Today I installed an updated cable hub from Dixon. The bolt holes are of a bigger diameter to allow the two larger t-rods to anchor the cable to the cable hub in two places between two lock washers and two hard rubber washers. It is now impossible for the cable to jump off of the hub. The cable can still break, and they do occasionally, from what I've researched BUT, it can not move! I've been using it with the new beater and mount I constructed for about 30 minutes to some Van Morrison tunes. So far, so good! To be honest, we are leaving for Mexico in a couple of days and double bass pedals are going to be the last thing on my mind!!! I need a break before I even experiment on my vintage Tama double bass. Better have a few cold ones just to get my system lubricated for muchos cervezas!
