Ok, once again (and as I mentioned in all the 100's of other anti-slap threads)........
Where are you guys hearing all this 'bad, horrible sounding slap bass'??? I have never heard any 'professional' band's bassist play any slap bass that sounded bad! If you guys are talking music stores, sound checks and NAMM, yeah it can get annoying but in the context of a pro performance.......it all sounds pretty good to me.
If you don't like Marcus, Victa and the like, then please stop listening to them and critiquing them! They are pros and it's how they make their living! Lastly, depending on your demographic and music listening habits, slap bass is still quite prevelant in all styles of music. You may not hear it on the radio but there is a LOT of music out there (GOOD MUSIC) that doesn't see the light of day on the radio. If you want to gauge your opinion on what's on the radio.........well then, you're missing out! If you're a rock or metal head, and don't listen to much else, you don't have the authority to declare any style 'dead' especially if you don't listen to it, play it nor enjoy it!
