Keeley DELAY WORKSTATION. This is an effects unit that combines delay and reverb. It's compact, easy to use, and has a chic, sophisticated design. While there are many delay and reverb pedals on the market, currently, only Keeley offers a unit that combines both and allows each to be used independently with multiple functions. Moreover, it's discontinued. It only requires one power supply, making it very convenient. Its small size also allows it to fit neatly on a pedalboard. Recent delay and reverb pedals tend to be multi-functional but large, leading to oversized pedalboards, which can be a hassle for users. This unit avoids that issue. The sound quality is, as expected from Keeley, excellent and suitable for various genres. It's currently only available used, making it very valuable. Please consider it. - Model Name: DELAY WORKSTATION - Functions: Delay, Reverb - Control Knobs: DELAY SELECT, BLEND, TIME, FEEDBACK, MORPH, PRE - Input/Output Jacks: 5 x 1/4 inch jacks - Footswitches: DELAY, TAP, REVERB
