This Gehring Sgt. Pinback Amp Head is a chimey, British-flavored 30 watt head, featuring a post-phase inverter master volume - expertly crafted by local amp madman, Jeff Gehring. The 1/2" Birch void-free plywood cabinet is expertly covered in black Taurus Tolex and is accentuated by a red alligator-patterned cowhide leather detail panel. The valence panel is figured Maple, stained black, with brass trim - all together, this is an astounding amp, both visually and sonically. Like the Gehring Darkstar combo, it doesn't use negative feedback on the output stage, so going from a clean tone to some breakup is gradual, allowing for more control from the guitar volume and pick attack, rather than just the amp itself.
A Bright switch, Volume, Treble, Mids, Bass, and Master Volume controls are on the front panel. On its back panel are a Bias selector switch, a 4/8 ohm impedance selector, and a switch to defeat cathode bypass capacitor on the output stage (when cathode bias is selected). Incredibly cool and versatile, the Gehring Sgt. Pinback Amp Head is one of the best looking heads we've had, and sounds even more impressive.
