TMH007B — MXR Black Double Down Pedal

The TMH007B is the MXR Black Double Down Pedal, a limited edition collaboration between MXR and Third Man Hardware. Born from the creative partnership of two iconic names in the world of music, this pedal represents a convergence of engineering precision and the raw, uncompromising spirit that Third Man Hardware is known for. It is a purpose-built tool for the working guitarist — one that solves a real-world problem with elegant, no-nonsense circuitry. As a sold-out limited edition, the TMH007B occupies a rare space in any guitarist's collection: both a functional powerhouse and a coveted piece of hardware history.

Dual-Circuit Boost Architecture

The Double Down Pedal combines two separate MXR Micro Amp circuits into a single enclosure, allowing players to heat up two separate signal chains with the classic Micro Amp boost. This foundational design decision is what makes the TMH007B genuinely distinctive. Rather than simply duplicating a signal, it gives each output its own independent amplification pathway, rooted in the time-tested Micro Amp topology that guitarists have relied on for decades. A single input jack splits the signal to two separate outputs, each equipped with its own Gain control capable of delivering up to +26dB of signal-boosting power. That's a substantial amount of headroom, giving players everything from a subtle presence lift to a full, saturating push.

Stereo Control and Phase Manipulation

On the left side of the housing, a Phase switch adds a pronounced stereophonic effect by inverting the phase of the second output signal. This feature opens up a dimension of sonic depth that goes well beyond standard boosting — creating a wide, immersive stereo spread that can dramatically transform a live or studio rig. A yellow LED indicates when the Phase switch is engaged, making it easy to monitor your signal chain status at a glance, even under dim stage lighting. Whether running into two separate amplifiers or a stereo effects setup, the phase inversion capability gives the TMH007B a creative versatility that few boost pedals can match.

Bypass Flexibility for Every Player

On the right side of the pedal, a Buffer switch allows players to choose between true bypass — for the purists — and buffered bypass switching, which keeps your sound intact when driving two signal chains. This thoughtful dual-bypass option acknowledges the ongoing debate in the guitar community and simply offers both solutions in one unit. A yellow LED indicates when buffered bypass is active, while a single footswitch toggles the entire effect on or off. For a gigging guitarist running long cable runs or complex pedalboards, buffered bypass ensures signal integrity across both outputs without compromise — while true bypass satisfies those who want absolute transparency when the pedal is disengaged.

Why Our Gear Experts Appreciate the TMH007B

Our gear experts love the TMH007B because it solves a practical problem with professional-grade engineering. The ability to drive two separate signal chains simultaneously — each with independent gain control — is a genuine game-changer for players running stereo rigs or dual amplifier setups. The phase inversion adds real creative depth, while the choice between true and buffered bypass respects every player's preference. It's the perfect booster for gigging guitar players, and its limited-edition status makes it all the more treasured.
