Purchased this about half a year ago and simply used it for practicing.
Worked great, for what i required it to do.
Disclaimer:.
Missing out on the nob for the volume level on 15/16.
A few of these are also a little bent. Do all work.
The primary outputs never worked on this - Sub outs do work (which is what I used).
Might be a simple repair - I don't have adequate time to attempt and repair it.
Works terrific, other than the items listed above.
E-mail for more details, if needed.
