OUR PART # SOLO
Pro Co's SOLO features the standard "distortion", "filter", and "volume" knobs of the other distortion pedals in their line, but features two distinct differences.
Asymmetrical Clipping - Three switchable selectable levels allow you to adapt your sound from a low wattage vintage tube amp effect, to a modern high wattage, high gain head unit. These settings are marked as "HOT", "MELT", and "BURN". This is equivalent of having three different distortion pedals in one. These are accessed via the three way switchblade on the top of the unit. ProCo also suggests using the lowest setting to lower the overall volume of the pedal without losing any of the distortion.
Scoop - This allows you to select the amount of mid range frequencies that you would like to remove. Used in concert with the tone control, you have an extremely wide and diverse tonal pallet from which to choose. It is much like having the mid range control of a parametric equalizer at your fingertips.
ProCo has also opted to retain analog circuitry over digital. Analog circuits have long been thought of as having greater warmth and a more lively sound than their digital counterparts. Based on my tests, I think this was a very good decision on their part.
The SOLO runs on a 9 volt battery or with the optional AC power adapter (not included). Like all ProCo effects, the battery compartment is easily accessible via a thumbscrew with no tools required.
