[Longo]

Hello everyone, this is my first post here
I bought this Marshall JCM800 today with .Be / Hbe sat, fat, c45 and solo bost, all fooswichable ..
But I have a question ..
inside, next to the output tranny is a pot for the "Control bias mod"
Someone can explain what is?
Thanks

That doesn't look like Dave's work.

Was this on sale in Germany? I saw it on Ebay and on HRI.

Agreed... looks 'wrong' for Dave's work. Hope Im wrong but I haven't seen a 'solo' boost feature and/or footswitchable in Daves mods.. labeling looks wrong, etc. Hoping OP got a legit Friedman but just doesn't look like one to me.

It's not me. Some one copied the circuit with all the wrong parts. Already been in contact about this amp.
