Tip for Marshall AVT amp owners

[nero1985]

i was messing aroun with mine an AVT150 combo, it didnt have as much output as i thought but i did something that gave me a little boost,

#1.- i changed the tube for a GROOVE TUBES 12AX7\

#2.- i put a jumper cable on the FX LOOP (one end on SEND and the other one on RETURN) and now and set the FX LOOP MIX control to 10 and also i left the button on the back for the loop on +4dbV this will give u a slight boost that makes up for the lack of volume and it should work on most AVT amps
