I had several times in the past the opportunity to play on Tone King amps (www.toneking.com): they sound great. That's why I was very happy to meet Mark Bartel who is the tone guru at Tone King during the NAMM show.
- His first guitar
- His best and worst memories of past editions of the NAMM show
- How he became an amp builder
- His method to develop a new amp
- What's left to invent in the tube amp world
