Resophonic Capos Sterner TM
 

There are three main principles for capoing resophonic instruments. The first and obvious method is to slip something under the strings, lifting them up slightly.

This type of capo is always  made by hand because it has to fit the individual instrument. They are usually L shaped metal, just tall enough to set at a slight angle under the strings, than twisting to level it and lift the strings slightly.
    The great advantage of this method is that nothing obstructs the left hand! You can easily mute the open strings with the fingers behind the capo. A slight disadvantage is that when the left hand is far from the capo, there is no dampening of the open strings behind the capo.

The Church Key

"Churchkeys"Josh Graves capouser.

Josh Graves told that in his early career he used a beer can opener as a capo:
"It had just the right hight to fit under the strings."

In the US canned beer first appeared in 1935 with flat top tin cans that required an opener. These openers were provided with the beer, and would have a beer compay logo on them. They were commonly referred to as "church keys". In 1962 the first "pop top" beer cans were introduced making the "church key" obsolete.

R Q Jones

Bottom side.

Rudy Jones, Oklahoma made a few of these capos in the late 1970's. It consists of a block of walnut with a groove on the bottom side to fit over the fret, with a stainless steel rod (from a bakers shelf) bent and inserted through a hole with a vinyl cap to keep it from falling out.
     To operate, rotate the rod counter clockwise into the deep groove away from the centerline of the wood, slip the wood under the strings with the groove over the fret, then rotate the steel rod clockwise under the strings into the groove in the top of the wood. It works pretty well on the first 2 or 3 frets.

Bar under the strings
This is my own home made capo made out of a brass rod, rounded in one end. It's flat underneath with a groove for the fret. The groove stops at a small distance from the bass end of the bar. It works on the first three frets. I have another, slightly thicker capo for capoing higher up the neck.

Mike Auldridge uses a similar capo. Instead of using two capos, he slips a brass plate under the capo when capoing higher. The plate has a grove to fit on the fret and a ridge on the top side to emulate a fret.

The next method is to press the strings down on the capo bar.
Warning: Don't use capos of this type on resophonic guitars with a hollow neck!

Whilbro
This capo was made in 1977 or 78 by Bent Whilbro in Denmark. The capo has a high brass fret that is put right on top of the instrument frets. The hight of the fret equals the string hight. Two pieces of aluminum of the same hight as the fret are fastened with screws on each side. They are placed a little off center to make a groove at the bottom for the instrument frets and make the top of the fret stand out by it self. The fretboard is protected by thin, green felt and there is a thin rubber pad for the strings. By fastening the brass fret to the front side of the capo, the strings are pressed down right behind the fret - as a capo should. Clever!

Regular elastic capos Jim Dunlop
A bar to slip under the strings is added to a regular elastic capo. The bar acts as an elevated fret and the capo presses the strings down and mutes the strings behind the bar. It was patented as a "Guitar Converter" to facilitate slide playing on a regular guitar.
US patent 1976 by Jim Dunlop.
Marketed by Jim Dunlop.

[Owner: Philippe Saint-Pierre, France.]

Von Andreae

When the elastic was worn out, this Dunlop capo was modified by attaching a piece of plastic to it with dental floss. The plastic fits over the fret and its springy curvature presses the steel bar up against the strings. The elastic band is obsolete. The little plastic cap keeps the roller pad in its place.

[Owner: Bengt Von Andreae, Sweden.]

 

  Golden Gate

Inspired of the capo above, this capo was designed for resophonic guitars. A Delrin spacer is fastened to the bar. Three spacers are provided to accommodate different string action heights.
US patent 1994 by Ted B Ellis.

  Kyser

On this one the strap is replaced with a hinged bar which is turned in under the instrument neck. The thin, silicone coated bar is placed under the strings and the thick brass bar on top of the strings. Note that the thick bar is fastened eccentrically to the frame. Thus it can be rotated to set the tension and it is fastened with the allen wrench.

Other Shubb capos Shubb
Shubb added a bar to slip under the strings to his original capo construction. The strings must be 3/8" off the fretboard. This capo is approved to be the official Dobro® capo.

The third method is to clamp a weight to the strings. For practical reasons the weight is always
above the strings.

Huckabee Huckabee
In the early 1980's this was one of the first commercially produced dobro capos, designed by Dan Huckabee. A thin, round bar with plastic tubing, pulls the strings up towards the heavy, square bar by means of a screw and a wing nut. Along the bottom side of the square bar there is a routed grove to give it two distinct edges against the strings and the strings are pulled into that grove. The round bar is incerted between the 3rd and 4th strings.

 

Liberty Liberty

A developement of the capo above is to replace the wing nut with an eccentric lever.
Made by Liberty in the early 1980's.
[Owner: John David]

This capo is now (2006) resurrected under another brand and
marketed by Janet Davis Music.

 

Beard Beard, cross section. Beard
This is a refined variation of the capo above. The sqare brass bar is wider and lower. Instead of a routed grove, this capo has a bone edge and a leather pad to mute the strings behind the capo.
Designed by Paul E Beard in 1985.

 

Warren

Warren from above.Warren from the side.Warren from the short side.
From the mid-1980's, beautifully hand made by Jim Warren, of Owensboro, KY. You turn it 90 degrees and slip the rod between the strings and then rotate it back perpendicular to the strings. Then you turn the
lever to an eccentric cam built into the body 180 degrees (either way), which lifts the bar, cinching up the strings against stainless rods attached underneath. The string tension holds the cam in a little detent, which keeps it from coming loose. This manouver was difficult to do with a bar in one hand and fingerpicks on the other. [Owner: Tim Mullins, California USA.]

 

Bradley

Elmer Bradley makes this steel capo. Very similar to the capo above.

 

 Old Leno Leno

The rubber sleeved bar is slipped under the strings and the capo is closed by the hinged lever. When closed the thiner point of the lever points down along the bass side of the neck.
Leno Production ceased in mid 1990's, but has started again. Here is a new one.

US patent in 1987 by Emmet L Hathcock.
Marketed by Leno Capo & Guitrar Company.
Leno also makes regular capos.    Leno guitar and banjo capos.

Sheerhorn Fluxcapo Sheerhorn Fluxcapo
Here the square bar is thin and slips under the strings. The upper side of the square bar is slightly concave to fit the round padded bar and make a distinct edge.
It works perhaps better upside-down. You can clamp it with one finger hooking over the end, and putting the rubber padding underneath keeps the capo from knocking on the fretboard when you hammer-on.
Designed by Jerry "Flux" Douglas.

 

Koyama

Koyama     

The same idea as the Fluxcapo, but the parts are reversed. This makes the bar slim and the heavy weight is placed out of the way under the strings.
Made by Tetsuo Koyama, Japan. [Owner: Shinji Kojima, Japan.]

 

Wilson Wilson
Similar to the Leno capo, but here the clamping force is adjustable by means of a screw. Custom-made by Merv Wilson in Ottawa, Canada.

Holoubek Holoubek
Another one similar to the Leno capo. Here the bar is turned sideways to open.
Made by Stepan Holoubek, Czech Republic.

 

Pothoven

Here is a clever capo. Quickly operated with one hand. It will allways set itself  perpendicular to the strings. The capo is fastened to the strings by lowering the lever. Due to the precision required this capo has to custom made for the string gauges and string spacing you are using. It's not cheap either, but for you who wants that little extra you can order it from:
