Alesis M-EQ 230 Mid 90’s

Alesis M-EQ 230

This one has sat in a rack in my studio unused for years as can be seen from photos - it’s in almost unmarked condition as can be seen from the photos. I could only find one very minor scratch (see photo).

I used to use this as a feedback killer for live gigs which it did a great job of. I couldn’t find the power supply so bought a brand new one - everything works great on the quick test I ran on it.

I’m doing a spring clean of my equipment and as I no longer do live gigs this one needs to go.

The technical bit:
