Variable Mu Tube Compressor
for Silver Bullet mk2
We intend to make a dedicated Mojo Module host and would love your design input. Take the survey.
Overview
Locomotive Audio and Louder Than Liftoff are proud to announce a collaboration on an expansion module for the Silver Bullet mk2: the Fairi-Mu by Locomotive Audio. Fairi-mu is a stereo vari-mu tube compressor inspired by the vintage classics. It draws on the heritage of Locomotive Audio’s acclaimed 14B and WT-COMP compressor designs to deliver smooth, euphonic compression to mixes and individual tracks. When the Silver Bullet was initially conceived back in 2014 it had always been a dream to get some real tube mojo into the signal flow of the unit. When the mk2 version was launched in 2021 for the mk2 version, we knew our friends at Locomotive Audio were the right partners to bring this valve vision to life.
Features
- Vari-mu compression when sidechain is enabled
- Tube & transformer saturation when sidechain is bypassed
- Attack: 0.7, 10, 40 ms – selectable by jumper
- Release: 150, 300, 600 ms – selectable by jumper
- Ratio: 1:1 to 3:1 – varies with compression
- Threshold and Output Gain – adjustable via trimmers
- Sidechain High Pass Filter (HPF): off, 100, 200 Hz – selectable by jumper
- Stereo Link or Dual Mono sidechain
- 12AU7 tubes
- Custom wound American-made transformers
Fully assembled and tested by Locomotive Audio.
Silver Bullet mk2 must be purchased separately. This module may be purchased as an add-on for your Silver Bullet mk2 or chosen as an option when purchasing a new one.

There are intuitive controls for drive (C-DRV) and wet/dry mix (C-MIX) on the front panel for the MOJO C expansion slot.
NERDY DETAILS
PREMIUM COMPONENTS & BUILD QUALITY
We chose every component in our Mojo modules by ear for maximum mojo and its sonic synergy with the rest of the circuit. Our meticulous development process involved both empirical measurement and real-world studio use to validate the design. We also leveraged what we learned designing and building our other products. In this design you will find high end parts from Nichicon, Panasonic, Vishay, Susumu, Wima, and TI. All audio path resistors are 0.5% or 0.1% thin film types for low distortion and noise. Where applicable, some modules features custom American wound transformers and our very own discrete op amp. Our PCBs use high temperature Tg 170 material for long-term reliability. The entire assembly is RoHS compliant (lead free).
