Thanks!
Yeah, I realised as soon as I delved further into it that it might not be such an easy fix with a new bridge. Even sanding down the existing bridge is as much work as buying a new adjustable bridge but still having to do the same work. The only saving grace would be that I wouldn't ruin the existing bridge so might still give it a punt anyway if the worst outcome is losing £30 and a couple of hours.
No grooves to speak of on the fingerboard, more or less cosmetic/maybe a millimetre difference and at this point, I can't really play upright bass as is and I don't yet have playable strings so that can wait 😅
The bridge is my main concern as I'm certain the strings shouldn't be that high and if I'm ever gonna get to grips with an upright, the damn thing needs to be playable. I mean, I'm never gonna be Paul Chambers but I'd like to at least be able to attempt 'So What' and feel somewhat in control rather than like I'm fighting metal snakes!
I never wanted to sell it anyway, just wanted an idea of cost to restore vs buying one so with Jake's strings and maybe a £50 punt on shaping a new bridge, I'm hoping I'll have a playable bass before long!
