This 80s vox combo is very much in the marshall 18 watt camp rather than the ac15 camp. She features a JCM800ish preamp stapled to a dual el84 power section that incorporates negative feedback.... stock it sounds okay, not terribly voxy and a little stiff. If you adjust some component values you can get it to sound a bit like a Marshall 18 or 20 watter or if you lift the negative feedback loop completely it will get more ac15 character, though due to its marshally preamp topology it will still do its own thing. I really want to pick one of these up and perform some surgery. They are very affordable vox combos that fly way udner the radar.
