Tube-Tone Amplifiers

 This is essentially the AB763 circuit used in the Fender Twin-Reverb blackface models from '63-'67 with some additions that don't affect the original tone of the amp, such as 4 individual bias control adjustments for each power tube, added half-power switch, and impedance selector.  The one pictured here was a special order with bluesbreaker grill cloth, black leather style covering, Marshall multi-tap output transformer, and an added MID/FAT boost footswitch, along with a mix of the Weber Silver Bell and the Weber Ferromax 12F150A 12" speakers.  Normally comes with Weber California Ceramic 12" speakers.  Email, or call for pricing and options.
