Very nicely designed and manufactured squareneck resonator guitar capo. Made of heavy brass, this capo utilizes an easy cam action flip lever to tighten the capo to the strings. It also has a tension adjusting set screw so that you can achieve exactly the tension you need to maintain clear, ringing notes. Includes an Allen wrench for the adjusting screw. Measuring 2 1/2" long, this capo will fit most 6 and 8 string guitars. Made here in our home state of Michigan and heartily endorsed by Tim Graves and Rob Ickes, among others. Also an excellent choice for lap steels.
