I currently have 3 Maruszczyk basses:
- A fretless Frog 5P 34" with a single Bassculture 38HB, purchased from Public Peace's stock
- A custom Frog 5A 32" with two Delano Times Square pups and a John East Uni Pre 4 preamp
- A used Jake 5P 34" with a Delano P (large poles) in the neck and a Delano MM (large poles) in the bridge
It is important to know that I do not have extensive experience with different types of basses. I played a Fender Jazz 4 string for many years prior to purchasing #1 as a second bass, and then #2 replaced the Jazz and #3 came later. I have played other models in stores, but I don't feel like I have a wide variety of basses that I'm familiar with and can compare to Maruszczyk. (Side note: the one bass that surpassed everything in the short time I played it was an F Bass BN 5 string)
That said, the Maruszczyk's are extremely comfortable, especially the Frogs. That body shape fits mine really well, and the necks (satin/matte) are a night and day difference from glossy Fender necks. All of the basses are quite light as well, which helps with my bad back. They all sound great to me, and I love the versatility of #2 and #3. Build quality is excellent.
For me, there has only been one downside: the B strings on #2 and #3 have been a pain point. I have been trying different strings with different gauges (tapered seem to work best), lowered the pickups fairly low, set intonation, checked witness points, etc. However, the B continues to sound like a dull thud and out of tune with the other strings. I know that sounds like an intonation issue, but I use the same method to set the intonation as the other strings and those are great. As I go up the fretboard I also get a bit of a chorus effect, which I've read this is usually a pickup height issue or twisted string, but I've checked those things multiple times. This could be my fault or a lack of experience with Bs, for sure, but I've been tinkering away and can't seem to get it right. I don't know if this is common with 34" or shorter scale Marus, though I believe @Barticus has been happy with his Bs so ¯\_(ツ)_/¯
Overall, they are fantastic basses and I feel lucky to have 3 of 'em!
