How To Install New Tuners
Upgraded machineheads can improve ropey tuning, here’s how to properly fit them like a pro
As with most guitar parts, the tuners that come on your guitar are often not much to shout about. nice shiny set of machineheads can help out with your guitar’s tuning stability and offer a smooth tuning experience. However, the tuners themselves are not entirely to blame for the guitar’s tuning stability.
In brief, the tuning stability checkpoints are: string wrapping technique, tremolo or bridge, string ball ends, the tuners themselves and friction points. The friction points are string retainers, the nut and the bridge saddle tops. Now we think of it, this deserves a dedicated article on it…
So our point was that the tuning machines/tuners/ machineheads (call them what you will) are only part of the equation. Now cheap tuners don’t help one bit as the quality of the gearing lets them down. This lowly Squier Affinity was a very deserving candidate for some fancyschmancy Gotoh locking tuners. Stay tuned and we’ll try and keep it staying in tune.
1 Let’ s whip off the old ones. This lovely 10 mm ratchet spanner is just the trick. Your tuners maybe different but these ones have a nut on the front only. Watch out in case you have the fiddly mini screw son the back, and spend a bit of time researching the shape/ fixing soft he tuners you need.

3 A simple thing but it’ s often done wrong; this is the order you’ re going for with the fixings: nut, washer, head stock then the tuner itself on the back. These Got ohs had a nice looking side to the washer and a dull side–place it nice side out of course to show off your wares.
4 Bung them on. For now we’ re just doing up the 10 mm nuts( and washers) finger-tight and not worrying about them being crooked. These Got oh tuners are also ‘staggered height ’– some are tall er than others to compensate for the angled headstock. The tall er ones go nearest the nut and the shortest near the head stock tip.
5 Jack’ s Super Hack: use a set square to get the alignment bang on! It looks really crappy when tuners are installed wonky so make sure you’ re not one of those bod gers. Use the main body of the set square against the head stock top. On a St rat type guitar of course they want to be 90°.
6 Having lined up the tuners perfectly, fetch your jabbing implement and get jabbing. Be careful not to disturb the tuners whilst you’re a-jabbing. This will be the location of our screw holes. If you don’ t have a jabber( the real name for it is an awl) you can use a longer screw or knitting need lee tc.
7 Now you have marked the location of all the screw holes, let’ s drill them. The big no-no is drilling all the way through – stick masking tape on the drill bit to mark the depth. Maple is very dense timber so a 1.5 mm drill bit for a 2 mm screw is a good pairing. If you drill too small a hole the screw will likely shear off.
8 Steady your hand and drill into the head stock. Remember that maple is a dense wood and very unforgiving. So be careful not to drill too deep and be extra careful not to snap off the drill bit in the maple. You don’ t want to have to excavate a broken drill bit.
9 Replace the tuner sand finger-tighten the 10 mm nuts on the front again. Use a candle to lubricate the thread soft he teen y-tiny screws. This will ease them in and ’cos it’s not oil it won’t stain the maple. If you don’t have a candle handy, a bar of soap will do.
10 Screw them in using a PH 1 screw driver. Blow off the excess wax as it crumbles away. We recommend a hand screw driver as you can feel the torque and, more importantly, you can feel when to stop. As these screws are so small and fiddly they don’ t need much persuasion before they break or strip. Go easy on them!
11 Nip up the 10 mm nuts on the front with your spanner, being careful not to slip and scratch the head stock face or your lovely chrome-coated nuts. These are responsible for the machine head’ s stability but, again, don’ t over do it. These 10 mm fell as can be quite delicate despite them looking pretty hench.
12 Give the alignment on the back one final check and then string her up! These locking tuners don’t need any string winds, so pull the strings tight, do up the thumb wheel lock son the back and then tune. We always recommend stretching your strings in even with posh tuners. That should do it!
