Does anyone know what kind of tool is required to adjust a Hofner HCT 500/1 truss rod?
A picture of the adjustment nut would help.
It's just a metric allen wrench/hex key. I can't remember the exact size.
A key. I was thinking of the nuts like on the German Hofners. No wonder I couldn't get a socket to fit. I'll get my set of metric keys and poke around.
I'll let you know when I get it right.
That's a deep location. I couldn't get my standard metric Allen keys to reach down there. So, I used my longer English measurement ones. I poked around with a 5/32 inch size, and it fit almost perfectly because it's 3.968 mm - or almost 4mm exactly. And that did the trick. I now have some relief on my Hofner's neck.
Thanks for your guidance.
4 mm rings a bell. Yeah, it's pretty recessed. Luckily, my CT has been remarkably stable (I rarely even need to tune it!), so I haven't had to poke around in there very much.
Very true about the stability of the HCT 500/1. It's just that mine had no relief in the neck when I bought it, and I wanted to add some. Thank you for pointing me in the right direction.
Do yourself a favor, and get a 4mm hex key - maybe a T-handled one - that will reach the nut. Yeah, 5/32" is almost 4mm, but that "almost" has ruined an awful lot of 4mm truss rod nuts...
Agreed, a 4mm hex key only costs about 50 cents around here.
I know the Icon/Ignition uses a 4mm. I would imagine the CT doesn't stray too far from that, if at all.
