Mackie 24x8

Audio Proz Inv #: 40711

Mackie 24x8x2 (24 channel, 8 bus) mixing console. Needs Cleaning - controls scratchy and intermittent. This type of service would require a decent skilled tech to pull all the knobs, dismantle the large main board, and clean the controls with a recommended cleaner and reassemble. Our testing here has shown that 99% of the problems with this board are cleaning problems. It would probably take 3-4 hours to service. We would charge $300 to do the work ourselves.
