I love the prince albert for a great and unique clean tone, the marble drive is really good used as a preamp. The tweedman and deive 55 have a few shades of tweed cleans and means.
It will play clean if you turn the GAIN and JUICE down. Any overdrive pedal you put in front of an amp has a volume control right? How you set that volume control determines whether the preamp gets overdriven or not, just like with a tube amp.
