Rebote Delay 2.5
Rev.3.May.31.2006

This is an attempt to improve on the Tonepad Rebote2 Delay by providing better filtering. Shortest
delay time is 10mS. Maximum delay time is 580mS, repeatsbecome a little dirty with longest delay
times, they are clean on shorter delay times. Off board components except for the potentiometers are
not shown on the layout. Trademarks are property of theirowners. Visit tonepad.com for more!
