This is my 1966 Gibson Kalamazoo that my dad bought from a friend in college in 19 . He never played it much and for the longest time it sat in the attic gathering dust. I found it cleaned it up, put new strings on it and it played like new for awhile. But recently I've noticed the sound quality going down and traced the problem to the pickup. I researched it and found that the KG-1, has 1 single coil "melody maker" pickup. I love the sound of this guitar and would love to replace it with another melody maker, though if there is a newer pickup that has the same tone quality as the original I'd like your opinions on if I should have a new pickup installed or an older one. I really love this guitar it was my first and I'd hate to not be able to play it anymore. Help! - Mike
