K&K Banjo Twin

Nice midrangey sound, cuts through the mix but don't expect it to sound exactly like you hear your banjo naturally. Kind of a retrosound, lows and highs are attenuated. I use it on my Deering Goodtime openback. No feedback issues.
One of the transducers lost contact with the self adhesive tape, but I was able to push it back on and it has stayed there since.
The outputjack won't stay put with just the supplied velcro, I had to go trough several combinations of plasticstrips to make stay on the clamps. You can of course drill a hole in the banjoside and fit it like an endpinjack on an acoustic.
