the best solution for the extra 1 hp space that odd-count modules cause is to use at least one of those spaces to put in a Konstant Labs PWRchekr

Interesting! I didn't realize there were 1 HP modules that weren't just blank. This indeed seems useful. My case does not have any such indicators.

i went with erica dual fx. for the most part im happy

Oh, I missed this option. The FX aren't quite the same but it looks almost like two Pico DSPs in one module. I wish with the bigger form factor there were more CV inputs for control of both FX parameters at once, but it still looks like a reasonable option. And it seems you can switch between controlling the different parameters (or wet/dry) with the CV input, unlike the Pico which only let's you control parameter 1. So the added flexibility is a good step up from the Pico.

Responding to myself from earlier in the thread:

I found one retailer in England selling [an FX Aid XL] but it looks like they won't ship to me in the US. Sigh...

It turns out they had an issue with their checkout system, and they do ship worldwide. We got it straightened out and I managed to buy their very last FX Aid XL! I had spent a long time looking and I think I may have been very lucky and got the last one in the world (at least a brand new module from an official retailer). Crazy. Now I'm just hoping it arrives in perfect working order next week 🤞 but I think I found a great replacement for my ALM MFX.

BTW I had emailed Happy Nerding and Igor responded. It sounds like he's hoping they can make a new batch outside the Ukraine in 1-2 months. I hope he can get back on his feet!
