The Butterslax is Bill Kelliher's signature head, built with Dave Friedman for the Mastodon guitarist's mix of metal, rock, prog, thrash, punk and psychedelia. It is a hand-wired, 100-watt, three-channel amp running four EL-34s and four 12AX7s, and Friedman is plain about who it is for: this is a gain amp, and players after a clean platform should look elsewhere in the line.
Channel one covers light overdrive up to hard rock. Channel two, by Friedman's account, starts where most metal amps leave off, and channel three goes further again. Each channel has its own Gain and Master, channel one has its own Bass, Middle and Treble, and channels two and three share an EQ. Global Presence and Thump controls shape the top and bottom, and Friedman describes the result as very tight with a deep low end, detailed mids and clear highs. A line out with level control, the ultra-transparent series loop and a 4, 8 and 16 ohm selector cover the back panel, and a two-button footswitch with LEDs comes in the box.
The BE-100 Deluxe is the closest neighbour: also 100 watts on four EL-34s with three channels, but with a Plexi channel and a wider set of voicing switches. The Butterslax trades that range for three stages of gain and a simpler panel. It comes in black Tolex with checkered grille cloth over a Baltic Birch cabinet.
