i am currently playing an epiphone thunderbird V pro. it is doing ok for the moment, but i am looking to upgrade. i have noticed that any bass with more than four strings is harder to slap and pop on, but am also looking for six strings for extended range when playing meshuggah, nociceptor ECT. i think that i will buy two new basses to replace the one i have. one four string for jazz, funk and slapping and a six string for metal, mathcore and Djent. can anyone recommend any basses for these two categories. i have looked at the ibanes BTB406QM but i am not keen on the headstock. any help would be much appreciated.
