Description
Matamp was founded by electronic engineer Mat Mathias in the early 1960s. In 1968, he partnered with Cliff Cooper, who used Mathias’s circuit designs to launch the Orange Amplifier brand. Early on, the two shared co-branding as Orange/Matamp—often shortened to “ORMAT”—before parting ways in 1971 to pursue separate directions. From then on, each brand marketed similar designs, though with their own distinctions. 

This early-1970s Matamp closely resembles the late-1960s ORMAT designs. It should be noted the amp has been modified, with input matrix “Drive” control disabled, utilizing the knob as a pre–phase inverter drive control, effectively serving as a master volume. This change is common on Orange OR80/120 models from the mid-1970s, helping to tame their considerable volume. Fortunately, it still delivers the unmistakable Matamp roar! A small sticker was added to the front #2 input, likely to indicate it as the high gain input, which is the opposite of most amps.

The electrolytic caps have been replaced, along with a couple of resistors, but otherwise the circuit remains original. See internal photos for further details.
*When using Affirm, we charge an additional 3.5% fee on the total at checkout. The majority of our instruments are consignment, where CVG keeps a small percentage of each sale. To be able to cover the additional costs required to offer financing, we have to include a higher fee to the customer. The 3.5% fee will be included in and spread across your Affirm payments.
