Pearl AD-33 Analog Delay early 80's MN3005 BBD s/n 857007 Japan in excellent condition with box. Thoroughly tested and in perfect working order.

The Pearl AD-33 was an analog delay released in the 1980's by Pearl and is part of the Sound Choice series. Pearl pedals were built in Japan by a company called KLM (much like Ibanez pedals were built by Maxon) and were engineered to include some very innovative features for this era.

Vintage Japan Pearl AD-33 analog delay with MN3005 BBD. Dual time+feedback settings to switch between on the fly.  A bit like having two early model Boss DM-2's side by side. The 18V circuit allows for greater headroom, giving a clearer signal and delay repeats than standard 9V vintage analog delay pedals.

Works perfect and in overall good physical condition with some paint aging/wear as pictured. Takes an 18V DC power supply (2.1mm barrel plug, center negative) or 2 x 9V batteries.  So it works with most multi-output (brick-style) power supply units;
