Digital reverb/delay pedal with a variety of effects. I have confirmed that all 11 modes are working, but I cannot answer detailed questions about the sound quality (I'm not very familiar with it & I can't produce sound because I bought a mini amp first). No claims or returns accepted. Please consider this if you agree to purchase it as-is. Thank you. I don't remember using it much, so I think it's in good condition! - Model: RV-3 - Function: Digital Reverb/Delay - Output: OUTPUT A (MONO), OUTPUT B - Modes: DELAY, REVERB, 8 types of effects - Controls: D.TIME, F.BACK, EFX, DIR, CHECK - Input Terminals: INPUT, OUTPUT A, OUTPUT B Thank you for viewing.
