Vahlbruch FX is a one-man boutique pedal company based in Springe, Germany, founded by Dr. Henning Vahlbruch, a physicist at the Max Planck Institute for Gravitational Physics (Albert Einstein Institute). Every pedal in the lineup is designed, assembled, and tested entirely by hand in Germany, with no mass production or offshore manufacturing.

The brand is known for its proprietary MagTraB (Magnetic Transducer Button) switching system, which uses a magnet-and-sensor design paired with a microcontroller and gold-plated relay contacts to achieve silent, click-free true-bypass switching with a virtually unlimited lifespan. The product range spans overdrive, delay, modulation, dynamics, and utility pedals. Flagship models include the Kaluna II High Voltage Tube Drive, which runs an ECC83/12AX7 tube at 250 volts with a three-band active EQ; the SpaceTime Tap analog delay with tap tempo and selectable delay divisions; the Quantum opto-compressor; the 6-Phi-4 JFET phaser; the BBQ and BBQ-XL buffer/booster/EQ combinations; the OptoTrem optical tremolo; the Pipeline reverb; and the Xroads amp/tuner switching pedal.

Dr. Vahlbruch brings an unusual background to pedal building — his academic work focuses on squeezed states of light for reducing quantum noise in gravitational wave observatories, and that precision-engineering mindset carries over into his pedal designs, which emphasize ultra-low noise floors and meticulous component selection.

Vahlbruch has 6 products cataloged on Equipboard, including Overdrive Effects Pedals, Chorus Effects Pedals, and Compressor Effects Pedals. Their gear is featured by 2 artists, with the strongest followings in Rock. Notable users include Tricot and NIgel Tufnel.
