Played a Maruszczyk at the London Bass Show this year and didn’t get the fuss, though definitely not the worst bass I’ve ever played.
That would be a Warwick FNA Jazzman which was a superb bass then, when I needed to borrow it for a gig, my friend changed the strings to these horrendous thin plinky things and the bass became unplayable. So really the strings rather than the bass but it’s haunted me haha
