Frequently Asked Questions

What guitar string gauge should I use?
Beginners and players who do lots of bending prefer lighter gauges (9-42). Rhythm players and lower tunings benefit from heavier gauges.
Does scale length affect string tension?
Yes, longer scale lengths produce higher tension for the same gauge. A 25.5 inch Fender has more tension than a 24.75 inch Gibson.
Should I use heavier strings for drop tuning?
Yes, heavier strings help maintain tension and prevent buzzing when tuning down.
