I just discovered that I would like to downsize and keep about three or four 5 string basses with an 18mm bridge. Maybe a 17mm if the neck co-operates. What are some of the 5 string basses with an 18mm bridge? I think that the Ken Smiths 5's, Roscoe Beck 5 (just maybe a 19mm), Yamaha TRB5's, Lakland 5501's, Alembic Epic 5's, Ibanez BTB 515's are 18mm but I'm not 100% sure. I think that the Pedulla Thunder basses have the 18mm bridge also. How about the Zon Sonus 5/2? Does anyone have that bass? I was told once it was a 17mm. I have some of these basses but they are not within my immediate reach....except for the Ken Smith.
