Hello everybody! I really need your experience with these basses M3 and TRVX 504 I play a Sire M7 fretless which I love, playing it with Dadarrio or Thomastik flatwounds.. My fretted bass is a cheap Jazzbass copy. Now I need an upgrade. I really love the sound of the M7, especially the middle frequency. But I am not sure if the M3 produce the same lovely sound. I don´t need the two switches the M7 does have to control the humbuckers. The M3 is much cheaper than the M7 but does it sound cheaper, too? The Yamaha TRBX 504 seems to be another fine bass for the money.. And it means quality and durability! Do you think he can rival the M3? I am playing Jazz and some Pop music, no slapping, just fingertips.. Also I prefer flats even on a fretted bass... What do you think? Sire, Yamaha? Have a nice day!
