Engl Alpha-Drive EP03

With the ALPHA-DRIVE pedal you get pure analog, medium gain, vintage overdrive sound just like a cranked up tube amp at high volumes. It is designed for classic and blues rock but you can use it as a simple drive booster, too.

Controls:

VOLUME – Controls the output Volume. Left is less, right is more.
LO FREQ – Controls the amount of bass frequencies. Left is – 7.5 dB, right is + 7.5 dB
Hi FREQ – Controls the amount of treble frequencies. Left is – 7.5 dB, right is + 7.5 dB
TRUE BYPASS – This Footswitch turns the pedal effect on and off. When the effect is off, the signal is routed directly form the input to the output jack (True Bypass).
