COOL GEAR ALERT: EHX Tortion

The EHX Tortion uses JFET overdrive for tube-like response and tone, has a Boost switch with independent Volume and Gain for two-channel flexibility, and features a four-way Pre-Gain selector plus Treble, Middle and Bass for complete sound control. It also has a balanced XLR output with cabinet emulation if you wish to use it as a preamp.  More info here.
