Klark Teknik DF 1000

When used in small rehearsal room or small live settings with a cranked up Bose L1, it have made a notable difference many times.

Of course it does not make mic positioning fully obsolete, but, it does remarkebly well in reducing unexpected feedback when you for example gig in new places/environments/venues and when you’ve not had a lot of time to soundcheck before.

Absolutely worth it as a backup-plan. Especially if you don’t have a dedicated soundman or someone who can react really fast if things go south. Gives you a little head start to make adjustments in sound settings.

And also, fully automatic. Just turn it on. Sometimes you just notice it when you for some reason turn it off and, ow!, there’s that screech. When in new environment just press the one and only button, reset, and let it find the frequencies.

It make take a couple of seconds before it understands what is going on and reduces the frequency.

I bought another one after this. Just because it’s so nice to not have to worry too much and just concentrate more on your playing. Really recommended. And not that expensive either.
