It's in excellent condition, practically new, having only been test-fired to check its functionality. An effector for manipulating the attack. Produces sounds reminiscent of a violin, guitar synth, or Kurt Rosenwinkel. I believe this size with these features is truly unique. - Model Name: Pico Attack Decay - Included: User manual, power adapter, box - Function: Tape reverse simulator - Control Knobs: VOL, SENS, ATTACK, DECAY Thank you for viewing. I will also check the operation before shipping, so I cannot respond to any problems during or after shipping. Thank you for your understanding.
