Saw an ad in an old Guitar Player; are they any good? I was considering getting one if they're still available or making one myself. I may be wrong but the strings on my old 4 string J bass rang longer than on my new 5 string. ( both from the same manufacturer; Washburn, Lyon series.) That may be due to the body beeing made of very poor material. Would a new body help? I was looking for a simpler solution. Thank you. PS; Great forum, by the way!
