Bassman/JTM45 ExpressSCH

[glassesnvests]

So a customer requested a Bassman AA864, but had heard that there was a mod out there to change the Bass channel to a JTM45 flavored setting. Found an altered BF Bassman schem that had the JTM mods, supposedly: (http://s101.photobucket.com/user/chocopower/media/BASSMANHYPERON.gif.html)
so I redrew it into ExpressSCH in case anyone wanted it, I couldn't find any like it online.

Please double check me! And I've got some questions...

The customer wants:
1. Power Scaling/Master Volume
-and-
2. An Effects loop. ( I mentioned to him that it was probably unnecessary, but he insists)


1) Are there any schems out there for a fixed bias power scale? Or does Mr. O'Connor have an utter monopoly on these?
2) What are some good FX circuits that I could drop in? Should I spring for buffered or unbuffered? Series or parallel?

An help appreciated!

Updated.
Tweaked some values in the JTM45 channel to make it more... JTM45ish.


Added Master Volume (thought about making it switachable bewteen the PPIMV and the voltage scaler?)


Comments appreciated.
