GREENHOUSE IS STILL IN DEVELOPMENT STAGES AND IS NOT READY FOR RELEASE
The idea of Greenhouse is simple: you have a pedal that doesn’t have tubes, and you want it to sound like tubes. You can’t stick tubes inside the pedal (usually), so the best way to do it is to wrap the pedal in a tube sandwich. Greenhouse features a tube input stage, a send to your pedals output, return from your pedal’s output, optional blend with your original clean signal, and a tube output stage.
Update June 2022 – I have a working prototype for Greenhouse that I will get boxed up for thorough testing. I hope to have it ready for release by August 2022. Estimated price is $250.
