The £820 I paid for a Pro Precision a few years ago wasn't massively underpriced but it was a good price for the time.
Its value for me was massively enhanced though when it turned out that it was a total player; light, resonant, perfect fit & finish and already sporting a few pre-loved blemishes.
So good in fact, that I culled the herd in the knowledge that I'd be hard pressed to find another bass I enjoyed playing more.
In a roundabout way, it's saved me a fortune.
(I still can't help but occasionally pine for a Jazz to go with it)
