Are there any? Wizard is awful. Logical sound did basically on my warranty repair and then charges me $100 to replace a freaking jack on my head that I could do in 10 mins. Oh yeah the problem is still there. Needs the mosfets biased, then the lady is explaining to me what it would do if that was the problem as its doing that. Then goes on to tell me that the mosfets are fine. I also brought my cab and bass and she tried to blame it on my new mesa 212. Saying that some models are better then others! Yeah guess the svt 3 pro is horrible even though it's the number one selling amp of the series. Needless to say I need a amp repair place that will actually fix the problem and not try to screw me. Really frustrating because Im tired of throwing away my time and money just to get screwed and still have messed up amps. Now Im probably going to have to sell my Made in America Svt 3 pro just because no one around here actually cares enough to fix a simple problem.
