Tom- These are the best pickups I've heard in the twenty-two years I've owned this guitar and I've tried over a dozen sets. Great for everything from Country to Classic Rock, and a must for Blues and Jazz players." Thanks so much to Mike Ricca for working with me on the developement of this set. People who know Mike know that he has a great ear for tone and a great reputation for his ability to get the most from a vintage amp.  After a few months Mike and I have arrived at the perfect combinations. Neck Approx. 5.9k and Bridge Approx. 6.6K for the Vintage Low Wind set and Neck 6.3K and Bridge 7.2K for the Vintage Hot set. Nickel silver solid covers. Choose Alnico 4 if your guitar is solid and punchy to bring out the wood and brighten it up. Choose Alnico 2 if it's resonant and bright, to tame it and warm it up.These will transform any guitar into a sweeter, more expressive instrument. By the way, Country/ Western Swing players can get that early Epi sound and Waltz Across Texas by putting a set of these in a Jazz guitar! Bravo Mike!
