I havn't really used it at all lately. Last time I did I was going for a low/mid gain tone out of both amp and pedal to get a tone that had alot of body and not too much gain. For that I used the tweed mode, 10 watt, variac. Settings on the BB: Gain a little less than noon, Treble 12:30, Bass 1:00, and Volume at about 10:00. It seems to keep a tube tone authenticiy while bringing an electrified edge to it. Good luck and enjoy!
