On a review of a Squier Jaguar someone was like “And there's 3 knobs for the 3 pickups.” I thought about how stupid that sounded cause there IS NOT 3 pickups… so, all in all should beginners actually be able to write reviews if they don't know what they're talking about? With my old Jaguar that'd be like me saying there's for 4 knobs for the 4 pickups
I'm sure there are a lot of newbies out there who aren't as interested in learning the language of guitar and bass as learning to play guitar and bass. The reviewer you mention sounds like one of them. It's no big deal. Not every musician can read sheet music or knows musical theory, but that doesn't mean they can't play the hell out of their guitar.
You didn't say the Jaguar was a Bass, Jaguars have two knobs, two roller knobs, four on/on slider switches and a toggle switch but the Les Paul Junior has one pick up and two knobs and blows the Jag away. Oh and by the way, yeah, everyone is entitled to an opinion
