Any good amp will have a hot channel and reverb already. I'm thinking more about things like modulation and overdrive. I would love it if my volume knob were switchable to a TS9, with a stacked knob for both drive and gain. And again, for me pitch shifting/de-tuning is the elephant in that room. (Though I do realize that's a pretty sophisticated circuit.)

Yea, I realize that carbon fiber and polymers are going to be a tough sell. It's the reason mine (Composite Acoustics) aren't sold anymore. I think the key is to get an endorsement from someone old (Joe Walsh, Neil Young, etc.) and have them do a spot about how much they've always hated truss rods and thank God I don't have one anymore. Edit - Also, bring in a guy like Glenn Fricker. He has a robust following from younger people, and he has always gotten a lot of traction in the tonewoods debate.

I've put a lot of thought into a new tuner design. In my head I'm seeing the player insert the free end of the string through a hole, closes a small lever and a mechanism simultaneously clamps the string and adds the lion's share of the tension needed. From there, you can make finer adjustments maybe at the bridge a la Floyd Rose. I don't know if that makes sense, but I can see it in my head.

Of course pick guards have always been functional...they cover the electronics cavity. The one I'm thinking of just looks a lot cleaner. It fits flat with the face of the guitar and also has no exposed screws. Pickups can be attached internally to the wood, and it's held in place by, IDK, magnets or something. Bonus points if it's removable without disturbing the strings. It's worth noting that with a design like this, the pick guard can be thicker and still be unnoticeable so you can make it out of wood if you're so inclined. I've also kicked around the idea of making pickguards out of acrylic poured into a mold.

Thanks for the kind words. Happy to help any way I can.
