At the heart of the all-tube Peavey ValveKing 100 Head is a patent-pending, Class A/B Texture control that allows variable selection and combination of Class A and Class AB power structures. This gives you the ability to coax a wide range of tones out of the ValveKing 100 Head. It features 12AX7 preamp and 6L6GC power amp tubes; 2 footswitchable channels with independent 3-band EQ and volume; footswitchable boost on the lead channel; global resonance, presence, and reverb controls; a buffered effects loop; and dual speaker jacks in parallel.
