T-REX Engineering Spin Doctor 2: (For Sale or Trade). Triode Programmable Pedal and Preamp, very lightly used. Mint condition. It works great as either a multi-channel preamp (Switchable) for digital amps or as a distortion pedal with 4 presets in front of an amp. Does everything from light breakup to heavy crunch, with lots of variation in between. The pedal allows versatility in having 4 overdriven presets available in 1 stomp pedal and being able to EQ each preset. You can get lots of detail and clips on T-Rex's site, here's just a bit from their description: • 4 channels of T-Rex tone. For each channel, you set the gain, tone and output exactly how you want it. Switching between channels and making adjustments on the fly is simple, fast and intuitive. • Tone controls let you tune your tone (bass, mid, treble and presence) for each individual channel. When you switch channels, all your settings change too giving you the perfect depth, sustain and edge no matter how much gain you apply. • Very cool motorized knobs move when you switch channels – like faders on a state-of-the-art studio mixing board. They also provide mission critical visual cues that let you monitor your settings at a glance – and adjust them in no time. • Gain gives you the entire spectrum of analogue gain in a single knob. Turn it down low for a warm clean sound. Turn it up to lay on the gain – and hit the boost button on each 4 channels for lead rifts that cut through the mix.
