The Peavey ValveKing 100 head features a patent-pending, variable Class A-A/B control called Texture, 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 the ValveKing 100. The amp's preamp and power sections use 12AX7 and 6L6GC tubes, respectively.
Additional standard features on the Peavey ValveKing 100 head 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. The ValveKing 100 head also features global resonance, presence and reverb controls, a buffered effects loop and dual speaker jacks in parallel (head and 212 only).
