I just put together a pretty badly messed up black Madeira bass,through research I see they are japanese Guilds?my friend gave me a broken up Hondo and this was even worse but I took the P style pickguard off and finished the Madeira,it actually came out nice,I had to take a j bass p/u cover to fill a hole that was left and relocate the bridge but it is a string height adjustment away from a gig.I have not read to many articles or threads on these instruments it feels OK to me but who has experience with these instruments?
