The MXR Booster Mini (M293) is a highly popular, compact guitar effects pedal manufactured by Jim Dunlop. It functions as a "two-in-one" tone enhancer by combining the circuitry of two legendary MXR pedals into a single, pedalboard-friendly mini housing.
Key Features & Design
- The Sonic Engine: It pairs the vintage, musical warmth of the Echoplex Preamp (EP-3 circuit) with the clean, raw driving power of the classic MXR Micro Amp.
- Massive Output: The pedal delivers up to +25dB of clean boost, allowing you to push a tube amplifier into natural overdrive or slice through a heavy live mix during guitar solos.
- True Bypass: It features a true bypass footswitch to ensure your core guitar tone remains completely unaltered when the pedal is switched off.
Interface & Controls
The pedal is deceptively simple on the outside but offers deep customisation under the hood:
- Volume Control: A master knob on the face of the pedal that dictates the overall output boost of the Micro Amp stage.
- Tone Control: A high-cut knob on the face that rolls off unwanted high-frequency harshness, letting you smoothen out bright single-coil pickups or harsh amplifiers.
- Internal Echoplex Trimpot: An internal level control located inside the pedal housing (accessible by removing the bottom plate). This adjusts the gain and coloration of the Echoplex Preamp stage, allowing you to add subtle grit, compression, and harmonic fatness before the signal hits the volume stage.
Specifications & Power
- Enclosure: Built from heavy-duty brushed metal in a lightweight, space-saving mini format.
- Power Requirements: Operates via a standard 9-volt DC power supply (such as the Dunlop ECB003 or Iso-Brick series) drawing roughly 12.5 mA. It does not accept internal batteries due to its mini size.
- Input/Output: Standard 1/4-inch mono jacks.
Use Cases
The MXR Booster Mini can be placed at different positions in your signal chain depending on your goals:
- Front of the Board: Place it before your overdrive and fuzz pedals to use the Echoplex circuit to add unique compression and push your dirt pedals harder.
- End of the Chain: Place it after your delays and reverbs to act as a pure volume boost that lifts your overall volume for solos while fattening your tone.
