I wanted an upgrade to my 35" 5 string (that I didn't like to take below Ab due to muddiness), and I play in a band tuned to F#0, so wanted a 37" bass, at a £1-1.5k range. It was a choice between this and the Spector Dimension. However, I also wanted a 6 string so i could have my F#, B and regular EADG to have everything covered by one bass. This bass allowed me to do that, looked stunning (as did its sibling the 866MS), and sounded great from YT videos. When I was measuring it, the scale length is actually 34.5
-37.5", so you get a 1/2" extra free if, like me, you are looking at this to handle F, F#, or G.
I have been playing this as my main instrument for a couple of months now, so feel qualified to speak on it.
SOUND: The range of tones I can get out of this thing is exactly what I wanted, even without running intricate signal chains from it. The T1 pickups are so responsive to string attack and tone control, I have not felt need to adjust their heights from stock. I use mainly fingers and slap with some pick, and I have felt like I easily get the tones I want to recreate. On my simple overdrive preset, I can go from a heavy djent slap riff to a bluesy muted scale run and it cuts right through. The pickups still maintain their bite and body on the thickest three strings way past the 12th fret, which was an issue on my other bass.
I have swapped the stock nickel strings for stainless steel (be mindful at this scale, you're limited to Dingwall strings or custom ones from Newtone, the D'addario Super Long isn't long enough for the 6th string), and again, I have such control over my tone.
PLAYABILITY: In terms of weight, it is 4.6 kg / 10 lbs which is not the lightest bass, but it is finely balanced with no neck dive. The neck on this is super thin, I have short fingers so was concerned about playing it comfortably, but the design has made adapting to its width and the multiscale really natural, and relearning fretting hand (and thumb) position has made me evaluate and really improve my technique. It holds its tune super well, even after a heavy slap practice with lots of pops and bends. Out of the box, the action was low (2-2.5mm), and have been able to drop it to 1.5-2 with only a minor tweak of the truss rod, and no fret buzz at this low level, incredibly happy with the build quality for that.
DESIGN / BUILD QUALITY: The style choice of this is stunning, I love it, and it catches attention. I will say, and this is why it dropped a star, the nut is slightly out of alignment over one edge, and the edges of some frets could have been smoothed off more. A minor gripe, but disappointing from an instrument at this price, but the rest of the build is fantastic quality. The routing for the bridge of pickups is tidy, the finish and detailing of the body is beautiful. Personally, I think the gray-brown stain hides the beauty of the poplar burl, and have sanded and restained parts of the wings an amber colour (which might make you discount my judgement in this entire review).
OVERALL: For the price, for the look, for range of sounds and responsiveness of the pickups, for how comfortable it is to play.. I am very very happy with my decision, and this is going to be my main bass for some years.
