Rather than dropping $1500 on a used Wal, I was wondering if there was anyway to get a similar tone by modding a pre existing bass with a pups swap? I am not looking for an exact duplicate or anything. But I was just looking at the pickup design and wondering if the DiMarzio Will Power Neck/Model One or a Darkstar would do the trick? It would be replacing a P styled pickup, pretty much in the middle of the bass. Thoughts?
