I bought two of these to use with my Stickbass, but never play that anymore so I'll let one go. Very nice units with flexible tonal and effectal options. Very well built units. Nothing light or cheapy plasticky about them.

I'm asking $165 shipped cont. US. Would consider trading for a Tone Hammer and a few bucks. Thanks for looking!
