The PT100 Signature Edition is Pete Thorn's signature head from Suhr: 100 watts from four EL34s through a custom Plexi-style output transformer, six 12AX7s, three channels, MIDI switching and a 4-button programmable footswitch. It is dressed in black tolex with black knobs and a midnight anodized aluminium faceplate.
Channel 1, the green channel, is an American-voiced clean with a firm low end, plus a Crunch mode for medium-gain overdrive. Channels 2 and 3, blue and red, are the high-gain British side, descended from the Custom Audio Amplifiers high-gain circuit. A high-voltage MOSFET boost can be toggled on any channel, and each channel can be set to come up with the boost on or off.
The solid-state loop runs series or parallel; in parallel, your effects need to run 100% wet. Dual-layer circuit boards pair with hand-wired pots, jacks, switches and power tube sockets, assembled in Lake Elsinore, California, for life on the road. Suhr's published specs for the PF100 Signature Edition Head read the same in power, tubes and panel layout. For 15 watts, there is the PT15 Head. Suhr's PT100 2x12 Deep Cabinet carries Celestion Creambacks, and a PT100 4x12 Cabinet is in the range too.
