@silverhead Reading this:
He is offering a script that takes a recorded microphone sample of your guitar, along with a recorded sample of your piezo pickup, and creates an IR of the difference. This IR can be placed in your Helix, which would offer the same function as the ToneDexter or Aura, which are $399 and $379 pieces of hardware. You can get this functionality for free with this software and script!
What I am also reading is jonfields45 is offering to do this for you for free, but you still need to send him a microphone recorded sample of your guitar, along with the same sample recorded from the under saddle piezo pickup, again in your guitar. He would then send you the IR to load into your Helix to use with your guitar live.
This isn't an IR to make an electric sound like an acoustic or for cabs with amps.
