McCaffrey Audio Green Vodka Muff Fuzz Pedal Increases/decreases the amount of fuzz/drive/gain. This isn&rsquo;t your ordinary muff clone. Try it in different positions to get everything from classic green muff sounds to modern chunk! Tone:&nbsp;Controls the highs and lows of the pedal. Has a very wide sweep and works in conjunction with the Volume control. Beef Switch:&nbsp;Two-way switch on the top left of the pedal. Right is the &ldquo;stock&rdquo; mode and left will allow you to cut through the mids even more. Pass Switch:&nbsp;This is a three-way toggle switch that was conceived with the many mods that I used to do on Big Muffs that folks sent in looking for a high/low pass filter mod. Made in the U.S.A.
