LICENSE & USAGE

No direct support is offered for these projects beyond the provided documentation.

 It’s assumed 

that you have at least some experience building pedals before starting one of these. Replacements and 
refunds cannot be offered unless it can be shown that the circuit or documentation are in error. 

All of these circuits have been tested in good faith in their base configurations.

 However, not all the 

modifications or variations have necessarily been tested. These are offered only as suggestions based 
on the experience and opinions of others.

Runoffgroove circuit licensing

Runoffgroove circuits have special licensing that is different from standard Aion FX projects.

 These 

projects are for personal use only and may not be used for commercial endeavors 

without approval 

from Runoffgroove. Here are the terms of use from their site:

runoffgroove.com projects are provided free-of-charge to builders for personal, non-commercial use. We do offer 
licensing for builders who wish to sell pedals based on, in whole or in part, our projects. As part of the licensing 
agreement, the builder must clearly state that the circuit was developed by runoffgroove.com, both in promotional 
literature and on the circuit board. If you see a pedal for sale that seems to be based on a runoffgroove.com project 
and does not credit us, the builder may not be officially licensed by us and therefore, not compensating us as the 
developer. Please contact us with the information and we will investigate the situation. Thank you.
