Wow, it's been a long time since I posted in the corner! So I've got this Gretsch Junior Jet -- one of the early pre-Fender Korean-made ones with the coveted TV Jones-designed pickup. I love the size, it fits in a guitar case, and sounds great but what I don't love is the weight -- 8 pounds, 3.8 ounces. I've thought about chambering the body but I wanted to get some feedback first. Now, this isn't a question about difficulty or method. I've built instruments before, most of them chambered because I prefer lightweight bodies, so I know I'm capable. What I want to know is simply what everyone's opinion is. Surely some will say "you'll destroy it's value so leave it as is!" Others will probably say "it's your bass, do what you want" or "why not buy a lighter bass or build a chambered replica body?" 1) I have a lighter bass -- a vintage Gallan violin bass and a P-bass with a basswood body. 2) I understand the value concerns, however I don't plan on selling this bass and even if I did, once finished, you wouldn't even know it's chambered unless you're familiar with Junior Jets. 3) Yeah, I could build a new body but frankly I don't want to. In the past, many moons ago, I had a solid alder-bodied Jazz clone that felt like it weighed a ton compared to my basswood P-bass. Took the body to a local cabinet shop and had them run it through a planer, finish and all, to remove 1/4" off the top. Then I chambered it, applied a spruce top, rerouted the pickup and control cavities, refinished, and voila. With the Gretsch, however, I'd plane the back instead because I want to keep the top's original burst finish intact. The back is solid black - much easier to refinish. I'm still thinking about what wood to cap it with. Something lightweight yet strong. Ash perhaps? Anyway, that's my rambling. Let me know what you think and we'll see if this thread becomes a progress thread or not.
