Up for sale or trade is a USA made Svt 4 Pro. Formerly owned by TB’s own Warpeg. The amp is in great shape. Between me and the former owner it has remained in a shock mount case. I’ve used the amp on a recording and a few gigs and as much as I LOVE the tone of the amp, the weight of the amp plus shock mount case is getting a little too tiring to carry around to gigs. This amp is a BEAST! I played this with a few different active and passive basses and I was never able to push it too far. Included with the amp I will throw in a speak-on cable used to run the amp in the mono-bridged mode. It has three Sovtek's "higher end" voltage matched/burned-in 12AX7-A's. These tubes really make the amp sing. Alone the tubes are around $25 each. They have about 30 hours on them and were never driven like they should have been. I think I may have pushed them once during recording just to get to the “sweet spot”. I will put this up against any MIV ampeg or even other USA ampegs and say it sounds better then any other 4 pro I've heard.
