1. VOL Knob – Sets the master output level of the Attack Decay.

2. BLEND Knob – Normally BLEND is a master wet/dry mix between the

dry signal present at the INPUT jack and all of the effects produced by the

Attack Decay. The output of BLEND is sent directly to the VOL knob. As

BLEND is turned clockwise, the effect volume increases while the dry

volume decreases.

 Optionally, BLEND can adjust the mix between dry and Harmonix

signals before they enter the volume envelopes, replicating the

Harmonics knob from the vintage Attack Decay. This allows for a mix

of the clean and fuzz instrument tones to be manipulated by the volume

envelopes. As BLEND is turned clockwise the fuzz volume increases

while the clean volume decreases. See page 15 for details on adjusting

Harmonix Blend.

 The BLEND knob has a third option that mixes the signal at the RETURN

jack with the output of the volume envelopes. To do this, Return Blend

mode must be activated and a plug must be inserted into the RETURN

jack. See page 16 for details on adjusting Return Blend.

3. ATTACK Knob – Sets the swell or fade-in speed of the volume

envelopes. As you turn the knob clockwise, attack time increases. Turn
