what should i do ....i got a 100 watt tube amp...distortion is good ....but i was thinking of tweaking it a little for more crunch...better tone for leads...i would like to use my overdrive channel on the amp and get a pedal to juice it up a little more what pedal do you guys suggest????....when i use a distortion pedal on clean it seems i am back to solid state ....p.s. does the effects loop opposed to just going straight in make a difference????
