MIA knurled telecaster or P bass knobs
These knobs are required by all who want to install an Obsidian Wire harness onto a MIJ P bass. Japanese worked with radio pots they could find on their market as they were produced there. As s consequence, the shaft of these pots have a different diameter when compared to the corresponding American ones; moreover they are generally splined whereas the MIA ones are smooth, only relying on the side screw to let the knob stay in position. These guys are not the only thing you need to install the harness on MIJ P basses ... the Japanese pickguard hokes gave Aldo been sized for thdxsnakler diameter of the true ant pots shaft ... hence the holes dia. shall be increased using a drill or an original MIA pickguard shall be installed. I went the second option and I purchased the knobs from here. They were delivered to Itg in less than 10 days. Satisfied.
