Letting go of my excellent condition Suhr PT100. Includes the footswitch, slip cover and original box. $2,250 shipped in the continental USA, or $2,000 local in the Vancouver, WA/Portland, OR area.
It's whatever John's circuit is, but it's buffered and completely transparent. You can have 20' of cable going to and from your pedalboard, and switch the loop in and out with no change. It's hands down the best loop I've ever heard.
