Very nicely designed & 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 may achieve exactly the tension you desire 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 & Rob Ickes, among others. Also an excellent choice for lap steels. Walworth Reso-Guitar Capo
