Hello!
I've managed to get information from Seymour Duncan on the differences between the Vise Grip and Studio Bass

Hi,
There are a few differences between the Vise Grip and the Studio Bass Compressor.
The bass model allows the player to bypass lows, mids or all frequencies. We did not find the high frequency bypassing of the Vise Grip to be useful, or even desirable, for bass.
The range of compression ratio and make-up gain was limited for the bass model. We found the extreme setting to be unpractical, there was too much pumping at bass frequencies.
The attack and release were slowed for bass. Too fast an attack, again, caused pumping and too fast a release caused excessive distortion as the compressor tried to follow the lower frequency waves. It starts to interpret them as changes in level rather than just the longer time constant of low frequencies.
Essentially, the Sustain knob on the Vise Grip and the Compression knob on the Studio Bass Compressor do the same thing, working in conjuction with the Attack control to provide sustain. Due to the different frequency bands, you may notice more "pumping" from a bass signal at higher compression settings than you would with the Vise Grip on guitar."
Hope this helps someone, eventually.
