Ok, first you have to TRY to make a pig of either type sound muddy. With any sensible amp settings both are crystal clear. Heavy as hell, and crystal clear.
As for comparison, EQ wise the miracle man is no slouch in the bass. The pig has a reputation for it, and deservedly so, but a lot of its heaviness is in the mids for both the A5 and C WP.
All have comparable lows, I cant really tell you for sure which is more of less as I've never had the any of the CWP, WP or MM in the same guitar. All plenty of kick though.
As far as the character of the lows goes, the MM and CWP are quite comparable as they're both sugically tight.
The MM and CWP have a smooth mid, the MM being a little scooped with a nice kicking low mid left quite prominent. The pigs mid response is more even (making pigs sound HUGE)
In the highs all are completely clear and articulate. The sharpest sound and most highs is in the MM without a doubt.
The biggest difference in character of the sounds is in the gain and compression. The CWP has more of both.
