I know there are some out there but I don't know any off hand. Little help?
http://www.thdelectronics.com/product_page_main.htmlI'm unfamiliar with these amps. Are they decent? Good tone? High gain? Low gain? Cleans?
What do these cost?
Yep. I have an Invader MkII which also has it. Don't believe he makes them anymore though as they were not economically viable to produce - need to find them used.
