Regarding weight, here are my $0.019:
Cats refer to tone related to weight, and when you are talking one of Mike’s basses, most of us do associate the construction with tonal variance. Though, the reality is that perhaps it’s more of a “feel” variance vs actual tone; because the different constructions may “sound different” when you play them; but, when you listen back to tape, the differences are a bit less apparent. So, let’s not get caught up in this dichotomy.
IME, heavier instruments tend to have a more solid basis to the tone. So, players, like Marcus Miller, who want that super solid feel because of their preferred style, go for the heavier instruments. For that purpose heavier = better. Lighter instruments tend to have more sense of resonance in the feel and tone, so players in the Jaco/pizz school or chordal players looking for that classical guitar resonance look for lighter instruments. For those players lighter = better. And I’m sure there are other prefs; but those are a couple of boundaries.
Mike is aware of these preferences and will work with his player/ customers to make what they are seeking. This is the advantage of commissioning a build with Mike and working with him. But, you need to know what to ask for.
Ultimately, there is no “best.” It’s on the player to understand the preferences. I like my basses in the middle of things around 9 pounds, and that’s what Mike is working on right now. Can’t wait. BTW, both Mike and Daniel are fantastic cats to work with. Real treasures in our community.
