I have spent too much on kit. I have had 90% of the lush preamps out there - I know which one I prefered. I have owned what I consider the best backline out there - there is a pleasure in amplification which reaches all the way down there without giving up. I have had a solid 80% of bass guitar options. An instrument which responds equally across the range will always make me smile. I like a 33" scale because the strings are a bit more rubbery.
As soon as Drums Rex and The Guitarmageddon kick in, any subtletly just dissapears.
And after too much time in loud environments I cannot play without earplugs so even if any of the subtlety is there, I miss it.
Does this stop me owning more basses than I need? Nope. But it is cos I like them, not because anyone else, including me, will hear any difference when the chips are down.
