The Pedal I/O 1U system enables the modular synthesist to interact with the impressive assortment of delays, choruses, flangers, phasers, fuzz boxes, tremolos, wah-wahs, amp simulators, compressors and pitch shifter pedals available to guitarists. Conversely, it also grants guitarists access to the myriad filters, ring mods, wavefolders and — most importantly — the near infinite CV modulation delights inherent in eurorack. The Pedal I/O is more than just a simple level shifter — it’s also an impedance converter, which provides proper drive and loading for any FX pedals or instruments you connect.
