I have settled on a plan for a bass. I will be using the Tarr model bass from the selection of plans produced in conjunction with the Chandler book. I have started the layout of the MDF mold and after drawing it out and seeing it in life size, (as well as looking at the plan itself) I don't really care for the shape. I want to modify it slightly. So, if you look at the two illustrations below, (from the actual plans) you see that I the original has higher, more squared shoulders and my modified shape calls for steeper shoulder with a more feminine look. To me the aesthetic difference is huge, but I don't want to kill the design for the sake of looks. So, when I tweaked this in photoshop, I just stretched the top to steepen the shoulders. It reality I would have the option of stretching the plan or simply cutting the shoulders in for a overall smaller upper bout. For those willing to answer, I ask: What are pros and cons of each approach? Specifically, would either approach compromise the general design to the extent that it might be structurally questionable without other significant mods. I certainly don't want to stray from the general model so much that I have to significantly modify the existing supports, bass bar, FF hole placement, etc. If so, I'd rather just build the Chandler Tarr model as is.
