Electro Harmonix Q-Tron

Bass Envelope Filter / Auto Wah / Pedal
Since its foundation in 1968, the US manufacturer Electro Harmonix has always been very active when it comes to innovation in the field of guitar and bass effects pedals. For example, EHX developed the first analogue delay, the first flanger pedal, the first guitar synthesiser in pedal format... all building on the success of the Axis or Foxey Lady fuzz, which quickly became very popular thanks to the Stones and a certain Jimi Hendrix. With the Nano series, the manufacturer presents effect units that are space-saving and lightweight and are intended to fit on the often crowded pedalboards.

The Q-Tron is an envelope filter with switchable boost function and various filter modes. The current model has an extended frequency response and an improved signal-to-noise ratio and has thus made it onto the pedalboards of greats like Bootsy Collins or George Clinton.
