Tinnitus.
The amount of Basses I got through was frightening now I look back, Had a least 5 custom made Status Graphite's made 4,5 and 6 string. I had a Shuker 6 string headless made, had Dingwalls, Alembic Mark King x 2 one only lasted a week as I couldn't get it set up right. Ricky's, Stingrays, Warwicks, Yamaha, Sei, the list goes on, all in the name of trying to find the perfect bass. Didn't own them all at once you understand !
Used to smuggle them into the house at one point :-)
I also owned the Status S2 Classic "Miss Myrtle" that is beyond doubt one of the nicest Status S2's ever made. Sold it as I couldn't get it setup how I liked it.
Last bass i owned up till recently was a Fender Jazz Deluxe 5 string. Then I ended up with bad tinnitus that I've now had 24/7 for the last 5 years. The Jazz sat unused for 2 years so I sold it.
Not played at all for 3 years, but recently bought an American Jazz Deluxe 4 with an East Pre in it. Now I'm back on here trawling the basses for sale forum again, so God know's what will happen.
