Can't see any ALPS logo. If it's on the bottom I can't tell because they're soldered in obviously. No other signs to tell what kind they are
e: so everything seems good so far, installation was quite easy (fiddling with the ribbon and the connectors was the hardest part).
the black V2 jog wheel looks fantastic and has a very nice feel to it. only downside is the wobble that is mentioned on the product page. I've tried to fit it on every which way and it still doesn't sit perfectly but it's not a big deal
buttons feel nice, a bit more snappy and not as wobbly as the akai ones (I did buy the mpc button kit also)
don't really have the time to give everything a more thorough test but time will tell with the tact switches. will report back if anything goes wrong
oh and on an unrelated note, do not buy these if you have a 2500: http://www.mpcstuff.com/silver-top-blac ... -maschine/
they're not shaped to fit the rotary encoders so they're extremely loose and don't do what they're supposed to do
