Only for sale as I can't justify having this and a Thunderfunk TF550B! Spec can be found on the Tecamp website but briefly it is a full tube preamp (x3) with a 1000 watt digital power section. 2x500w @ 4ohm each side or 1x1000w @ 8ohm. A very simple EQ that is really dependent upon the input AND output gain, the more you wind up the gains the more dramatic the affect of the tone controls! At low volumes (in the home) the EQ appears to do very little but as you increase the gain to rehearsal
