Title: Amp Question
Post by: Ziggy on July 22, 2020, 09:31:56 pm

Just curious, is a Fuch's Blackjack 21 amp basically using similar AB763 circuits? Saw some videos using this amp, had some great tone.

My understanding is that its two gain stages so probably not AB763. From other sources and the manual it looks more in line with a marshall plexi given the dumble treatment.
