I bought this in the 80's and it's one of those pieces of. Equipment you just hold to because it can always come in handy. I originally bought it as a pre amp for bass amp, then went on to use it for guitar and it's last job was a pre amp for Vocals for our practice studio. Anyway it's been sitting in my closet for 20 years.
Time to let it go. I recently tested it works great a little.
Static on the EQ switch from channel to channel only when switching it not while playing. Check my future auctions for good deals.
