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.

Projects may be used for commercial endeavors in any quantity

 unless specifically noted. No 

attribution is necessary, though a link back is always greatly appreciated. The only usage restrictions 
are that 

(1) you cannot resell the PCB as part of a kit without prior arrangement

, and 

(2) you cannot 

“goop” the circuit, scratch off the screenprint, or otherwise obfuscate the circuit to disguise its source

(In other words: you don’t have to go out of your way to advertise the fact that you use these PCBs, but 
please don’t go out of your way to hide it. The guitar effects industry needs more transparency, not less!)
