Okay so we're getting very nerdy and practical here, but this is the kind of gadget that most guitarists would never think to buy for themselves. However, they will thank you for it...
Stretching new strings is a vital part of the equation when it comes to keeping guitars in tune. Over to Total Guitar, who recently gave the String Stretcha a very healthy four stars, to explain how it works:
"It hooks around the string and then you slide it up the length of the scale. String Stretcha recommends two passes at each string (more will apparently overstretch it). We’ve tried it and only had to make a couple of minor retuning adjustments once we’d stretched the strings. After that, they were settled for good. Result."
