Here are the basics from Phil.
"I have never been able to use a Realist in high volume situations. The Full Circle has a far more usable sound in high volume contexts.
The more resonant and loud your instrument is the harder it will be to amplify. The best orchestral basses just don't respond well to playing amplified loud. Good sounding but quieter tighter basses will amplify loud easier. Poorly set up basses won't amplify loud well either. Any deficiencies in setup will be magnified under amplification.
I have played ridiculously loud in small and large venues with huge rock bands using my plywood New Standard Cleveland bass with a Full Circle pickup into an AI Focus 2RIII and Euphonic Audio VL208. It manages to still sound like a string bass too."
1. The onstage bass volume should be low, feel the low end and presence of the bass through the PA.
2.Use the onstage system with mids and highs only as a personal monitor to stay in tune.
3.Dial in the front of house sound without any on stage sound whatsoever and then turn up your rig just enough to play in tune when everything else kicks in.
4.Try to get whatever personal monitors you use up off the floor near your ear and away from the body of the bass.
Stay well behind the main speakers and well away from the subs.
5.Keep the bass out of the floor wedges and stay as far away from any on stage speakers as you can.
6. Use the rubber stopper on the endpin and don't stick the pin directly into the floor.
7.Experiment with phase reversal on the preamp.
8.Experiment with high pass filters on the preamp. (try the fdeck preamp!)
9.Stay away from compressors in your rig or on your channel in the mains.
10.Place a foam wedge or towel between the body of the bass and the tailpiece if you still have feedback.
11. Weave a strip of velcro through the afterlength of the strings between the bridge and tail piece.
12. If there is no PA and you are trying to get your rig as loud as you can put it in front of you pointing out at the crowd. You'll hear it just fine and it won't feed back near as much as if it's behind you or beside you.
