True, he did say that, but then again, we have a VH4 in the AFX. Not many have seen real Diezel schematics. I have a copy of the schems for the VH4, and it's loaded with pitfalls - omissions, what must be purposeful errors and/or design changes over the years... I can only imagine at least SOME reverse engineering must have taken place with the physical amp present, and on that amp in particular it must have been a monumental pain in the ass.
...but WELL worth it!
Moke is on FIRE today!
I think he said he opened that up a traced all the components. IIRC he stated it is very time consuming.
