I enjoy my Squiers. As a retired novice bass player who plays in his living room, my experience with them has been overwhelmingly positive. Strangely enough, I migrated TO Squiers after first owning a gorgeous 2011 '75 AVRI Fender Jazz (natural). I sold my last vintage motorcycle (back problems), and after lurking at TB for months, decided which kind of bass I wanted, and found the aforementioned AVRI Jazz listed at Bass Northwest for a very decent price. When it came in, it was drop-dead gorgeous and so minty, I couldn't tell it from new. Over the next few weeks, I might have played it for a couple hours, tops. I was intimidated at the thought of putting a single scratch on it.
This became a problem for me. Being too paranoid to play it, I wasn't getting any practice done. After receiving a gift certificate at a big box retailer, I took a chance on a Squier VM Jaguar. On sale, the final cost was such that it didn't matter if I used it as a boat oar. I played it with abandon, and started enjoyed practicing. After having ordered one Squier sight unseen and unplayed, I took a chance on a VM 70s Jazz, to take the (cosmetic, at least) place of the now-sold AVRI Fender Jazz. I was not disappointed. To my untrained ear, at my level of playing ability, the VM Jazz sounded as good as the now gone AVRI Jazz (especially with Fender 9050 flats).
This was followed by another Squier, this time a VM Precision (amber). I liked being able to explore the different tonalities between the various Fender (Squier) designs and have a choice of which to play, given the very affordable prices. I followed suit with a CV Precision 50s, then a VM Mustang, and very recently, a VM Telecaster. I have made modifications on a few of these. Many have simply had a string change. All of them are keepers, as they all bring something different to the table. None of my Squiers have exhibited problems with construction, finish quality or grade of hardware used on them. Most importantly, they all sound good to ME.
I mention all of this just to put into perspective MY personal experience with Squiers. Obviously, someone making a living as a musician probably has other priorities. Some people have unfortunately bought a Monday/Friday Lemon that had "Squier" written on the headstock. It seems to me that it is never a good reason to proclaim that an entire brand is somehow inherently defective because of one experience. The OP claims that "every" Squier he owns fails him at some point. That would make him extremely UNLUCKY in my book.
OTOH, I consider myself to be EXTREMELY lucky to be playing bass at this very moment, when it seems that the Squier brand is making basses of a quality that far exceeds their cost, and is introducing new models at a breathtaking pace. So for me......
...........Vive le Squier!
