Home ( Practicing ), At lessons, at public recitals, playing with a friend.
The recitals can be sort of loud, since my instructor and his former student are bass players, and the drummer doesn't have volume control.
If it’s mostly low noise environments the K&K mini or Shatten HFN passives are good and natural sounding. Both will require some external EQ. I’ve installed a K&K and it’s not bad to do. The K&K gets glued in under the bridge, but the schatten can be taped so is easier to remove. Both need the endpin holes drilled out, unless you use a tapastring vintage 1/8 jack. If needed, you can buy a $10 rubber soundhole feedback buster for the occasions where you might need it. If you end up doing more gigs where it’s noisy these passive systems may not be the best choice. If your EQ can also notch out the bad frequencies that will help.
The Seymour Woody XL is a good humbucking soundhole pickup without a battery that can me mounted with an end pin jack or temporarily using its attached cable exiting it out the soundhole. These are good for noisier venues like a Seymour Solo UST but are not as natural sounding. Again, EQ will help.
A complaint by some regarding USTs is that the transducer interferes with the acoustic sound transfer between the saddle and bridge. A complaint by some is that soundhole pickups can mare the soundhole or dampen the soundboard a bit.
Then this is where the dual source units come in. With the mic they are more airy and natural but more feedback prone. With the mic turned down and/or their limited onboard active EQ the feedback is managed but the natural sound is lessened.
There are many others out there but nothing is perfect and everything is a compromise. It WILL drive you nutty and reak havoc on your wallet the more you try to chase it. But ain’t that part of what this hobby is all about? ;-)
