Crafter Sound Sinker Pro Acoustic Guitar Feedback Suppressor
Safe and secure checkout
If you've ever had your acoustic guitar squeal through a PA mid-set, you'll know how quickly it can derail a performance. The Crafter Sound Sinker Pro is a simple, affordable fix that sits in your soundhole and stops feedback before it starts.
It's designed specifically for acoustic guitars with a 100mm (3.93") soundhole diameter, and the whole thing takes seconds to fit. No tools, no modifications, no fuss — it just presses into place securely and gets on with the job.
Does It Actually Work?
Feedback on acoustic guitars is caused by the soundhole picking up amplified sound from the speakers and creating a loop. Blocking that opening — even partially — breaks the loop and dramatically reduces the problem. The Sound Sinker Pro does exactly that, and because it's made from flexible, durable materials, it fits snugly without marking or damaging the guitar.
It's a well-established solution that gigging acoustic players, teachers and session musicians have relied on for years. Small, light, easy to carry in a gig bag pocket, and genuinely effective.
Works With In-Body Preamp Systems
One thing that sets the Sound Sinker Pro apart from a basic soundhole cover is the cutout that provides clear access to in-body preamp systems — including the Crafter DS-2 Pro+ stealth tuner. So you're not fumbling around trying to reach controls through a solid block, and you can still read your tuner clearly mid-performance.
Who Is It For?
This is a useful bit of kit for anyone who plays an acoustic guitar plugged in — whether you're a solo performer playing live gigs, a teacher working in a classroom with amplification, or a session player recording in a live room where feedback is a risk. It's also worth keeping one in your case as a backup even if feedback isn't a regular problem for you. At this price, it's cheap insurance.

Not Sure If This Fits Your Guitar?
