Heya witeter! I think we may have a mutual friend, t'other guitarist in my band (Tacoma Narrows Bridge Disaster) - I believe he knows one of you Insuna guys anyway! :)
Anyways... I use a Fryette Sig X. Each channel is really nice and offers a wide range of tones. Though the KT88 power section is a little 'American' sounding, if that makes sense. Not really like a Marshall - crank a JCM800 or a DSL, and the extra aggressive mid-range bite you get from the EL34's... just sounds lush. I've played a JSX too, great amps. I'd be keen to try out a Peavey 3210 as well, although I had naively assumed it was just a re-badged JSX, since Satch took his endorsement to other places. Could be wrong on that. Will have to try one out!
