I was lucky getting Old Git's Shuker for what I think was an absolute bargain (£925), for me it totally eclipses every other bass I've ever played. I was always sceptical about custom basses and wary of other people's opinions of them but having owned and played one pretty much exclusively for the last two years, I get it now.
For the first few years of my bass playing career, I hopped from one bass to another trying to fine the mythical 'one' and got nowhere. I was obsessed with the instrument and not my playing and would spend the whole gig listening to my tone, fiddling with this knob, tweaking this and that and not taking a blind bit of notice of what was going on around me.
I now have an instrument that, because I'm completely happy with it in every respect, let's me forget all those physical aspects and allows me to concentrate 100% on my playing.
Great if you can find something cheaper / mass produced that takes you to this happy place, I'm not a bass snob but if I were ever in the market for something else, I'd be heading straight to The Peak District or Moffat.
