The only all-tube amp in the world, produced for Doyle Dykes, with two independent channels, one designed for acoustic guitar and the other designed for electric guitar. Plays solid and ready to go. The tubes are great, and I had a custom cutoff switch installed for the tweeter (really useful if you're mostly using this as an electric amp) in the back. This is a well-made, very expensive amp, and it acts like it. My only reason for selling it is that I’m getting older and it’s a little too heavy for me these days. This amp deserves a good home with someone who appreciates its unique value. $900
