Precisely machined and carefully hand assembled, a Shubb capo is manufactured without compromise. Its ingenious design enables a patented locking action which provides an unrivalled combination of power, speed, accuracy and ease of use. Shubb’s model 3 capos — “for 12-String Guitar” — are 2.25″ wide and curved. Not strictly for 12-strings, they fit any steel string guitars with wide fretboards.
