Working AD-900 analog delay (early model) with adapter MAXON's "AD-900" used Matsushita-made BBD components, but the AD-900 was discontinued when these BBD components were discontinued. It will become valuable from now on. The delay time is "600ms," which is quite a high-spec delay for an analog delay using BBD components. Purchased new in the late 90s and used for 2-3 years, then stored. Early model with two MN3005 BBDs, operation confirmed. There are minor scratches, but no dents or significant paint peeling. The rubber on the bottom is in good condition with little wear. During testing, there was no crackling or noise from the footswitch or knobs. The entire unit has been cleaned with alcohol. The serial number sticker has peeled off. This is an effect pedal with a soft, smooth, and pleasant sound, rather than an extreme delay effect, so it seems to fit those looking for a natural-sounding delay. The item is a set of the main unit and the genuine adapter. It will be wrapped in bubble wrap and shipped in a cardboard box. I am also listing other vintage effectors and analog synthesizers. #analogdelay #delay #effector #maxon
