Electro Harmonix Mainframe Bit Crusher

Disclaimer: I am using this with synths, not guitars.
I like the sound and appreciate the many adjustment options of this pedal. The sample rate effect sounds more interesting to me than the bit crushing, which surprised me a bit. Glad to have both though, and the filter is a plus.

The pots are quite tight, so even though they are very close together, it is possible to change one value without inadvertently move a nearby pot. Big fingers will have difficulties though, and I imagine using it in a dark scene setting, placed on the ground as intended, will make it near impossible to make any on-the-fly adjustments. The preset button may help in this situation. On a desk it is tolerable though.

Essentially this box has 3 features: bit crush, sample rate reduction, and filter. I do find it to be overpriced though. They could at least have made it stereo at this price point.
