Whats inside

Every part of this experience exists because of this masterclass moment.
Nothing here is accidental. 

​Gristle ST Guitar With Case - Signed 
Avocado 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.

​Gristle King Pedal
Signature Clean Boost & Overdrive 

The Gristle King delivers articulate clean boost, touch-sensitive overdrive, and plenty of attitude when pushed. Designed to respond to your hands and your guitar, it moves seamlessly from subtle grit to full-bodied drive without losing clarity.

​​Lil Heat Pedal
​A Compact overdrive built to deliver rich, amp-like tone with extra gain on tap.

Based on Tone City’s beloved Sweet Cream circuit, the Lil Heat adds a custom HEAT boost stage personally requested by Greg to kick things into higher gear. The result is added punch, sustain, and saturation while staying musical and responsive.
