It’s ace. The plan was essentially a bass which can look relatively “standard” whilst being anything but. In terms of wood specs it may look plain but Holly is an expensive luxury, and the ebony and bloodwood blocks board is up there with the higher options you can go with.
Electronics-wise it’s basic but has the potential to be added to (not likely that I will, I like passive basses!), but with the pickups and coil select there is immense variety. As an overall package it’s an absolute delight and perfection for me
Edit: should add my 2 cents on string spacing. I’ve had 5 strings from Alan with 19mm, 17mm and 16.5mm spacing, and other 5ers with 18mm. My fave is definitely 17mm, and I have to say I
delighted that I chose this for the RetroB as it falls under the right hand beautifully for me. If string spacing is a prime requirement, stick with that. The MC/Uber spec is great but you won’t be left wanting for tonal variety with the B series pickups and a standard preamp at all.
