Who's a good boy? This amp and our special guest model! This Fender Musicmaster Bass chassis came here in a box, partially disassembled. We put it back together with new filter capacitors and a few minor mods to make it a great sounding guitar amp. The owner did the cabinet and the spiffy new grille cloth. It'll make you sit up and take notice!
The Tale Of Two Princetons
Up first, this beautiful brown Princeton we rebuilt for Star Guitars in Santa Rosa. Ever-tasteful Connor Gill displays its tonal majesty. Next, Connor again, this time playing through a 1971 Princeton that we modified for more clean headroom while completely rebuilding it. This amp could be yours. Also, an Explorer with a Bigsby! Seriously, how cool is that?
Here's the vintage Silvertone, bridge reattached, stripped tuner screw holes filled and redrilled, controls cleaned, dead tone control toggle switch replaced, Connor Gill playing it through the Fender Musicmaster Bass amp that we modified to be a sweet little guitar amp. Got an amp or guitar that needs some love? Turning most repairs around overnight or within a day or two right now--come on down!
