Didn't take it. Gonna just wait till pup is installed.
Lots of good info here... I'd agree about trying it out both with and without a mic at a practice, but as you know, adding audience to a venue changes a lot of things related to sound.
Just to serve as some other possible ideas (and to further define the rabbit hole), I've got both a Vic's pickup (Model C) installed (with an onboard pre-amp) and a separate mounted dynamic mic (Sennheiser e604) to provide a clear mic'ed feed...
I use the Vic's/pre-amp system when I'm playing with (or competing with, as the case may be) other amplified instruments or in an otherwise loud instrument situation (for example, keys, drums, horns, banjos, etc.), because a piezo based system tends to control feedback better than a mic. Worth mentioning though, arco through a piezo tends to be dramatically louder than pizz through a piezo, enough so that transitions between pizz and arco can be difficult while using a piezo pickup.
I use the mounted mic in volume-sensitive situations where I'm more concerned about the audience hearing tone and touch, or additionally where I might throw in a little arco. I'm primarily a pizz/slap player, but I'll add occasional arco for effect, and the mounted mic handles that well.
I can use either or both systems at the same time, although I usually only use the piezo or the mic. I can also use either or both to either my amps or to an FOH system, although again I usually only use the piezo system or the mic.
In my acoustic Gospel band, if we're playing with everyone else mic'ed, I always prefer to use my mounted mic. In the bluegrass/jazz/pop fusion band that I played with before Covid19, which featured loud
and mic'ed acoustic instruments, I used the piezo system.
Some highly respected folks here really like the mixed sound of a piezo and a mic. To me it's just an added complication, although I might occasionally use my piezo with a personal monitor amp on stage, while at the same time sending the clear mic feed to an FOH.
Lots of options... Different DBs may work differently, and different touch and technique may also work differently. There is no single standard. To some extent making selections is a matter of ratings, recommendations, personal preference, price, and trial-and-error.
