I need some schooling from you guys... I have a V4 and a M5V, both ash body with maple board. My V4 has a quarter-sawn neck, and the M5V neck is flat-sawn. I have DR nickel Sunbeams on the V4, and DR nickel Lo-Riders on the M5V.
I have the neck relief set exactly the same on both basses (at .012"), and the action is set very close to the same on both basses as well. I like pretty low action.
Here's what I'm curious about... My V4 is effortless to play, and it's so easy to press the strings down anywhere on the fretboard... It really just plays like a dream. My M5V plays great too, but it always "feels" like the action is higher, even though it's basically set at the same measurements as my V4. It takes more effort to press the strings on my M5V, and sometimes feels like I'm having to work a little harder to play it than the V4. The action is as low as it'll go without buzzing, and I really don't like how it feels with more neck relief than I have set now.
Does anyone have an explanation for that? Why does the action on the M5V feel higher and more difficult to play, when both basses have the same adjustments? I'm wondering if it's the 34" scale versus the 35" scale, the quarter-sawn neck versus the flat-sawn neck, or the Sunbeam strings versus the Lo-Rider strings.
Regardless, the M5V still plays fantastic, better than any factory bass I've ever played. It's just not quite as effortless as my V4.
