Cutler on Tigers preamp and then went on to continue to make them for Jerry. Like CAE Sound, EMG's JG-1,2 and now PA-2 made improvements on Cutler's original circuit in Tiger. One tad bit of great free info is that the same opamp(tl061) used in the EMG JG2 can be used in a CB-1 and the TPC-1 and has such a decreased battery draw that its playing hours are like ten fold versus the lf356. Don't kill me on the math but it is significant. Jeff Mattson uses them in his buffers.

Anyway, hope this finds who is looking for it.

Thank Mike. What is the correction? Unless I'm missing something the only thing I see that's different from the the old schematic I have of yours is that you specify Dual Sounds vs DP104's. Am I missing something else?

The preamp buffer was not an Alembic Blaster as initially speculated, further study shows it is actually an early EMG JG-1, still ten dB boost..

Thanks for the great info as always, Mike!

Have you done a TPC-1 build with the tl061, and if so does it change the basic sound of the buffer to any significant degree? Is it possible to order one with it?

Not at the TPC-1s gain factor, no significant degree. yes, i have tried this, and yes it can be swapped.
