I had the original SansAmp at one time, It was a killer little unit, also had a mesa 50 calibar at the same time and some nights the SansAmp would just kick it's little ass! Hot-rodded Marshall tones?(oh yea) but if you do a little searching in the mp3 forum you'll more than likley hear "THE POD"!! and it sound's damm awesome!...I'll shut up now.
