Can the offset tubes on this capo be removed, and if so how easily? I play a 12-string guitar with 6 strings on it and I have no need for the offset tubes, but the extra width is necessary.

Furthermore, if the tubes can't be removed, will the Paige 6-string capo fit well on a Sigma (Martin) 12-string (string spacing at saddle is about 2 1/4")?
Disregard this, I went with the cheaper and more universal-looking Shubb 12-string capo.
