Hola TB. I received a heavily modded EHX micro POG in a recent trade. I am not sure who did the mod or new paint job, nor did the guy I got it from. Works fine and tracks great, but I have redundancy with my synth and OC-2. The right switch is traditional and get the upper octave sound and then you can add sub with the left switch (so it seems). I honestly have not played with much it since i received it. Cool one off pedal in great shape, Would like to swap this for an easy to use, quality compressor, +cash ok. Note: bottom has some quality velcro but it is fur , not hook side. Asking $120 obo shipped conus. Thank you!
