This is a used item that has been tested and confirmed to be working. Matthews Effects / The Traveler Matthews Effects / The Traveler The Matthews Effects The Traveler was developed with the goal of being the ultimate reverb pedal for all musicians. It's compact and multi-functional, allowing you to select from three types of reverb algorithms: MOD, SHIMMER, and VINTAGE. These three original algorithms bring infinite creative possibilities to your sound. You can easily control the tone with three knobs. The MIX knob blends the dry and wet signals, the M knob controls unique functions for each algorithm, and FEEDBACK adjusts the length of the reverb. From subtle reverb to amazing soundscapes, The Traveler can create a variety of reverb sounds. Furthermore, holding down the footswitch activates the HOLD function, which sets the FEEDBACK to its maximum setting while pressed. Releasing the footswitch returns to the original settings. Thank you for viewing.
