Nothing really gets me wound-up but my own thoughts on Jason Karloff's list are:
1: Fender's Sunburst. I have no problem with this at all.
2. Fender Multi Stringed Instruments. I'm a convert to the "Stick with the four string thing", (From a personal perspective, I'm not so sure about the "You are good at it" bit though !). I went back to 4 string Basses about 4 years ago, I tried my 5 string Bass at a recent rehearsal and decided fairly quickly that I preferred the sound and feel of a 4-string Bass.
3. People calling pick ups "pups". Agree 100% with the OP, they're 'Pick-Ups'
4. 99% of all top end basses for sale in Mainland Europe. Agree 100% with the OP, especially in terms of visual aesthetics. I find most of the 'Boutique' basses extremely ugly - in particular Single Cut basses. Some of the woods and finishes are stunning but, the geometries of some designer guitar bodies are just wrong. I have no problem with painted bodies.
5. Wood Pickups. Agree 100% with the OP, they don't do anything for me.
6. Fret Dots. I'd be lost without them ! !
My deal breaker would be ................. Coloured Headstock - just looks wrong to me.
