What's wrong with the multi-tap delay?

I can’t get a clean delay out if; only crunchy and mid-rangey.

All FX are bypassed (loop, tap and post), saturation is @ 0%, the filters are off with no damping applied.

All I get is turd-cake vibraphone out of the delays.

Is there a built in, hidden junk distortion?

My guess would be you are overdriving the input level.
