Orange Thunderverb 50 head and PPC OB212 cab, awesome amp and delivers classic British valve amp tones across the board on both channels. It also has an attenuator for when you practice at home. Bit heavy for gigging but I have a strong roady. (My husband)
Laney VC15-110 practice amp although its pretty powerful and linked to a cab its idea for smaller venues.
Laney LA 30C acoustic amp (solid state)
Both the Orange and VC 15 are valve (tube to our American cousins)amps.
Also quite a few amp emulations in Eleven a plug in for Pro Tools.
