Lately I've found myself playing only pieces that require extensions (or 5er's) and move from below the E to octaves higher and i've had enough of those big shifts. Especially after my bass skooted forward and got scratched by my bows tension screw(damn Appalachian Spring). So I just installed the capos from basscapos.com and man are they a sinch to install. All you do is follow the instructions from the website. And since i have an all ebony ext., as it states on website, i used a slightly bigger bit to drill hole. I do wanna advise people to be sure to have a friend with them when doing this and if u don't keep a grinder with you(for Eb) then lowes/home depot sales attachments that u can connect to a drill. Also ebony will get real hot, as well as the drill bits so be carefull. Also the sound they produce is amazing. its like theres just a whole other string on my bass. In comparison to all the other famous stops and extensions (yes bass world, I have encountered all the different types of extensions from the most famous U.S. and Canada makers and tried them) I would recommend this set-up as far as cost-efficiency (as i got fingered ext first, and bought capos years later), ease of install and to use, and quality of material. I'd like to taste the beef on the cow the leather came from, its just so nice. Well time for me to go get ready for Mahler 5 rehearsal.
