In this video I max out the gain on a 1976 Marshall Super Lead modded by Daniel Forsberg. This mod squeezes an insane amount of gain out of the Super Lead without adding any additional tubes or diodes. And with a waxed pickup it's relatively robust against microphonic feedback as well. I'm combining two classic 1980s speakers. Probably the two vintage sounding speakers that takes high gain best: Celestion V30 and G12-80 (Classic Lead is the modern name for this speaker)
