Whats inside
Every part of this experience exists because of this masterclass moment.
Nothing here is accidental.
Gristle ST Guitar With Case - Signed
Three Tone Burst
The Greg Koch Signature Gristle ST delivers top-of-the-line performance across every component. Reverend Pin-Lock tuning machines provide rock-solid tuning stability and lightning-fast string changes, while the patent-pending triple-tree string tree secures three strings at once to reduce friction and prevent G-string buzz at the nut.
A Wilkinson VS100N tremolo elevates the classic S-style design with smooth, controlled action and locking steel saddles. At the heart of the guitar are Greg’s signature Fishman Fluence multi-voice pickups, offering exceptional clarity, dynamic response, and tonal flexibility without sacrificing feel or character.
Your Gristle ST will be signed as part of this limited run.

Personalized Playing Video
Greg records a private video playing your exact guitar, including a full rundown of the instrument and personalized with your name.
Greg typically records demos for serial numbers, not individuals, so this kind of personalized video is a rare, event-specific addition to this experience.

One Hour One on One With Greg
Once your Gristle ST ships, you'll sit down with Greg for a full hour, just the two of you, to work on whatever your playing needs most. Bring a tune you're stuck on, a technique you want to nail, or questions about improvisation you've been sitting on for years.
This isn't a script Greg runs through. It's your session, built around you.
You'll walk away with more than the memory. Every lesson is recorded, so you get the full video to revisit anytime, plus a PDF summary breaking down exactly what was covered, so nothing gets lost after the call ends.
