Two-Rock Studio Pro 35 Settings Guide
The Two-Rock Studio Pro 35 is a 35W boutique amp based on the Two-Rock Classic Reverb Signature platform — two 6L6 output tubes, hand-wired in California, with a single channel featuring Volume, Master, and a full EQ section with Deep and Bright switches. It is the definitive clean-and-push boutique platform: remarkable clean headroom, musical breakup when pushed, and the top-end clarity that John Mayer and Scott Henderson use as their primary amp platform.

Settings by Genre
Volume at 8 with Master at 5 — pushing the preamp hard to produce the Two-Rock signature pushed-clean/breaking-up character. Bright off (3) keeps the top end warm at high preamp gain. Mid at 7 provides the vocal, forward blues character. This is how Mayer uses his Two-Rock: preamp pushed, master moderate.
Low Volume for maximum clean headroom, higher Master for output level — the Two-Rock at Volume 4 is extraordinarily clean. Treble 4 and Bright off (2) rounds the top end for jazz clarity without harshness. Bass 6 adds warmth and fullness appropriate for jazz voicings.
Moderate Volume with Bright switch engaged (8) — the Two-Rock's bright switch adds the air and sparkle required for Telecaster country picking without a boost pedal. Bass 4 tightens the low end for articulate chicken-picking definition.
Artist Settings
Documented settings used by professional guitarists on this unit.
Mayer runs his Two-Rock Custom Reverb Signature with the preamp pushed significantly and the master at a moderate level, producing the edge-of-breakup tone that characterizes his tone on Where the Light Is and Battle Studies. He typically uses the Bright switch off and lets the preamp do the work.
Tips & Common Mistakes
- The Two-Rock responds dramatically differently to humbuckers vs. single coils — with humbuckers, reduce Volume by 1–2 points to achieve the same preamp character as single coils. The amp's front end is voiced specifically for the lower output of single-coil pickups at the Volume settings where the preamp becomes interesting.
