Hello all. I'm a senior in high school taking on a very big project. I'm trying to build a j bass from scratch. My woodshop instructor is going to be helping me with this, but I have to provide him with information about the bass. I need dimensions, and images and measurements and all that jazz, but I have a ton of questions. He's going to be cutting it out Ash and i'm going to need to buy the neck separately on my own time. Here are my concerns: 1. Where can I get this information? I need to give him the measurements of the body, and how to cut and rout it. I've never even owned a j bass, so how do I get it? It needs to be spot on, or he might mess it up and i'd be very upset. 2. I want to place a fretless neck on it. Thing is, I want a full 2 octave fretboard on it (24 frets, but no frets obviously). How do I know when a fretless bass has space for 24 stops, and does this change the measurement for the neck pocket? 3. Does it matter what preamp I buy for the bass? I want a 2 band preamp (Volume, Blend, Bass cut/boost, Treble cut/boost). Where can I get this type of preamp? I know Aggie does a 2 band, but it's boost only. Does it change how I would need to rout it? I also want the standard 4 knobs and control plate that sits on the Fender J basses, would it matter what preamp I use with that? 4. Bridges. What bridge would be best for this? I was thinking a Gotoh 201 since it's pretty standard and would probably be easier to replace down the line, but any other one I should look at? I also want 19mm spacing, will this affect anything? 5. Dimensions. Where do I rout the pickups? The front control plate? The bridge, the knobs, etc etc. I know these measurements have to be precise, so how do I get this info? I need to print out designs have specs so I can give them to my instructor. I'm completely new to building a bass, so I need some big help on this. 6. Pickups. I was thinking SD Q-Pounder pickups, but I don't know what pre-amp i'm going to be using with it. Would it matter what pickups I use, or do their dimensions change? All in all, I'm not doing anything fancy as far as electronics go (standard 2 band EQ, JJ pickup set), but i'm just afraid that i'll mess this up somehow and I'm unsure about all this. I need all types of dimensions and mesurements, front and back. Any help is greatly appreciated. Thanks.
