Here's what I propose;
An app that would allow us to "design" our own tube amps that we can upload onto the Helix and share with other Helix users.
The amp would allow us to mix and match all components of an amp and its design paradigms (Fender, Marshall, Boogie, etc.) and swap out tubes, caps, resistors, pot values, negative feedback amount and "power supply" robustness (sag/tightness). Mix and match manufacturer designs between preamp and power amp. All without the danger of electrocution and being able to ignore most the laws of physics and electricity. I'm thinking of this as something along the lines of the Variax Workbench. You don't have to understand electronics and tube design, just be willing to experiment.
I'd be willing to buy this app. It doesn't need to be free.
Please upvote it.
