I'm looking for an older passive bass as a backup. My main bass is a Peavey Cirrus. Which of these two basses do you think is the most playable and has best tone; Peavey T-40 or Yamaha BB2000? I realize they are both heavey guitars. I owned a Gibson Thunderbird II for a while and it was a heavey beauty. I play mostly jazz, blues, contemporary Christian music.
