Descent adds an ambient texture to your sound. This pedal has three modes: Hall, Reverse, and Shimmer. In each mode, you can add sounds an octave above or below the effect sound. Hall mode provides classic reverb effects such as the reverberation of a small room or hall. Reverse mode provides a reverse effect with a pre-delay time control. In Shimmer mode, the octaver function is featured, allowing you to freely change the mix of dry signal, one octave below, and one octave above to create a spectacular sound. Descent's eight knobs let you achieve any reverb sound you want. You can also connect an external switch to the Fav input to turn effects on/off and save presets. If your pedal board is full of pedals, place the Descent at the back of your board and connect a small SPST switch. By placing the switch at the front of the board, you can make better use of valuable space. The Fav input uses a TRS cable. Descent also supports expression pedals. The expression pedal allows you to set the upper and lower limits for each parameter.
