Two Rock Studio Signature 1x12 Combo

$2,999.00
Used

The Interstellar Tone Traveler holds a short list of amplifier builders whose instruments represent the absolute ceiling of American hand-built quality — and Two Rock sits near the top of it without debate. The Studio Signature is the latest generation of their acclaimed 35-watt single-channel platform, descended directly from the Studio Pro 35, and it arrives with the build refinements and voicing upgrades that Two Rock has developed over years of continued iteration. The new aluminum chassis, anodized in black with silver knobs and matched against a black Bronco cab and silver grille, gives this amp a commanding, modern aesthetic that looks as serious as it performs. This is a pristine used example in excellent condition — shows virtually no signs of play, functions and sounds flawlessly, and includes the custom slip cover. For players who've been waiting to get into a Two Rock at a price below new, this is the moment.
The Studio Signature's design philosophy is the same one that has made Two Rock the first choice for discerning pedal platform players for decades: a clean, 6L6-powered circuit with enormous headroom and a natural, responsive character that makes everything you put in front of it sound like the best version of itself. Two 6L6 power tubes drive 35 watts through a custom Two Rock 12-65B speaker specifically voiced to complement the amp's character, with four 12AX7 and one 12AT7 in the preamp chain and an all-tube reverb circuit that adds depth without cloudiness. The 3-position Gain Structure switch — first introduced on the Classic Reverb Signature — gives you three distinct preamp personalities from a single channel, expanding the amp's range dramatically without adding complexity. Bright, Mid, and Deep toggle switches provide further voicing control, the Presence and Master give global authority over the final shape and output level, and a reverb send control on the rear panel joins the reverb return on the front for flexible reverb management in any routing configuration. A passive effects loop and 4/8/16-ohm speaker output switching round out a package built for the player who refuses to compromise on the foundation of their tone.
