Re: 10 Best Ways To Fight The Evil Of Feed Back,input Please
In all seriousness....it depends;
...from a sound engineer point of view (which I was for a long time)....and in no particular order....
#1. Stage monitors - use good 32 band +/- 18 db EQs, and dynamics mic that offer the best gain before feed while getting the sounds you want (SM58s work well, but I like super cardoid patterns better on tight stages)
#2. Gates for drum mics (toms and kicks), keeps low end rumble and feed to a minimum
#3. Guitars - get some good pickups, reduces microphonics, use good tubes for less amp noise
#4. Bass - get a good DI with ground lift, if you get too much buzz, mic the bass cab - its still better than a ton of buzz (not so much a feedback thing)
#5. Careful with the mid/high cabs for the front of house, its not uncommon to have spill back into the vocal mics in small rooms
#6. Good front of house EQs, much like the monitor rig, each room will react differently and at different frequencies.
#7. Keep the stage volume down, you only need to be loud enough to keep up with the drums, not play Woodstock with just your amp - this should be number one!
#8. Tell your deaf singer that his vocal monitor does not need to be as loud as the front of house!
#9. Have enough front of house power to mix what needs to mixed and mixed properly, a crap PA will always sound like crap, and even worse when pushed beyond its capabilities - cranking hot mids through an underpowered PA is asking for feedback hell.
#9. Good gear and tone mixes better than crap tone, know your tone and how it fits in the band context so you won't be cranking your amp to 11 to hear yourself because use three EQs in the loop to suck all but 50Hz and 10,000Hz out of the sound!
10#. The golden rule of sound - "**** in, **** out!" If you, collectively as a band, suck....well, the engineer will be the first to know it, feedback is usually a sign of having a hard time getting a good mix for any number of reasons
