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.

I purchased this item due to the need for a very thin transducer to fit the fairly shallow saddle slot of a 00028. This is one of the few that could be fitted without the saddle becoming unstable.

Simple to install and the included instructions were very good.

The 2 issues i encountered were the weak adhesive on the velcro fastener for the battery bag coming detached from the inside of the guitar so i glued the velcro patch with instant epoxy in the end and the fairly short barrel length of the pre-amp/jack plug unit was only just long enough to pass through the tail block of this guitar and still be able to use the strap ring.

Sound is typical piezo although quite pleasant with a bit of external EQ. Not as 'piezo quacky' as the more common crystal element transducers i have used and acceptable when playing fingerstyle but some 'quack' evident with aggressive flat picking.

Very feedback resistant and battery life is very good, pre-amp is very quiet with no added hiss or hum evident.

Very satisfied with this purchase.

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.
