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.
