There are not as many threads on this bass guitar as I would have expected. I've read just about all of what's out there on TB & watched several YT reviews...etc. I haven't run across one to try out yet, but sure do want to. Seems like a lot of bass for the price & potentially a great platform for modifications (similar to the 55-01 by Lakland - I prefer the 18mm string spacing on the 605). Do any of the current users feel like upgrades would make a big difference in the tone [hardware (bridge &/or tuners), pups, &/or preamp]? In addition, any updates from what's already been posted in other threads, especially wrt comparison with other basses you've owned, would be very much appreciated. Thanks in advance - JD.
