View attachment 2748145 This is my 3 pick-up Fender Jaguar Modified Bass. I prefer the original look of its manufactured setup. The bottom knob is still the tone knob. The toggle switch is a three position for the top 2 pick ups (Neck and P-Pickups), Switch in position one is the neck only, position 2 is neck and P, position 3 is P-Pickup only.
The 2 top pots are volume knobs. Top most pot is the Neck And P-pickup volume knob. The pot below it is the bridge pick up volume knob. Pricing was one of the determining factors for my electronic selection and space in the existing cavities of the original bass body.
A good amount of wood was being taken out because of the new pick-ups with the addition of the third neck pickup. I play in several different styles like most of us but I wanted to be able to retain some traditional sound but play and experiment with my own versions of new sounds that work well also.
She was designed to both cut through the mix or disappear in the mix with little to no adjustments necessary which is why I went with the simple controls and the 1/4 pound Seymour-Duncan pickups. I had a clear vision for it, so I would recommend picking those things that are particular to you and your playing style as well as Genres you plan on playing in. If you need high versatility then design it for that. Build what you need but in order to do that you need to first look at yourself and what you enjoy playing. For reference I play Blues, Jazz, Latin, Metal, Rock (all versions), Pop, Reggae, Electronica and Hip Hop.
Hope this helps. Have fun building your 3 pickup bass!
May the Bass Be with You!
