I used mine a lot over the weekend, still into the power section only of my Tecamp and then into a couple of Barefaced One10.
It's very impressive. I started with the recommended Dug settings but then backed off the bass, the compression and the drive, but would up the mids to 12 o'clock.
I;m getting a thick, chewy half clean / half dirty sort of sound that reduces the drive when I play gently and then gets gritty when I did in. Sounds superb - it's a great rock sound.
I doubt I'll be using it for jazz stuff, so I'm next I'm going to try to use it in front of the amp and see if I can make it sound the same when activated but leave me with a more jazz sound when I turn it off completely.
And I ran out of time to see what happens when I stack it with my DG and EBS drives and fuzzes. Soon.....
