Had to bump this. Playing through my headphones tonight I realized there was a subtle, yet very much there, presence of the drive knob with the Scrambler turned off. The only reason I noticed was because I was playing it with my usual configuration (Keeley>BarbershopME>SCR) and it seemed a bit dirtier sounding than usual. After tweaking some settings on the other pedals and starting to think it was my headphones starting to crap out, I dialed back the drive knob on the Scrambler and whattaya know...a VERY audible (though slight) impact resulting a a touch more dirt. I can quite clearly hear it raise the dirt (again, it's a very subtle dirt, but it's there) and lower it with the knob. It seems to roll off/boost at about 10 o'clock. It's also not dependent on where the blend is set. I couldn't find anything in the manual. Is this normal? Anyone else notice this?
I'm trying mine out through a pair of Sennheiser HD202 cans right now. Tried it with all 3 of my basses, and so far, I don't think I'm hearing a difference.
