This is a 100% handmade overdrive pedal. It's based on R.G. Keen's Son of Screamer which is a bufferless TubeScreamer. I've made few changes from the original design. I built the board and hand painted then etched the enclosure. If you haven't noticed, I have a sense of humor about TubeScreamer clones. This one is a medium gain overdrive. More clarity than the original. Looking to get $85.00 shipped in the U.S. Shipping outside of the U.S. is an extra $10.00 U.S.
