This Gehring Fender Vibroverb Conversion Amp is another brilliant custom combo amp from amp guru and mad scientist Jeff Gehring. What you have is an amp with amazing power, killer tone and a lot of mojo. You've also got two Weber Vintage Series 50-watt speakers - one 10" and one 12" and they make for an outstanding pair. He took the chassis from a 1969 Bandmaster Reverb, took it apart, cleaned it, and rebuilt into an AB763 Vibroverb (with a reproduction faceplate). Of course Gehring sweetened every wire and part along the way. The output transformer was replaced with a beefier Hammond unit, the electrolytic capacitors were all replaced; the filter caps were replaced with Sprague Atoms; and the parts boards were completely removed, depopulated, cleaned, and reloaded with new parts.
He also removed the Silverface-era PVC wiring and rewired this beauty with new vintage-style cloth insulated wire. The coupling caps used are a mix of Mallory 150m type and new, old stock Black Beauties. One-ohm bias current-sensing resistors were added to the power tube cathode connections to make checking the idling current easier to do too.
If you're a vintage tone fan looking for something really reliable that you can gig with for decades to come, this Gehring Fender Vibroverb Conversion Amp is the one for you. Local Lawrence, Kansas pick up only.
While it by no means showcases all this amp can do, here's a quick video snippet of Eric M. playing our latest Pickup Test Drive Guitar through the Vibroverb, surf-style!
