I have had an Orange O-Bass for about a year kept stock with the exception of replacing the strings with La Bella stainless steel roundwounds. I love the Bass, it has been my go to for uncompromising, nasty and overdriven sounds. Recently I took a tumble at a rehearsal and snapped the D key clean off, no damage to the Bass but the tuning key will have to be replaced. I have decided that this was a perfect excuse to do a full upgrade. My current thoughts are to replace all the tuners with Hipshot HB-1 tuners, the bridge with the Hipshot Kick Ass Bass Bridge and the pickups with the DiMarzzio DP127. I am looking for thoughts and opinions on my choice of upgrade and any experience anyone else has with upgrading one of these Basses.
