The Mooer Free Step brings together a vintage analogue Wah Wah and a very flexible volume control into one small, strong and comfortable expression pedal. In Wah mode you can activate the effect at the touch of your sole using MOOER's innovative foot sensing circuit, or you canoperate it using the more traditional 'toe down' footswitch method. Allowing you to leave it cocked in any position you like as a filter. The custom inductor can be dialed in to your favorite Wah tone using the very convenient Q Range dial on the side of the pedal. In Volume mode the Free Step will stay faithful in retaining every nuance and detail of your tone. It's smooth, seamless transition makes it a joy to use in any rig to control your volume. The heel down (minimum volume) can be easily adjusted and set anywhere in the range of 0%-50% using the handy min. vol. dial on the side of the pedal. All of this is wrapped up into an incredibly strong and sturdy expression pedal which will survive for years and years of even the roughest use.
