How we ranked these capos
Every pick ranks in Amazon's best-seller list for its category and has a listing with real specifications. The order mixes two things: how each model compares on the specs below (higher share of the best value in this group scores more), and how widely it is bought. The spec score runs from 9.0 to 9.8 and only compares these picks with each other. A spec the listing does not state is left out and the other specs are re-weighted; a listing with fewer than 2 stated specs is scored at half. We do not test gear in person. Full method.

Buying advice: capo for martin
Match the capo to your neck width
A capo must press all six strings evenly without pulling the guitar out of tune. The Ortarco pack fits necks from 38 to 45mm, which covers most 6-string necks, so measure your neck before you buy. The Martin starter pack capo adjusts to almost any guitar neck profile, which helps if you switch between guitars with different neck shapes.
Decide whether you need setup tools too
A plain capo only changes the pitch, while the MusicNomad kit measures and adjusts neck relief with a gauge, a pick capo and a 5mm wrench. If you only play, a capo pack is enough. If you set up your own Martin, the gauge gives you the three common relief measurements of .006, .008 and .010 inches, and the wrench fits the truss rod.
Check what comes in the box
Each of these is a kit or a pack, so compare the extras. The Ortarco pack holds two capos and five picks in a wooden capo case. The Martin starter pack holds a capo, a clip-on tuner, a pickholder strap and six picks, with a 1-year warranty. The MusicNomad kit holds a gauge, a pick capo and a 5mm wrench, with a 2-year warranty.
