I own a usa P bass with the S1 switch and its great, I love it. However many years ago before I owned the usa (my bass at the time was a Squier P bought new in 97) I was in a guitar shop on the look out to buy a new amp.
The guy in the shop asked what type of bass I played, I just said a precision and he handed me a usa p. Plugged it in for me and I thought Yes here we go. It was terrible, to my hands anyway. I was really disappointed that I'd got my hands on a usa p and it felt rubbish. I asked if I could try something else and tried a usa jazz which was miles better but the neck was too thin for my liking so tried a mexican p which was no where near as good as the jazz but better than the usa p.
I then saw this red bass, I thought it was a really ugly bass(just my taste-sorry) but thought i'd try it anyway. It was amazing better than all the others but maybe just edged by the jazz. There was no price on it so I thought this one must be really expensive. At the time I had no idea about this brand of guitars so I asked the guy how much it was. He said he didn't know but he'd go and find out. I thought "I'm right, its gonna be pricey. He returned and it turned out it was an Ibanez gsr 200 at £179. Ha I nearly fell off the stool.
Eventually I guess I got lucky and bought a usa p off ebay without trying it first. I have had a few back up basses but no only have the usa as not been playing bass so much recently. The two best back ups I had were a 51 reissue and a Squier classic vibe 60's p. The fiesta red one if anyone is interested. Tried some jazzes and even tried a Hofner bass. Think i'm gonna get another classic vibe p as back up now i'm playing more bass again.
