I've got an MTD 435, serial #81, that I just picked up from TB'er mrcircle (great guy, BTW). I love the sound of the bass, which was made in '96, but the output is very low. Apparently, it's just the fact that the earlier Bartolini's Mike used had a lower output than the modern ones. I just wanted some more opinions as to whether or not I should send the bass to Michael Tobias and have him replace the older pickups and preamp for a higher output version, or just keep it as is and crank the gain on my amp, which does the trick also. Looking for fellow TB'er advice. Thanks in advance.
