The FREE THE TONE ARC-4 is the flagship routing controller in the ARC Series, redesigned to handle increasingly complex pedalboard systems. Building on its predecessor, it now allows naming of banks and presets, adds Setlist Mode for organising banks into performance-ready sequences, and supports MIDI clock and Bank Select for seamless integration with external sequencers.
At its core is FREE THE TONE’s HTS Circuit, maintaining consistent impedance at the input and output so your amp always receives a stable signal, regardless of effect combinations. This keeps bypassed and effected tones balanced and transparent.
The ARC-4 offers extensive MIDI control, sending multiple program and control change messages simultaneously, while remaining intuitive to use thanks to dual displays and a streamlined editing structure.
Designed for professional touring, it features widely spaced footswitches, stereo loop capability, boost and phase invert functions, moisture-protected LEDs, and a rugged chassis built to withstand stage use.
Includes original box and user manual. The included power supply is a US 110-240 (9v centre positive 500mA) so you can either buy a travel adapter or use your own pedal power supply.
