Rickenbacker 4004L Truss Rods. Really?

[Woodinblack]

OK, so I need to do the strings on my 5 string ric, but the nut is too high and the action is too high, so tonight is the night to sort it out. Was really worried about filing the nut down as it always goes wrong, but for whatever reason, today it didn't, I filed the nut down and it is mostly ok (I could have probably gone further but its close enough). So next job the action, might as well adjust the truss rod, take off the TRC and.. oh, two truss rods, I thought that was just a 4003 thing, rather than a ric thing.

Still, how hard can it be, head to youtube to see what needs doing. First video, guy loosens the truss rods, bends the neck back manually, does them up and says thats fine. OK, that can't be right, second video, have to skip half of it as hes just spending his time time talking, drinking and smoking, but then he undoes the truss rods and bends the neck down. hmm.. then I tried the 3rd, same thing.

 

So at this point it is either a global conspiracy by bass manufacturers to break rics or is that is actually how you adjust a ric neck?

This freaked me out so I had to google it.

 

I found this:

It give a detailed explanation (and also hints that more modern rics may work differently). There are hints that you might strip the truss rod threads or cause the fretboard to pop off, and that you will probably end up with more relief than you want because the process is so scary:

Rickenbackers of older vintages use a dual truss rod system but it works entirely different. The tightening of the nuts does not change the bow of the truss rod, but instead ‘sets’ the neck where you physically put it.

 

 

What can I say? Good luck, and video the process, so if it goes wrong at least you can get a viral video on Tiktok.

Well, that is sort of what I thought, but this is a 4004L which is anything but vintage, but sure enough it does have twin truss rods that look just like the ones in the 4003.

Luckily with the bridge drop and nut reduction, it is much lower than it was, so it isn't so much of an issue, other than there is nowhere to go if it was wrong, and I do need to change the strings, so my current dilemma is that I have a pack of 40-125s, and a pack of 45-130s!
