I pushed the gain control and ahead of me distortion screamed through the air...

The Hayes Effects Boost! is a positional boost pedal with a built-in loop. Stack your gain pedals between the loop in and out and, with the tap of a switch, choose whether you boost before or after your loop.

The Boost

The MOSFET boost circuit is based on the ZVEX Super Hard On, an ultra-transparent boost that goes from clean to crunch in just a crackle. An LED indicates whether the boost is engaged.

The Switch & The Loop

The flipper switch enables you to choose where the boost is positioned, before or after any pedals you place in the loop. The position of the boost is indicated by a pair of LEDs.

Place a drive pedal into the loop and use the flipper switch to boost the volume, or boost into the drive pedal and drive it harder.
