Thank you for viewing. I purchased this unit used about 5 years ago, and I loved it because the sound was great. However, I'm selling it because I no longer have a use for it due to the introduction of other equipment. This unit has Velcro attached to the back, and it has scratches and dirt because it was frequently used in studios and live performances. I have confirmed that it works properly, but please refrain from purchasing if you are sensitive to the condition. 【Product Overview】 This Analog Delay is a very popular model as a guitar effects pedal. It provides a warm tone unique to analog, adding depth to your performance. 【Functionality】 The output, time, feedback, and level knobs allow for easy sound adjustment. It also has a direct bypass switch, so the sound quality will not be compromised even when the effect is turned off. 【Durability】 Rubber material is used on the bottom, allowing for non-slip and stable installation. The connection terminals are 1/4 inch jacks, compatible with a wide range of devices. - Model Name: Analog Delay - Output Knob: Yes - Time Knob: Yes - Feedback Knob: Yes - Level Knob: Yes - Direct Bypass Switch: Yes - Bottom Material: Rubber - Connection Terminals: 1/4 inch jack Thank you for viewing.
