Capo on Acoustic vs Electric: Fit, Radius and Which Capo Works

Verdict at a glance: Do not assume one capo fits both: acoustic necks are wider with flatter radius, electric necks narrower and more curved. A capo listed for your guitar type, seated just behind the fret, beats a strong wrong one. Adjustable tension travels between guitars best.

FAQ

Can I use my acoustic capo on my electric?

Only if it seats evenly across your electric's radius without pulling sharp - test at the 2nd fret and re-tune; if it buzzes or bends, buy the right fit.
