...........had a feeling that tech 21 wasnt tube.........
there is only one more amp i would suggest - i own one , its cheap not complicated, tons of different tones and its a Vox
Valvetronix Ad15vt - 15watt tube in the preamp, sounds great
or the Vox vr15 - another 15 watter
i got the ad15vt for 420 (Aus dollers) and over here they rip people off
just throwing in a couple of suggestions
