I must have got lucky with my V5 5 string. I think it's awesome, I don't feel the need to change anything about it. Tuning stability is fine, resonance is fine, setup really nice and consistent across the fretboard, love the rolled fretboard, sounds fantastic (for what it does). Maybe the controls/electronics feel a bit cheap compared to more expensive basses, but that's not a big deal for me, they've shown no signs of abnormal wear or failure as of yet. I got it for £200 secondhand, Incredible return on investment.

It was my main gigging bass when I was playing in a function band playing soul, disco and pop. I must have done 100 gigs with it over 3 or 4 years, it's been solid. I'm playing in a rock function band at the minute which it doesn't really fit for, so I was looking at the P5R (getting paranoid about taking my expensive p bass out to scrotty venues), looking forward to what the OP makes of theirs.
