Please clarify: in loop mode, feedback works as it should to control attenuation, but when looping in delay modes, you can’t control attenuation, and the loops are fading after 5 passes. Correct? Is this different than your experience in the last year? I ask because this is how I’ve always known the SMMH to work.

When layering over a loop in loop mode, feeback controls attenuation, but in delay mode, your feedback control is for the delay that you’re currently on, not for loop attenuation. By 6 passes or thereabout, in a delay mode, I find that there is a natural reduction of earlier loops as you’re describing. Let me know if that info helps or if I’m missing something.

Ok, I did what I said I would do (A first!) and here’s what I came up with.

I started in loop mode with repeats set at noon, and switched to 1 sec echo. I did simple 8 bar riffs and kept layering in around the same sonic space (all on the d and g strings, around the 10th-12th fret). By the time I got to 6 layers, I could no longer distinguish between what I played first and what I played sixth.

I switched back to loop mode and maxed out the repeats, then switched back to 1 sec echo. I played a bass line on my low strings in order to make something stand out and rest in a different sonic space, then kept layering in the higher range as described before. I could still hear the bass line by the time I got up to 6 layers, but it definitely had faded somewhat.

Here’s my perspective: Turning the repeats knob to maximum in loop mode does not carry over when I switch to 1 second echo. If I was in loop mode, I definitely could have put a bass line, tap out a drum beat, put in a guitar line or two and would have heard each instrument. In echo mode, with effect minimized, I got similar results. But in both cases, it had to do with where the sounds were residing in the spectrum. If I had 1 sec echo on and looped a heavily delayed riff and then added more layers in other modes, like 3 sec+mod for example, all in a typical range for guitar, all the sound just mushed together.

So my view on this is that your pedal is working now as it should be. I think your early impression that it does not attenuate in delay modes came from whatever you were playing at the time not really pushing the limits of what you are trying to accomplish recently. Also, I think there is a limit on the memory, so your early impression may have been a 10 second loop and your recent experience might have been 30 seconds, so layering ability would run out sooner.

Hope that helps.

Happy to help. Rock on! :thumb:
