The Pigtronix Attack Sustain is a better unit.

Tape Reverse effect – Expression pedal

I bought a Memory man with Hazarai last year and an AttackDecay pedal a while later.
A realistic Tape Reverse effect still seems quite elusive to emulate. Not quite satisfied yet.
The greatest problem creating a realistic Tpe Reverse effect seem to be:
1 – Playing a solo it consists of longer and shorter notes. Thus geting the Swell and Decay function correctly.
2 – With many pedals out there you cannot decouple the reverse function from the delay function (MemorymanHazarai, Line6 Pod, Danelectro BackTalk etc.)

The Memory Man has a nice cutoff at the end of the tone, just like the real thing when the pedal control knobs are at their most extreme position. But the downaide of this pedal is that even at its most extreme setting the signal cannot be totally dislocated from the delay function i.e repeats. Another downside is that it takes a while for the signal to get started in this setting after picking the note.

Now the Attack Decay pedal does not suffer from these repeats since it is not coupled to a(digital/anaologue)delay.
But a real Tape reverse guitar swells slowly and then is suddenly cut off at its apex.
With the Attack Decay the signal fades away slowly at the end. This can be altered of course with the Decay-knob but then you get these staccato like repeats. Now it sounds more like the Japanese Banjo from the EHX instruction video(when trying to shorten the cutoff by turning back the decay knob counter-clockwise) which is not at all what you’re looking for when trying to do a Tape Reverse effect. Consequently you have to turn down the Attack-knob now too but that doen’t do the trick.

Furtermore: When playing a solo it consists of longer and shorter notes. This is a problem for the Attack- and Decay-knob on the AttackDecay pedal.
Try playing the “Castles made of Sand”-solo correctly with this pedal. You’ll have a hard time.

The manual states that an EHX Expression foot Pedal can be hooked up to the Attack Decay an give you direct control over each control-knob on the Attack Decay.

My question now is:
1- does anyone have some experience with an Expression pedal on the AttackDecay (decay/attack-knob),
2- and more specific in creating a more realistic cutoff at the end of the guitar note like on the Memory Man Tape Reverse effect.
3- Or could this cutoff (like the MemoryManHazarai)be achieved by other technical means?
