T-rex Moller 2, Overdrive with Boost

Essential information about the Møller 2 Overdrive pedal with boost

• Vintage overdrive with a warm and organic grain, designed to recreate the feel of a tube amp pushed just right.


• Independent clean boost up to +20 dB: ideal for cutting through the mix during solos or adding more punch to an already crunchy amp.


• Mix knob to precisely blend the clean and saturated signals, maintaining attack, definition, and dynamics.


• Bass Boost to enhance the low end depending on your guitar, pickups, and amp settings.

An overdrive born for the stage: the evolution of Knud Møller's signature sound

Originally developed for Danish guitarist Knud Møller, the Møller 2 carries the DNA of an "amp-like" overdrive: a natural, lively drive that follows your playing rather than crushing it. This second version improves the ergonomics and clarity of the controls while retaining the warm and dynamic character that made the model famous. The result: a pedal that works equally well as a main overdrive or as an "always-on" to thicken a clean tone.

For whom and for what: from blues to modern rock, with true touch control

The Møller 2 is aimed at guitarists who want an expressive overdrive capable of moving from a slight "edge of breakup" to a more present drive without losing pick response. It excels in blues, rock, pop, indie, and fusion, and proves very convincing in live contexts thanks to its dedicated boost, perfect for leads. In the studio, the Mix control helps preserve chord definition and attack grain even when increasing gain.

It integrates easily into a pedalboard: at the start of the chain to exploit the guitar's volume, or after a compressor/light boost to push the drive. On an already crunchy amp, it serves as a "second channel": more sustain, more presence, and an instant boost to cut through.

Controls, boost, and Bass Boost: a pedal designed for fine sculpting

At the heart of the Møller 2 is a simple yet highly effective set of controls. The Gain, Level, and Tone knobs adjust the amount of saturation, output level, and tonal balance. The highlight is the Mix: you blend the clean signal with the overdrive to keep precision in the lows and a clear attack, useful with humbuckers, lower tunings, or tight rhythms.

The Bass Boost adds an immediate option to reinforce low frequencies. This is particularly useful if your guitar or amp sounds a bit thin, or if you want a "wider" drive without overloading the gain. Finally, the boost on/off can be activated independently: you can use it alone as a clean boost or alongside the overdrive to switch to lead mode with more volume and authority.

The sound

The Møller 2 delivers an overdrive with a warm, organic, and very responsive texture. It respects nuances: playing lightly keeps the sound open and dynamic; playing harder naturally thickens the saturation. The Mix provides a very musical sense of "relief": chords retain air and definition, and notes stand out without becoming harsh. With the boost, you easily achieve a more present, firmer solo sound without changing the drive's balance or losing the guitar's character.
