Etiquette question, for want of a better term...
I quite often find rigs on rig exchange that need a fair bit of tweaking to sound right, at least to my ears and with my guitars. So I'll adjust them, add stomps if they don't have them, generally tidy up. I'd like to share the results but I'm not sure what the best way to do this is without upsetting whoever put the rig I used as a base up in the first place.
I guess there are two questions - what's the license for rigs uploaded to rig exchange, and what's the *polite* way to do this that won't upset people?
