The StompLab IIG from Vox is a modeling effects processor designed for electric guitar. Featuring 120 presets (100 stock, 20 user-assignable) and an on-board expression pedal, this unit emulates amps, cabinets, EQs, modulations, delays, and reverbs. The presets are categorized by genre into ten separate banks, with each bank containing ten different combinations of amps, pedals, and various effects. You can program the user presets with the edit button, which converts the category, gain, and value knobs into controllable commands over all of the pedal's built-in parameters—parameters which can you can save and recall whenever you need them.
On the stage, you can twist the StompLab's knobs for gain and effect manipulation, while the on-board expression pedal provides real-time foot-control over assignable parameters. The unit can be routed to an amplifier or directly into a mixer or PA (in mono or stereo); the choice is yours. As an additional feature, this pedal offers a tuner with a six-octave range and an adjustable point of reference: You can assign that all-important "A" to any frequency between 438 and 445 Hz, so if you need to tune to European orchestras for some reason, such a feat wouldn't be a problem.
