Shadow SH NFX EP-A

I like this pickup. It has a dual layer which senses some of the vibration of the top of the guitar. This is fitted to a cheap Gibson DSM and this has become my regular stage guitar, mainly due to the addition of this pick up. It is very clear and I can play on some very large stages with it. It does suffer from some rather bassy feedback, but this is mainly the fault of sound engineers not paying attention. I do have an older EMG undersaddle fitted to a much more expensive Lowden Acoustic, but this pick is much much better because the the EMG is brittle and this is smooth.
This coupled with the Nano Mag would be a brilliant set up.

Top quality product with a beautiful rich sound. Reasonably easy to fit yourself - though it took a little fettling/fiddling when it came to drilling the hole (not easy to put a power tool right into a treasured possession like that!) though I think I didn't have the correct size drill bit - so my own fault - and getting the cable through - probably a half hour job to do it right.

Only negative for me is the little case that holds the battery is supposed to stick to the inside of the guitar - but the adhesive pad on the bottom of it has picked up dust and debris inside the guitar and over time has lost it's tackiness and now tumbles around inside - which is not good - so Shadow should look at an alternative way to secure the case - which which would still be easy to remove and change battery etc.
