Maxon AD9 Pro, analog bucket brigade delay, up to 450ms. Separate dry and effect outputs. Aside from the standard 3 knobs, it has a "dual/single" switch. Single gives you straight up delay. Dual gives you a tape echo multi-head effect.
Very clean and transparent for an analog delay, and it can do the self-oscillation thing.
Made in Japan, built like a tank. Takes a 9V battery or high current 9V output on your power supply (L6 on the Voodoo Lab Pedal Power 2+).
Mint condition. Velcro on the bottom comes off cleanly. Original rubber bottoms included. User manual included.
$155 shipped in the US. More if your'e outside the US, depending on country and service. MO, check, or Paypal. PM me for my info.
