Peavey Valve King amps feature a patent-pending, variable Class A/B control called Texture, the first and only amp control to allow sweepable selection between Class A and Class B power structures, as well as any combination of the two. With this exclusive feature, guitarists can coax virtually any tone from this tweaked-out amplifier. The amp's preamp and power sections are powered by 6L6GC and 12AX7 tubes, respectively, and drive specially voiced 12 inch Valve King loudspeakers. Additional standard features include two footswitchable channels with independent, three-band EQ and volume, plus a footswitchable gain/volume boost on the lead channel to provide extra volume for solos. Valve King amps also feature global resonance, presence and reverb controls, and a buffered effects loop.
