OK got the bass, so far it sounds a lot better than my old slotted headstock bass. The owner had the serial number, it checks out to being made sometime in Kalamazoo in 1965. Now a question: Is there any way to increase the bottom in pos 3? It seems like there is a low cut going on somewhere in there. Years ago I either bypassed the choke or just unhooked it, can't remember which but I got rid of the bass shortly after and can't remember what effect if any it had on pos 3. On pos 3 it sounds good from the E which is an octave up from low E but seems to lose bottom below that E, is there anything I can do short of major surgery to fix that that anyone knows of?
I just found the old thread sound difference between 60's and 70's EB-3 basses and re-read it. I remember the EB-0 mod which is what i think I did 8 years ago (because I said I did!) and actually don't think this bass needs it because I have been getting a good sound in pos 3 playing with the bridge volume control to where it does have some good bottom. This bass sounds really good, much better than my slot head ever did. Maybe 30 year old strings have something to do with it? I ordered some Labella flat wounds for it. We'll see how those sound and play, I ordered the fat ones, .049 to .109.
Now I'm wondering what to do with the finish I am starting to like it the way it is but I don't think that big black dirt mark is ever going to come out so I might go down to the Guitar Factory and see what they can do after all. I don't want to change the sound of this bass though.
BTW I took the neck humbucker off and also the pick guard, whoever stripped this did a good job, I can't see any trace of the original clear or any other color, I think that this is the original color, whatever it is.
