I currently own and run out of a 72 Sunn 190B tube amp. I have 2 1X15" Lopo Line cabinets loaded with Eminence Deltas. I am happy. As some of you know, I use effects (POG and Hot Tubes +Chorus mainly), but also like to shut all of them off and hear the amp tone. My amp is very loud but controlled for sure. My Girlfriend uses a VERY dominating Sunn Beta Lead SS amp plus lots of EHX goodies and she says I don't have enough LOW END...she and I get into lots of arguments when I start cutting lows and boosting mids just to be heard and balance with the drummer. Well that aside, I just got an Acoustic Control 220 amp. I was thinking that I wanted to use the Sunn for Tube sounds and the Over Drive (valve) effects and somehow get another 2 1X15 cabinets w/8ohm impedance and use the 220 for the chorus, POG and delay etc. This way I can maintain the growl from the Hot Tubes along withe the nice Tube Warmth of the Sunn, and still get the delay, chorus and expressive middy stuff from the other, SS amp. If this is impossible or too far fetched an idea, please stop me before I accidentally electrocute myself I am using a Fender Jazz 24 currently, and I am in the process of getting a Gibson USA Thunderbird bass to use on songs that need even more boom.
