Check out this review of the Marcus Miller Preamp from the February 2009 issue of Bass Player!

SWR has partnered with Marcus Miller - arguably the most influential bassist of his generation – to create the ultimate tool for bassists. Or as Marcus calls it: “The missing link between your bass and a great sound!” Working closely with our SWR engineers, Marcus painstakingly customized the feature set of this preamp to accommodate his own distinctive array of tones, while taking into consideration the needs of other bassists of all styles. The result is simply one of the most versatile bass products ever developed.
