Purple Audio BIZ MK

I just wanted to drop you a line to let you know how much I like the Biz module I purchased from you. Over the past two weeks I have been tracking a bunch of electric guitar (Les Paul and Marshall JCM-800) and we went through a pretty thorough comparison of quite a few different flavors of pre amp that I have in my set up. We put an AEA R-92 ribbon in front of an old Marshall 4X12 cab and went to town. The candidates were: API 312, API 512C, API 512A, Biz, OSA MP-L3, OSA MP-L, Chandler LTD-1, a pre from an E-Series SSL, and an old Ampex 351. All were great sounding in their own way, but both the player and I continually came back to the Biz and ended up using it for a majority of the tracks with some Chandler (for the 1073-esque flavor) and the 512C thrown in to add some different flavor. I found the Biz module to be big and thick – but not tubby. Aggressive – but not too edgy, and overall a very complimentary pre for the amp/guitar/mic combo we were using. I knew a product like this from you guys would be very good, but I have to say that the Biz is a stellar pre amp. I also intend to spread the word to my other 500-Series brothers
