Here's the link to Fender's description here.
The upgrades are Schaller strap locks and a Gotoh 201 direct replacement bridge. Link to the bridge specs here. I'll include the original bridge and strap buttons. These basses ship with a Fender deluxe gig bag. This bass has never been gigged and has probably left my house twice. It's in great condition. Has the Fender USA electronics and noiseless pickups which sound great. Has knobs for bass, mid, treble, volume, and pickup fader. I bought this new from Indoor Storm in Raleigh, NC about a year ago. This wasn't a GC wall hanger. Great bass for the money. I'm only selling because I never really play it and I'd rather buy guitar or drum gear. I can take more pics if needed. It's not as yellow as it appears in the photo. Looking for $450. I accept PayPal. Sells for $649 online.
