Up for sale, a 1966 Supro Vibra-Verb model 6498 VR 2x12 vintage tube amp in excellent condition and in perfect working order. The top of the line Supro combo in this era, the Vibra-Verb 6498 VR has "genuine vibrato," as its faceplate text purports, along with built-in Reverb. Produced by Valco in Chicago, USA, this Supro has a very original and fully serviced circuit.
Powered by a pair of matched vintage 6L6GC power tubes, the Vibra-Verb delivers a sparkling clean tone that cascades into saturated, harmonic-rich overdrive at higher volumes. Supro's '60s circuits have an extremely musical, dynamic sound, and this Vibra-Verb is no exception, with a two channel design that offers dedicated Volume and Tone controls for each channel (the Vibrato and Reverb effects are dedicated to Channel 2). The vibrato has a thick, watery warble, and the Reverb has a trashy, splashy quality indicative of the small Gibbs tanks used in these circuits.
The circuit has tag board construction and original CTS pots with a virtually untouched preamp. The transformers were manufactured by Triwec, and the original output transformer and choke are intact with 1966 date codes. The power transformer is a vintage replacement. The tube set includes properly matched vintage 6L6s (different brands), with a JAN 5U4 rectifier and modern valves in the preamp. Both Jensen C12PS speakers sound great with clean black frames and gold foil labels on the ceramic magnets. Date codes on the edges of the frames are from the 8th week of '66. A modern three-prong power cable has been installed.
Cosmetically, this amp is quite well-kept, with a chrome-plated chassis that shows some patina through the plating, retaining virtually all of the black silkscreened text and all of the original knobs. The textured bluish gray covering on the cabinet shows very little wear save for some minor scuffs and a few small mounting holes on the underside from a previously removed set of casters. The original silver sparkle grillcloth is also intact, and the large chrome-plated handle tops things off.
