OK from the sound of it seems that it would need to be re-UV'ed Here is a tutorial from CGCookie CGC Classic: Modeling and Texturing an Electric Guitar it is a bit dated but it also includes how to UV unwrap it and that might give you some guidance in Re-UVing the model you have but you might need to retexture it also so really depends how far you want to delve into this project unless you want to model one for yourself from start to finish
