About This Item
Description
An overdrive plus dedicated clean boost in one enclosure — the Moller 2 delivers T-Rex's signature warm, transparent overdrive with a switchable boost that pushes leads over the top without changing your amp's character.
Which T-Rex Moller is this?
The Moller 2 is the current-production version of T-Rex's most popular overdrive. It keeps the original's warm, dynamic overdrive voice and adds a refined boost circuit, a Bright switch for extra top-end presence, and modern build quality — all hand-assembled in Denmark.
Why guitarists choose this pedal
- Two independent stages — Overdrive plus dedicated Clean Boost — controlled by separate footswitches.
- Warm, valve-like breakup that tracks your picking dynamics and volume-knob rolloff.
- Bright switch adds shimmering top end for single-coils and darker humbuckers.
- Clean Boost stage is voiced to push a tube amp into further breakup rather than just add sterile volume.
- 9 V DC or 9 V battery — side-mounted jacks save pedalboard space.
Controls and switches
- Level (Overdrive) — output volume of the overdrive stage.
- Gain — how hard the overdrive stage clips.
- Bass — low-frequency shelf.
- Treble — high-frequency shelf.
- Boost (Clean Boost level) — sets how much clean gain the boost adds.
- Bright switch — engages a treble lift for sparklier highs.
- Footswitch OD — engages the overdrive stage.
- Footswitch Boost — engages the clean boost stage.
Power and pedalboard compatibility
- 9 V DC only, negative-center, standard 2.1 mm barrel (accepts 8.5–12.5 V DC).
- Current draw ~16 mA — trivial load on any isolated supply.
- 9 V battery capable — battery door on the underside.
- True bypass — sits anywhere in the chain, works especially well early (guitar → tuner → Moller 2 → modulation → delay/reverb → amp).

FAQ
Is the Moller 2 an amp-in-a-box style overdrive?
It leans into transparent, dynamic overdrive rather than voicing a specific amp. Think Tube Screamer-adjacent warmth with a wider EQ range and less mid-hump.
Can I use the boost on its own for a cleaner solo bump?
Yes — the two footswitches are independent, so you can run only the clean boost, only the overdrive, or both stacked.
Does the Bright switch add gain?
No, it lifts the treble EQ. Useful for darker humbuckers or on stage under bright lights.
What order should I stack the boost and OD?
Internally the boost sits after the overdrive — engaging boost while OD is on pushes your amp harder without adding extra distortion coloration.
Battery life?
Around 15–20 hours from a good 9 V alkaline. Unplug the input jack when not in use to avoid draining the battery.
Warranty?
2-year manufacturer warranty.
