I just got a used 50w plexi this looks like that it has been modded at some time and it has been made to stay very clean.
I am looking to turn it into a high gain amp any recomendations
Yes the fabled soft-plexi tone.
I heard Joe Pass used to be a BIG closet plexi player. It's also a very little known fact that George Benson recorded his Breezin' album with a 1968 100 watter placed in the studio bathroom.
