hey guys I am building a guitar. The problem is that I have not got a clue what pickups I should use everything I have listened to sound kinda bland. I play jazz so I want a really warm even sounding neck pickup. As far as the bridge I play metal so I want something that is thick, warm with nice mids, and if possible decent treble. (I don't want a overly bright metallic sounding pickup). Also does anyone know a wood or combination of woods that wood be really versatile. Also in a solid body guitar does the wood matter when plugged in. Also does any know about scale lengths.

Thanks for any help you give.
