I have noticed that most Clarus owners use some kind of preamp to augment thier amp. I'm curious to see what everyone ells uses, whether it be an onboard or outboard preamp. I have a Clarus and use it along with an MXR M-80 Bass Driver preamp into a Music Man Audiophile 2x10. I love this combo! Punchy as hell, does a decent low B reproduction and sounds great in a live band. So, what do you use?
