I have a MIK Kingston Heir and a USA Super - both 4 string, 34" scale. They are completely different tone wise, but they are that way for a reason.
The Heir is Ash, Flame Maple veneer, maple neck, rosewood fingerboard. It's a killer combination of Jazz and MM, quite versatile for lots of different music tastes. Can be treble-ly, mid-focused, or fat; kinda depends what you need and how you set the eq...but it does have a piano-like tone to it. I love it, got it new 15 years ago, and don't plan on ever selling it.
The Super 4 is Ash, Maple Neck, Roasted Bird's Eye Maple Fingerboard. It's very Mid/Treble Focused because that's what I was looking for in the instrument. However, it will fill the bottom end in if you want it to. Again, I will never sell it.
The pickups and preamps he uses definitely allow the wood to do the talking. Mike has said many times in the past that even though you plug them into amps, they are acoustic first. The build quality, materials, and attention detail are all there. MTD Basses are incredible instruments...but I might be a little biased.
These two MTDs are going nowhere but to sessions and gigs with me. I did have a MIC CRB 4, and a MIC Kingston Heir 5 at one point. I never connected with the CRB (could be the P-Bass sound, I'm not sure...), and I could not, and still can't, get used to a 35" scale 5 string, so I sold them both.
