The tone equation is simple:
[1] the more expensive and rarer the tone wood, the better the sound
[2] the more vintage, the better the sound
[3] the more the bass looks like a coffee table, the better the sound
[4] add "Fodera" on the headstock to multiply your tone by 10
Tone = [1] x [2] x [3] x (IF [4] = true, 10, 1)
