This is an EQD reverb effects pedal. I haven't taken it outside once, and I think it's in good condition. Here is the product information: ■ Guitar Effects Pedal ■ Reverb ■ Controls 1. Attack: Sets the pre-delay. Adjustable from 30ms to 150ms. You can change the pitch of the effect sound with this knob when the reverb oscillates when the Dwell setting is high. 2. Dwell: Sets the length of the reverb. The longer it is, the thicker the sound becomes. Oscillation starts after the 3 o'clock position, and you can change the pitch of the oscillating effect sound by moving the Attack. 3. Depth: Sets the depth of the reverb. At the 12 o'clock position, the original sound and the effect sound are 50/50. After that, the effect sound is boosted. ■ Dimensions: 121 x 64 x 57 (mm) ■ Current Consumption: 86 mA ■ Input Impedance: 10 MOhm ■ Output Impedance: 1 kOhm Thank you for looking.
