The Pinnacle is actually two overdrive circuits in one pedal, and when both are on at the same time (depending on the pedal's settings) an aggressive distortion screams at you. Or keep it on overdrive at your rhythm volume, and use the other as a lead boost. Want crunch? Turn up the tone knob.
This pedal has a total of 6 knobs -- a volume, tone, and gain for each overdrive circuit. It is completely true bypass, of course, and includes a 9v "boss style" power jack, but no battery jack as it draws a ton of current in order to clip (distort) the signal just right without being fuzzy according to the maker.
A switchable bass boost option is available as well.
