Hey ladies and gents, I now feel comfortable to voice my opinion on my Marchlewski that I recieved last wednesday. I'm going to go into a lot of minutiae about the bass, so I hope it doesn't bore you. Specs: 5 String headed/less Ebony fingerboard bound with Padouk Walnut Body Quilted Padouk top Wood pickup covers Neckthrough ABM Single bridge tuners Nordstrand Fat Stack pickups Demeter 3 band pre-amp Ebony Knobs Construction: The bass is put together very well. Most glue joints are very tight, the accent laminations are pretty uniform and there aren't any raised spots on the back of the neck between laminations. There are also 26 frets, when I thought I ordered 24; so thanks Jake! Pro: Meticulous sanding/wood joining, feels very solid Con: 1 slight top imperfection; negligible. Sound: The sound is very, very clear. It's modern sounding in that you can hear all the notes, but not in the abrasive-treble-no-lows sense. It's a very open bass that requires little EQ. Carey Nordstrand warned me at NAMM that there might be some signal to noise ratio problems with the Demeter preamp his Fatstacks, but the only problem that I've encountered with it thus far is when I solo either pickup there is a slight hum; not as bad as I was led to believe. I usually play with both pickups on and flat, so it doesn't really bother me. The Demeter preamp is a great sounding preamp: it's very subtle and the boosts don't muddy up the tone, if that makes sense. It's all very usuable. The sound is exactly what I wanted. The control cavity is shielded and wired very well. Pros: It sounds the way I wanted, clear and articulate without being harsh. It cuts without being overly mid-rangey or abrasively, a very supportive sound. Cons: Slight hum when pickups are soloed. Comfort: This bass is one of the most comfortable basses I've ever owned. The headless design prevents any neck dive, so I don' have to exert any left hand/arm energy to keep it up. The body fits me very well and my right hand falls in my ideal plucking position. It's like this bass was built for me. I mean, I know it was, but I'm talking from an ergonomic point of view. The padouk neck is exqusitely carved and smooth; my favorite neck wood and shape to date. The 0 degree radius is also quite great, it's very quick. I have no qualms about anything as far as comfort goes. I will say again that this is the most comfortable bass I've ever owned. Pros: Feels like it was built with my body in mind. Well executed design. Cons: None. Summation: This is the best instrument I've ever played. There are a few small things about the instrument that could be improved, but as it stands right now, this bass rivals many of the boutiques that I've played for half the cost. Jake is also one of the most accommodating and kind people I've come across in the Custom Bass realm. He didn't shoot down my headless idea with an "oh, that's dumb" or "oh, I won't do that." He accepted it and my quirky requests and executed them beyond my imagination. In closing, Jake will probably become very reknowned very soon and I'm going to need to order my fretless from him soon!
