I've had loads of glitch/synth/bit crusher pedals, and as far as crushers or sound manglers, or any of the pedals in the same category with the BitMap2 and the Meris Ottobit, I have found the for what I PERSONALLY am looking for ( sure John Davis/Nerve - but the ability to make new sounds on the fly as well ) that the Bitmap2 has won the contest. I have had the Meris Ottobit for quite a while and not only is it a little more limited, is also much more touchy. Sound spikes and lows out of nowhere, inconsistent volume, and I found using it to be a bit of a pain. I might use one again next to my laptop, where I can control it better, and don't get me wrong, Meris makes some of the coolest poopie out there. I just find the Bitmap2 to be much more what I'm looking for. For that matter, If I'm using a small rig and just need that John Davis Nerve sound, I'll usually just use the Fredric audio Bugcrusher. You can do a TON of cool stuff with either an OC-2 or Really nice synth pedal, the Bitmap2 and a great envelope filter. Anyway, my 2 cents.
