I had the K&K "Pure Western' on a Dunn Belleville for awhile, and it was a nice sounding pickup. It had its share of onboard noise, and boominess, but it was pretty resistant to feedback. Truthfully, I like the Bigtone in my Shelly Park Encore much better than anything I've tried so far. She has some "magic" way of installing them, so they sound more natural, and even. A friend of mine recently put a Schatten in his Hodson, and it really sounds good! I'm definitely interested in the Schatten, but not in my Park. (if it ain't broke, don't fix it) Maybe my DA "Manouche".
BTW, it's been my experience with ALL inside the guitar mics, they just feedback too easily. My friend has an Eimers Stochelo Model, and he never uses it (the mic) for that reason. I had the one in my Dunn "Rhythm Futur" removed, and a Bigtone installed. Quack City, but at least I can be heard in a noisy club or restaurant, now.
