Get ready to send it with the Postman. This pedal is a versatile and easy to dial envelope filter. Open it up for an aggressively sharp sweep, or dial it back for a softer bubbly swell. Flip the swing switch for a reverse envelope sound unlike anything you've ever heard. Now with an added distortion circuit and tone filter control. All of this in one neat little package. Get your dream tone signed, sealed, and delivered with the Postman.
