I've owned this beast since early 2007, when I was but a foolish gui****. I actually sold it and then bought it back. It belonged to my cousin for awhile and was then re-appropriated for a friend, and has now been reassigned to bass. First off, it is a monster. And I mean this in the best way possible. It does a good job (to my earplug-filled ears) of making a distorted sound without getting "fizzy". Your Results May Vary, but with a Laney RBH800 driving a 4x10 and 1x15, I detected minimal fizz. This was also with a heavy mid scoop. Having the "Top Boost" on actually makes it sound a little edgier i.e better on my amp with my setting (which I am too lazy to go look at right now because it is 12:35 AM. I'll make not of them tomorrow). Secondly, the notes are pretty clear. Sure, the low B on my five string is boomy, and I had to actually use the tone control (!!!!!!!!!!) on my bass to remove some of the highs. Methinks those rocking P's or slightly favoring the Neck on their J's might be liking this pedal (if a rude sound is what you are after. I will say that EHX can make rude and over-the-top pedals). Also, turning off the "Top Boost" will remove lots of the treble-y scream but re-arranging the knobs will be in order. That's the only caveat I have right now at this stage of testing. Expect a full-er video review in my Distortion Megatest Thread. But back to notes, they sound pretty good. I can sorta play the intro to Om's Flight Of The Eagle and still sound good, sans Rick and wall of green Matamp clones. Thirdly and Finally, I am so far impressed. I can get that high pitched squeal feedback heard on Orphan, Lighthing Bolt, Om, and others' tracks, something I've had trouble getting elsewhere. My luck with the Metal Zone has been limited, so this is a refreshing and less fizzy-sounding (to my damaged and now protected ears) change. That's all for now. More later as time progressed.
