You can use the Vise Grip for everything from a simple dynamics adjustment - like a subtle or extreme increase in sustain, or a little extra clarity, body and volume for a clean solo - to more intense effects like a classic ‘squished funk’ rhythm scratch or a lo-fi, treble-heavy edge which is perfect for garage-band vibe. Then you can blend in just the right amount of the uncompressed signal and let the Mid/Full/High switch restore sparkle to the high end, fatten up the uncompressed signal for increased harmonic overtones, or simply make sure your effected sound remains consistent with your bypassed guitar tone.
