I'm wondering why more people don't recommend or use the Markbass Super Booster? I just bought one recently and have to say it's great. I've used the Sansamp Bass Driver and the MXR M-80, and in my opinion this DI is far better. You can get a great fat tone by dialing in the VPF a little and you can really warm things up by dialing VLE, not to mention tame an OD going to the board. Another great thing is I can boost my signal a little if need be and the booster is not so hot that it's unusable. Is the biggest drawback the 12v power or are there other reasons it's not mentioned more often?
