K and K Twin vs. Pure (triple head) pickup

[djsonovox]

I plan to install a Pure from K & K in a Sigma Dreadnought Rosewood 28.

I have had good results with the twin system, but I think the hotter output and fuller coverage of the 3 head are worth it. This time I will hook up a preamp I built from scratch off a design by Don Till (www.till.com) that really works great. It's based on a single FET transistor, a J200, I think. I built it and used it as a test device, but now have decided to install it into a separate box. That way, I can use it as a preamp for several guitars that have simply got pickups in them.

The advantage of this kind of preamp is that it goes into and recovers from overdrive in a musical and elegant fashion; and also that the frequency output does not boost the bass, cutting the treble, which is a must for K & K piezo elements, since they are a balanced spectrum without the annoying excess treble you get from so many undersaddle pickups.

I'll let you know how it turns out; or better, post mp3 examples of the results.

Your link to Don Tillman is incorrect. It should be www.till.com

His FET pre is a pretty decent project. Easy to build and it works very well.

Thanks for the corex. I should add that I used the capacitor option that made for maximum volume...it does a fantastic job!

UPDATE: I just got a full-size Pure Western of K & K/eBay. I believe that the larger size and three heads does make a difference.
Funny thing; on the McGuin 12 string tape I just got, he complains that "no pickup system sounds good to me" on an acoustic. Still, it is so much easier not being tied to a mic!
