The Sam Ash near me has the MK Sojourn, short scale Taylor, Ibanez PNB and Gold Tone. I've compared them several times, and I have to say the MK is at the bottom of the list in terms of unplugged tone, volume and presence. It has a really weak, hollow tone. Maybe they shouldn't put that large hole in the side. Definitely worth a hands-on comparison if you can before putting money down for one. Of the short scale basses I've tried, the Guild and Taylor have the best feel and sound, but the Ibanez PNB is a better value, not far behind. (Still waiting to get my hands on the Ibanez AVNB1E or B2E - hoping one of the local stores will get one in sometime)
This is with the caveats that I'm not a super experienced bass player, and also with 4 different sets of strings (some with visible aging damage and spots) a fair comparison is not easy. But to my ears there is a significant, noticeable difference and the MK is far behind the others.
Good stuff. Thanks.
