Manson C-string tuner for bass

The hidden problem with low-C extensions

If your bass has a C-extension, you'll know the frustration: turning the peg does almost nothing for the first few rotations, then the pitch suddenly leaps. Trying to land precisely on a low C by ear, through that kind of mechanical imprecision is very tricky - and it's a problem exacerbated by extensions with their extra length and the routing of the string around or through the scroll.

The fix: a dedicated C-string tuner

The Manson C-string tuner sits between the bridge and tailpiece, giving you fine, immediate control exactly where you need it - without replacing your C-string or modifying your setup.

This matters more than it might sound. Fitting a traditional fine tuner means taking the string off, threading it onto the tuner, and re-attaching it at the tailpiece - and because the tuner itself takes up a couple of inches, the string's length behind the bridge is now shorter by that amount. That shortening drags the worn, gnarled patch of string that's been sitting on the bridge notch for years up into the bowing zone, where a bow drawn across it will quickly chew up your bow hair. The only real fix is a new C-string - and a re-hair for your bow, if it's gone that far. Because the Manson tuner clamps onto the string you already have, between bridge and tailpiece, none of this happens: it can be fitted or removed at any time without the string moving at all.

It's machined from a single block of anodised aluminium: lighter than the steel tuners you might be used to, with every edge smoothed so it sits comfortably under the string and in the hand.

Fitting takes seconds

Detune the C-string by roughly a quarter-tone, slip the tuner's two feet under the string so it sits in the channels, then tighten the screw until the tuner grips the string. That's it - ready to use.
