All user reviews for the Laney TT20

Full-Amp 2xEL84 valves, 2xECC83 and 1x12AT7-C. If you have the means, replace the EL84 with 6L6. (Note: This is not possible without substantial mechanical and electrical alteration. 6L6s use IO valve bases, EL84s use B9G. They are not interchangeable)
-20W
-2 Jack inputs. One High gain and low gain, the two rear speakers connections (on head, combo has one external speaker connection), footswitch socket, send and return fx, Fx serial parallel selector 
Cabinet-Celestion 12 'Seventy 80
-Single Channel
