So I rented a bass from I.U. today to play in the summer orchestra so I wouldn't have to screw up my jazz set-up on my one bass. I was excited about having two basses finally, one each dedicated to jazz and to orchestra playing, but the school bass is predictably craptastic (the label says "Baxter and Northup Orchestra and Band Instruments, Los Angeles, CA," so I have no idea who/what made it). Here's the thing: I noticed that the (new-looking) bridge was bowing way forward, toward the nut, so I loosened the strings to adjust it, and much to my surprise the bridge seems to have been installed backwards! The flattish end is facing the fingerboard, and the curved-ish end is facing the tailpiece. So the slight natural curve of the bridge is, well, going the wrong way. I toyed with the idea of turning it around, but of course the curve didn't match the fingerboard, the string slots were arranged backwards, and the feet didn't sit flat on the table. It was cut backwards from the beginning. So I left it as-is, and it looks ridiculous. My question: does it matter? I imagine it does, and I'll take it back the school's shop for a number of reasons (the student who screwed it up needs to see it, plus there's daylight coming in through the seam in the back, plus the summertime action on the non-adjustable bridge gave me sharp pains from twenty minutes of playing, plus the end-pin is too short, plus it sounds like it has a sack of wet mortar inside it, plus I just plain don't like the looks of it; the neck and tuners are good, though...).
