Hey!
Before sending it off to a modder, you might want to confirm whether you want the dry signal permanently disabled when the pedal is active, or switchable. That’ll affect how invasive the mod needs to be.
If you’re not DIY-inclined, I’d reach out to smaller boutique modders rather than the big brands — they’re usually more open to custom work. A local amp/pedal tech could also handle it if you provide a clear description of what you want.
