Peavey ValveKing(R) amps feature a patented, variable Class A-A/B control called Texture(TM), which allows sweepable selection between Class A and Class A/B power structures, as well as any combination of the two. With this feature, guitarists can coax virtually any tone from this tweaked-out amplifier. The amp's preamp and power sections use 12AX7 and 6L6GC tubes, respectively, and drive specially voiced 12" ValveKing(R) loudspeakers (112 and 212 versions only). 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. ValveKing(R) amps also feature global resonance, presence and reverb controls, a buffered effects loop and dual speaker jacks in parallel (head and 212 only).
