These were made by Modulus in the early 90s for bassist Brian Bromberg. I bought it directly from Peavey with the intention of getting luthier Andrew Drake to build a custom body for it. I spoke to Andrew about it and after our conversation and sending him pictures he can replicate the exact same body as the B Quad. If your not familiar with Drake look up his YouTube videos he is an extremely skilled woodworker and luthier. So why am I selling it? Simply put: I have an addiction buying to much gear and recently bought a P bass from Drake so I’m feeling tapped out right now and honestly don’t have the funds to build this cool B Quad project. I think it would be a rare chance to customize your wood choices for the build and use flamed maple to match the peg head. These do not have a truss rod it doesn’t need one, the nut is a jazz neck profile 1.5 inch. Free shipping included in the price.
