For sale is an ADA MP-1 Guitar Tube Preamp, one of the most iconic rack preamps of the late '80s and early '90s, renowned for its distinctive tube tone and versatility.

The unit has been checked by a technician in the past and is generally in working condition. However, it has a slight background hum that is noticeable depending on the selected sound. In the high-gain/distortion modes, the hum is much less apparent. It would certainly benefit from some additional attention by someone experienced with vintage electronics.

Despite this issue, the MP-1 still delivers the classic ADA tone it is famous for, from sparkling clean sounds to rich, saturated high-gain tones.

Modifications / Notes:

• Equipped with a battery mod, allowing the memory backup battery to be replaced easily in the future.
• The original input jack has been replaced.
• The original Output Level knob is missing. The control itself still functions, but the original knob is no longer present.
• Cosmetically, the unit shows signs of age and use, but it still looks great in a rack.
