Just the Khozmo stepped attenuator
Quoted from Jeff :
The new more aggressive logrithmic taper that allows for less gain at the beginning. This has allowed us to offer the Milo without the restraint of an added attenuation circuit when purchasing the Milo with a Khozmo attenuator.
It might go back in a couple weeks for some other upgrades
I bought this unit used from a guy that went to the headtrip .
