Atlanta, GA (April 17, 2015) -- Due to customer requests, the Spectraverb 22 and Spectraverb 40 amps are now available in head, 2X10 and 2X12 combo versions. Like the 1X12 combos previously introduced, the newest Spectraverb amps offer surprising clarity and headroom while delivering a smooth, touch sensitive response and complex warm harmonics. The new head cabinets are designed in the proper dimensions to accommodate our spring reverb system without the introduction of noise that is often found in shorter cabinets.   

The Spectraverb series amps are available as heads, 1X12, 2X12 and 2X10 combos and feature locally-built heavy-duty solid pine or domestic birch plywood cabinets and are hand-wired on heavy-duty turret boards in the USA. Spectraverb amps are upgraded versions of the famous AB763 vintage “Blackface” models
