Amps that pair well with the Fulltone Fulldrive 2 MOSFET

gain stackingStacks two gain stages for more saturation than either produces alone. (mid-forward → high gain)

Put Friedman Dirty Shirley in front and the mid-forward tone leans further toward high gain

Comes later in the signal chain

fills a frequency gapFills in a frequency range the other side doesn't cover, instead of piling more onto what's already there. (bright → warm)

Marshall Bluesbreaker leans warm right where the bright tone needs it
