I don't think there is that much of a correlation between price and quality, certainly not in the used market and that's where I operate. Over the years, I've had some very expensive instruments, plenty of much less expensive instruments and those inbetweeners. In my experience, the price is often more associated with the brand name than the quality of the instrument. My favourite basses over the years have usually been picked up used for around the 400-600 quid mark, often less. I've bought much more expensive instruments, going on myth and hype, which were utter rubbish, not just as an instrument but in terms of build quality too. When you've been around long enough, you see how the price follows hype rather than quality. Did Japanese Squiers only become good in the last couple of years? The prices now compared to 10 or 20 years ago, relative to other instrument prices, certainly suggests so. And then there are 70's Fenders... wow 😂
