Re: microphone feedback cures
Yes, give us some more information about playing style, volume, stage volume, microphone, mic position, monitors on stage, other instruments on stage ...
I perform and do live sound , acts are bluegrass, folk, singer/songwriter, acoustic jazz ... I always work on my live rig for the best possible acoustic sound on acoustic guitar, mandolin, banjo, dobro, bouzouki. Although I made sound for classy bluegrass acts micing each instrument separately or using only one mic on stand for the whole band with great results I never could find a way to use only one mic in front of my instruments, always lacking cutting through power on guitar. Although I play pretty loud on a powerful dread, use a decent microphone and personal monitor. Settings are acoustic trio up to six-person line up including drums, stage volume is moderate, venues are 100 to 500 people clubs and open air. So I opted to use an additional pickup on guitar whereas mandolin and banjo play into the mic on a boom stand. I first dial in the right level for mandolin and then add a bit the pickup from the guitar.
Some advice to eliminate feedback when using a mic in front of an acoustic guitar:
- Start with the mic pointing at the 14th fret as close as possible for optimum gain before feedback
- a mic with flat frequency helps reduce high end feedback (or bring down the treble a bit without sacrificing airiness from the mic)
- some significant low frequency roll off up to 200 Hz helps reduce low end feedback and boomy, muddy bass content.
- a flat response monitor with some low freq roll off properly placed (off-axis to mic) helps
- try reduce stage volume
- stay behind the main speaker line as far as possible
- avoid bandmates who need to be loud on stage (I know what I'm talking about)
- every venue needs its own treatment / EQ
This is from my experience, maybe there is something helpful for you.
