Played with a blackstone tonight...could not connect

[jamminoutloud1]

Hey guys,
I played through a fender deville amp tonight at a gig with a blackstone pedal tonight.
I felt like there was very little sustain or dynamics, and a bit fizzy at times...it was the first time I used it on a gig.
I really wanted to love it, but could not get it right. On the red channel I had the gain at about 5:00 or 4:30, and the volume at around 8:00. On the brown channel I had the gain at around 4:00 and the volume at around 9:00.

I just was not getting those juicy leads that I was expecting. I played with a highway one telecaster w/ dimarzio noiseless in the bridge and 52' reiusse in the neck. I also had a tubescreamer, which I tried stacking and it did not seem to really work. I had the blackstone first in the chain as well.
Any advice? I would prefer not to open this thing up if it can be avoided.
