This is an early Maxon AD-900 Analog Delay with the desirable 2 x MN3005 chip configuration.

The AD-900 has that warm, musical analog repeat that sits behind your dry tone in a really natural way. It does short slapback beautifully, and when you stretch the delay time out, it gives you the soft, blooming trail that made this model so well-loved in the first place. The controls are simple and practical, so it is easy to dial in without overthinking it.

This unit is fully functional and comes with a genuine 12V center-positive adapter. Please note that it does not use the standard center-negative power supply that most guitar pedals use.
