I returned another big name looper and got the EHX 22500 instead because most other loopers do not allow asynchronous looping. I love how the EHX 22500’s “freeform” looping allows one to loop channel A continuously while bringing in loop B whenever they want. (Loop B doesn’t have to come in right at the beginning of loop A, and it doesn’t need to be the same length as loop A either). This is great for bringing in a loop for a chorus during a live performance.

However, I do have two suggestions that I think would greatly enhance the value of the EHX 22500.

1. The “double-tap” method of cancelling a loop makes it next to impossible to cancel a loop while performing a song. Thus, the EHX 22500 offers a rare freedom (asynchronous looping), yet the musician has great difficulty actually taking advantage of this freedom because it is so difficult to cancel a loop while singing and playing guitar.

2. The “one-shot” feature could virtually solve the problem I describe above if the one-shot loop could just contain more than a single recording. If the one-shot channel could allow the artist to record several overdubs, but then just play the loop once when it is triggered, then the artist wouldn’t have to worry about double-tapping in order to cancel the loop: it would just cancel itself after playing once (until triggered again).

I would so greatly appreciate a firmware update that provided a “single-tap” option for cancelling loops: even if it was just for loop B (which would likely be the loop that one would use for an intermittent chorus loop).

A POSSIBLE SOLUTION: TAKE ADVANTAGE OF THE OPTIONAL FOOT SWITCH!

I think the optional foot switch might provide a simple way of achieving this objective, as well as solving another problem that so many users complain about with the 22500: namely, the inability to erase loops on the fly.

Perhaps a firmware update could expand the functionality of the foot switch, allowing the user to depress both pedal buttons simultaneously in order to toggle through two or three foot switch modes: Mode A: Foot switch toggles through memory bank locations. Mode B: Foot switch serves as an instant cancel button for loop A and loop B. Mode C: Foot switch allows the user to erase either or both loops in the current memory bank location.

I would think that such an update would make the EHX 22500 the clear choice for any musician who wishes to loop while performing live.
