  • Hammond L-133 lower manual foldback mod issue

    Hey all, been a while!

    My L-133 has been modified for lower manual foldback and it sounds fantastic when it's fully working. However, lately the second G key on the lower manual is not folding back the low G note on the 8' drawbar, and when I'm on the 4' drawbar, that G is not working on the lowest G key. I think it might have something to do with the really tiny wires that connect the contacts of the keys to the terminals that the loom attaches to.

    I remember Bob Schlicher saying that 1k resistors work "just ducky" (his words, not mine) for replacing the old wires. My problem is that I haven't done this heavy of a disassembly on my L ever, and I haven't done it on my M in a long time.

    Do any of you guys have some advice for working on a project like this and fixing this issue? It only affects two keys, but they are pretty important keys in the lower register, and since the fundamental has dropped off of both of them, it's a pretty frustrating issue.

    Thanks for your help.

    What can I say? I like the spinets! But I wouldn't say no to a B, C, or A.
