For your own presets, I think the donation route is the way to go.
On the other hand, you might consider charging for consulting. In a consulting role, you work with the client until the client achieves their goal. There is more iteration and the goal is for the client to be happy. You are helping them tweak it to their taste.
I'm thinking about how much time it would take to tweak that patch per person and how it can be worth doing it. And what are the guarantees if the patch isn't 100% there but needs some adjustment here and there etc? Many questions unanswered.. but sure.. if someone would pay... even $5 for that service and it takes an hour to load up that sound and reamp it through the Axe-Fx and create that patch I don't see that as something very effective. $5 minus tax is like $3 in reality. And what about if the patch uses commercial IRs? There are no rights to resell digital products.
I just wanna have your opinion whether or not you like to pay me for a patch which you think it's worth of paying !, and also the time I spent for that !.
i think the patch sounds great but thru the past couple yrs there have been some dynamite uploads along w/ the dross that would make it impractical to pay for just one good patch. besides it was pointed out depending on the gear used, a patch may need much tweaking anyway. keep up the good work- very impressive! :mrgreen
