Re: Kahler tremolo?
I have put Kahlers on a couple of my builds.
This is my estimation of their worth, only mine, I know some people love em.
I used the Kahler Hybrid trem
The spring inside is no good if you want to use what Kahler call heavy strings. I did a bit of research into what they considered heavy guage, and it turns out they say 10's are heavy??? go figure.
They do produce a heavier spring, which helps alleviate a few return to zero problems, but not all.
The bridge is big and HEAVY, This does not really translate into any usable tone bonuses.
They are relatively easy to fit, the rout is only onto the top of the body.
I found a way to set the spring, which works OK for me.
First screw in the little bridge locking screw at the rear of the bridge. The gap that the screw fits into is slightly oversize, so you tune up, and then adjust the spring so that the bridge floats between the top and botton of the screw gap. It is a bit of mucking about, but it works.
General impressions...
The intonation of a Kahler is a PITA. the allen screws that fix the slide are directly under the string, and there is no srew adjustment of the slide, you have to get a small bladed screwdriver and jemmy it back or forward to get intonation, as such it is mediocre in that department.
The saddle heigh adjustment screw is also directly under the string. so there has been a bit of a design glitch in that whole area.
I recently asked my clients with this bridges how they found them, ALL of them now have the tremolo locked down with the screw at the rear. So that might or might not say something.
ALL tremolo's are a flawed design. All of them.
Kahlers, Floyds, wilkinsons etc have tried to address this problem by trying to fix Leo's original design (flawed).
This constitutes the much loved phrase "Polishing a Turd"
They all rely on the balance of the strings in conterpoint with the springs of the trem.
Until someone comes up with a design that allows the strings to be independant of this equation, then ALL tremolo's are a flawed design, based on first principles.
And yes, I have a design in my head, but I need to talk to a switched on metal fabrication dude before it gets out there.
upshot.....
Get a fixed bridge...
no just joking,
The best tremolo I have come across (still flawed, mind) is the NOS PRS trem unit by MannMade Industries.
I believe these guys were the original suppliers to PRS, before PRS got really big.
These are good, the whole tremolo is milled from a single block of steel, not just the string block, thats the top and everything.
But they are not cheap.
So there you go, my PERSONAL views on trems and the Kahler in particular.
