I have a Tom Clement fretless five string that I picked up from a fellow TB'er. The thing is a MONSTER of a bass, so I recommend anyone looking for a groovy mama jamma to hit up Tom. Ahem, NEVERTHELESS, I am not too hip on using the low B string, and if I do it is typically in a region that is on the "E" string. Because of this, I am looking into putting some Thomastik Jazz Flats strung E - C on this bass and I am curious to know if that is potentially dangerous. My reasons for asking being: A) Changed tension could cause neck warping? B) Nut issues? C) Anything else that I am unaware of! Any help is majorly appreciated! Thank you for your time! -Guim.
