It does not behave like a "normal" fuzz when you roll your volume down....but that works just fine for me

The resulting buzz does sound a bit like a slightly overdriven non-master volume amp (or a master volume's clean channel fully cranked)

i don't have a pedal worth that much to compare it with, but alone this fuzz pedal does the job, quite well in fact.

It's a reliable fuzz that does the job

Still, throughout most of its gain and volume range, BOOST does a good job of staying clean
