This Effects Pedals 3 way toggle switch allows you to choose from a hi boost, low boost and off boost. Additional shaping is achieved using the gain and tone controls. You can use the Lo and off boost positions to get a great rhythm tone. In this position play with the tone and gain knobs to recreate tones from your favorite bands or uniquely create your own sound. Then switch it into Hi-Boost for a face melting solo.
