What??!!?? Another brown Princeton? Yep, this one's got an Altec speaker. The guitar is a 60's Gibson 330, P-90's swapped out long ago for 60's humbuckers. Replaced the gone-concave ABR-1 bridge, now it plays like a dream! (And before you ask, no, neither the guitar or the amp is for sale!) Got an amp, keyboard, guitar or bass that's not behaving? Come on down!

A real piece of North Bay history here. This silverface Fender Deluxe Reverb was modified by Randall Smith back in the pre-Boogie days. From all appearances, Randall was the last tech to open this thing up, so it was deferred maintenance time. New tubes, new filter capacitors and various other bits and bobs and it's ready for another 50 years.

One for the rockers: 2014 Marshall DSL100H with new output tubes, a couple of very minor nicks in the Tolex and a bit of discoloration on the faceplate, but functionally perfect. Test your neighbors' patience this holiday season! $500

As we all know, George didn't need no wah-wah, but maybe you do. Here's a couple of nice ones! An original purple Budda BudWah, missing its logo plate but otherwise in good shape. Next up a Crybaby GCB95 with the Joe Gagan deluxe mod kit installed, giving you the option to tune the wah to your heart's content. $150 for each.
