I really like the Sansamp Para Driver for my reggae tone, gets a nice thick sound and is a fairly dark sounding preamp already. I just got a VT Bass though, so it might be my all-around sound pretty soon.
To the OP, if you end up not liking the tones you can get from the Peavy gear, try sticking a Sansamp in front of it. You can get them used on the cheap even, and they can really fatten up your tone. IMO.
The others are right about not obsessing on the bass you are using though. I have used a P-bass, an EB-O, and a Jazz and was always able to get a nice fat reggae tone.
My thoughts exactly.
Though I don't doubt you can get a fat tone from the Epi, you might have trouble with getting enough clarity without a decent PA.
Technique wise, as others have said, after feel it's all about muting and getting those big notes to stand out by leaving enough space between them.
I recently saw Robbie Shakespeare live again, and I still couldn't get my head around how distinct every note was, even during his crazy fast fills and pumping Rockers style lines.
Re: tone, while I agree feel and note placement is paramount, there are very few styles of music where the bass is so prominent in the mix, and where the other instruments give it so much room. Its role is closer to a lead instrument in most reggae, defining the song while supporting it at the same time, and its audience is usually not only familiar with many basslines we play, but will probably be especially 'attuned' to it, too. so for once the hunt for a ranking tone will not only be appreciated by yourself but by your public. You don't only have to sound good, but you have to sound good LOUD!
Riddim come forward!
