designed with your advice. The FatRock is based on

consumersʼ requests for a warmer version of our

popular TightRock™ distortion pedal. It ranges from

moderate to high gain distortion with built-in noise gate,

gain boost and PlexEQ switches and it has SideTrak, a

second effects loop that works when the pedal is OFF.

Keep those ideas coming!

Cool Ideas:

• True Bypass switching–buffered when pedal is ON

• Tight Attack control lets YOU dial in the chunk

• Gain, Volume, & Tone with Gain and PlexEQ switches

• Noise gate threshold automatically tracks gain control

• Pre/Post selectable Effects Loop-tracks Bypass Switch

• SideTrak™ Loop comes on when pedal is OFF

• Battery On/Off switch with red ʻDonʼt Forgetʼ indicator

• LED lit knobs when using a DC adapter

good tone comes from tweaking ...
