Simple enough to use but a bit difficult to get just the right amount of string resonance with the foam shims. Itās almost a little TOO dead sounding on my OM, so I may add another shim and try it on my dreadnought since it has a taller bridge.
I also thought it would be made of rubber rather than foam & plastic, so it being slightly more fragile was a little unexpected. I canāt fault anyone for my expectations, though! It does create a very interesting sound and isnāt a huge investment by any means, so I am overall happy with the purchase.
