I do want something I can just buy and use out of the box. The hothouse seems to come close, but it'll add up to $180 once you include assembly and the daisy seed.
Hopefully if the concept catches on more there will be more options for hackable pedals on the market.
The polyend pedal being discussed is $299, plus whatever tokens you end up using. So $180 is a steal relative to that.
Also, those were just the three first ones from memory + a quick google, there are probably other options - but i doubt you’ll find anything under $150. Pedals are not cheap, except when mass produced - and a programmable dsp pedal is by definition niche.
Another option, for people willing to hack a bit, is that the FV1 dsp chip is used in a ton of pedals, and is pretty hackable if you wanted to load your own code: you could find a cheap pedal that uses that chip and hack it.
