The tuner works fine
The compressor works but mine would make a clicking sound when I hit the first note after a silent part. I found that using the pad helps remedy that (I am using passive basses).
The preamp sounds pretty good (in VT mode). You can set the two channels up for either a boost or one for overdrive. The downside is that they share the EQ.
I don't use the octaver or fuzz.
The chorus sounds OK, but not great.
The Bite switch is tricky. It's way too bright, but it does add clarity. I use it by bringing down the tone on my bass. It gives you another variation of tone.
I have replaced it with a Zoom B6 that is far superior to the BFRv2. I guess one of the advantages of the BFR is that it fits in a bass case. I wish it could run on phantom power.
Great points! Which reminded me that the Pad seems to suck the tone out of my bass. I have a P-bass that is very loud, and I tried it with the Pad on. Volume was tamed but it got muddy.
