Guitar: feedback busters?

what does anyone think about using them. rubber discs that go in the soundhole of guitars?

Never needed to use one, but...

I've a Jazz / Rockabilly hollow body archtop with 3 P90 pickups
that howls like a banshee anywhere near a guitar amp.
Theres's a guy in USA who sells made to measure F hole bungs to suppress feedback.
Which look like they are cut out and made from the soles of flip flops...

I used to use a Boss acoustic foot pedal with built in feedback suppressor - a notch filter of some sort..
But it was too much faff trying to use it on stage with a piezo pickup mandolin...

I have a Seymour Duncan soundboard pickup in my old Lowden and if I want to jack up the volume I have to use a flapper, otherwise it starts to feedback as the volume goes up. It doesn't seem to effect the sound too much. A preamp with a notch filter helps but it also compromises the sound quality, IMO.

I use Planet Waves' 'Screeching Halt'. Yes, it helps, but I'd have have bought it anyway with a name like that.

it seems to me to lose resonance.

i recently sarted using the fender gt100 amp. and to be honest , you need to lean on the power of PA system. i've been using the feedback busters to create more headroom - to me the guitar tone is not so beautiful.

i wonder if i'm alone feeling this.

Having sat in the audience and listened to my guitar (with a flapper) being played through a PA I think I know what you mean. It did seem to lose some resonance but the fundamental comes forward a bit which, to me, is not a bad thing. You couldn't detect all those overtones that you get playing unplugged but the sound was very discrete and penetrating while still retaining some acoustic ambience. Of course the guy playing it had a marvelous touch.

...oh and re notch filters, I have a couple of them on my acoustic amp (which I use mostly as a monitor) and they do help control the bothersome frequencies but with a flapper I don't need to use them as much. I think I get better sound that way.

I used to use one when I had a Rainsong. It would howl like a banshee with some wedge monitors... It worked and didn't seem to affect the sound from the LR Baggs element.

My only gripe was the guitar top is very thin around the soundhole on carbon fibre guitars so it was loose and I needed bluetack to stop it falling forward and catching my fingers when picking.
