I haven't used it much, so I'm putting it up for sale. It's famous because TAKUYA from the band JUDY AND MARY used it on tours and such. It's true bypass, so you're less likely to notice any sound quality degradation when bypassed. [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 make it easy to adjust the sound. It also has a direct bypass switch, so the sound quality won't be compromised even when the effect is turned off. [Durability] Rubber material is used on the bottom, making it non-slip and stable to set up. 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 looking. - Model Name: ADL2 - Brand: ARTEC - Function: Analog Delay - Controls: TIME, REPEAT, TONE, LEVEL - Power: 9V DC - Battery: 006P Thank you for looking.
