Hi Amigoz2k,
I am going through a similar thing. I have a TRB 1004 J and have found that the pickups are EMG 45 sized.
There are a few options, Bartolini, EMG, Seymour Duncan SSB and quite a few others.
Any pickup that uses the rail design is a good option as Yamaha use the same size Pup for there 4/5/6 string TRB's.
I have recently upgraded to an EMG Pre and JCSX and CSX Pickups. Still waiting on the parts so can't judge on the sound just yet.
Alot of members have felt the pickups were great but that the Pre was not the best. If you are unhappy with the sound I would maybe start with the pre.
As I have stated several times in different threads, I have found that the Body,neck and playability is second to none but all the other bits and pieces are the difference between a TRB and a BB2024 or similar.
I am currently doing a giant upgrade project on a TRB.
Regards,
Thanks BluesMan 84 for rapid response and I 100% agree with you to try a preamp first .
anyway I`ll wait for you completing your project to tell me more about the difference
wishing you the best
