What can I say about this preamp that hasn't been said? Probably nothing. Damn fine preamp. Awesome tube emulation and great grind!! An industry standard for a reason. Only selling cause Daddy needs a new cab! Excellent condition, no quirks, bugs are anything unusual (with the exception of the previous owner writing "AI above and at the footswitch jack for easy recognition, never bothered me, so I left it). $225 shipped. Ho, ho, ho!
