In 2012, my Schatten HFN Artist experience indicated that you've got to make sure all three feet of the pickup base make and stay in contact with the brideplate. This means possibly having to sand one or more of the feet to comply with the curvature of the brideplate when under string tension. I used the thin foam supplied with my Scahtten HFN Artist (ordered directly from Schatten Design) to mount the pickup in two different guitars but the amplified tone was too thin and I suspect one of the legs made less than ideal contact with the bridgeplate. I ended up sending the pickup system back to Schatten for a refund. There's likely no reason this system shouldn't supply excellent amplified tone when installed with a proper and lasting mounting. One of the things I liked about the pickup was its rosewood three-legged mounting with the piezo system running along the top--it looked so cool!
