I just purchased a sceptre head at a pawn shop. I am running it with a 4-12 Laney cabinet loaded with H-H speakers and it kicks. I am looking for info on the sceptre head, like output? It has reverb, tremelo, contour, volume, treble, bass, mid boost switch. I found a jack on the back panel near one of the output tubes. Any idea
what this is for? preamp out maybe? Are all sceptres 100 watts? It certianly is loud and clean. I use a strat and RP-12 and it is great for loud gigs.
