I have a Fender BG-31 acoustic bass. It's at least 8 years old and still has the factory original strings on it. My main concerns are: 1- What can the neck/bridge/body/frets handle? I don't know anything about the truss rod in this thing (can the truss rod even be turned both ways?) So I'm worried about string tension and fret wear, etc. 2- Scale length - It measures 32 inches from the bridge to the nut - will there be any problems if I uses standard 34 inch strings? 3- String material- I'm not sure how the pick up in this thing works, can it handle nylon strings? The original strings look like they are made out of copper to me (possibly bronze though?) 4- Other thoughts/advice you might have. I feel I have a pretty good understanding of strings when it comes to solid-body electrics, I'd just rather not experiment on this bass and end up ruining the neck. I wasn't able to find a product page for it on fender's website, so here's a link to one on Musician's Friend. (assuming the specs haven't changed since mine was manufactured): Fender BG-31 4-String Acoustic-Electric Bass: Shop Bass & Other Musical Instruments | Musician's Friend This isn't my primary bass, but I do use it in a variety of settings, both acoustic and plugged in. Thanks!
