OK, I got mine. Took about 6 days to get here from time of order - not too bad.
A couple of notes:
I just recently got a couple of boost pedals - Coppersound Gravity Bomb boosts, that have LED's that.. will give you a tan on stage. As the one I have on a board is next to a tuner, it's hard to see the tuner display with all the light from the boost's LED. Other than that, those are good boosts - nice and quiet.
Why do I bring this up? The led's on the Genzler are sensibly illuminated. They won't burn you eyes out. The "off" led is fine. The "on" LED is a bit dimmer than I'd like - it's fine on axis, but if you're not standing over your pedalboard, it's pretty dim off axis. The pedal can be subtle enough that a visual indication of on or off is a bit more critical than many pedals. Some room for improvement.
It raises the noise floor some (expected in a gain pedal), and the character of the added noise varies with the filter controls - again, that makes sense.
How does it sound? It's great at subtle drive sounds. This is the closest pedal yet to the sound in my head, which is the "straining but not clipping amp" kind of thing. Yes, it can do over the top, but with the drive sensitivity switch in "low" position, you can move knobs a great deal, and things will change some, but it sounds pretty good over a wide range of settings.
The 4 modes (gears) do change the sound, but not over a huge range - a lot of things about this pedal, including this, seem like they're designed for me - there's enough range, but it seems to explore the range of sounds I want, and not a whole lot more - it does "usable" very well, and avoids the "wacky" area. I expected to like one, maybe two of the "gears", and...I think I could find regular use for 3 of them, and occasional use for the 4th.
So, my summation is - this is a great pedal for those of us who want an "amp-like" overdrive that can be dialed down to a subtle effect, and that has some variety of usable sounds on tap.. If you're looking for a Muff/broken sound, this ain't it.
Now for the biggest issue. My Pork and Pickle fits on my main board without any space squeezing. Getting this one on there in its place is gonna take some finessing of things.
