Speaking of adding a neck MFD to a Climax/L1500/Kiloton - this is my 'Climax2K' project. Passive - parallel/sc/series switches for each pickup and vol/vol/tone. I like it a lot, probably better than the L2Ks I've had to be honest. I am just not a bridge pickup guy so this gives me more tones that I like. Granted both pickups are pretty much always in series and I'm mostly 100% neck pickup only, but the sweetspot pickup alone sounds good to me and blended give some nice tones. My L1K is still my main G&L but this lets me have the L1K tones I love (I take the OMG cap out of my L1Ks and use 'plain' series most of the time) but with a little something spicier on tap for when I want to change it up.
The first two numbers of the S/N will give you the year of manufacture.
