Im no tech person but its really quite easy to install new pickups. Just a good soldering iron and a bit of common sense. oh and you tube .
This bass was originally a great bass, when it comes down to construction. Had Delano single coils, which weren't my favourite. Now it is just superb. Its articulate with the Delano pre, with a fantastic low end from the Bart's. I will be changing out the Delano. its way to clean for me. Im thinking of maybe a Bartolini 3 band. Or an East. I don't particularly want a Marcus tone as I think a lot of it comes from the 70's spacing anyways, and this bass hasn't got that. I just want a fat, punchy, growly tone. Ok that sounds like a Marcus tone. he he. Im half way there with the Barts and the DR fat beams. I just need a different preamp
Its fabulous to play. The neck reminds me of the Lakland 5502. The instrument is light which I dig. All in all these instruments are out there. Its not my favourite jazz bass ever. That goes to the Sei, but its pretty close, seeing as the Sei is over twice the price new.
This is a keeper, just fabulous instruments are these Maruszczyk's
