Well, I've tried and tried not come to this decision, but I'm beginning to think there is no other option. I can't play it standing for any period of time and I can't play it seated either. It's not actually that heavy (maybe 11lbs,I'm not really sure), but the way my back is it's too heavy for me now; it's just not really worth it anymore. Sometimes beauty comes at too high a cost.
So, I'm inviting interest in my Triple O, based on a MK Sig Standard but with extras including superb (and I mean superb - the nicest piece I've ever seen!) walnut top and back facings, knobby headstock, dummy humcanceller, purpleheart kneck lams, and both collet and hat knobs (just take your pick depending on your mood!). The bass is mint, sadly has never been gigged or even rehearsed, and has been in a smoke free house since it arrived. See Factory to Customer thread Shaun's Triple O and showcase thread Bigbadbill's Triple O Sorne-Rama for pics and details.
As it's mint, and assuming I do decide to sell, I'm looking for ?3000UK.
