Vintage pleasure

Not only does the MP566 look cool as hell, it is also a wonderful choice for a retro sound from the 50s and 60s. The circuit design is apparently inspired by the preamps that Bill Putnam Sr. built in his early years for the 610 console. While the original features two valves (one 12AX7 and one 6072), the MP566 comes with one small valve only to fit the size of a 500-series module. Nonetheless, if you are looking for a 'round’ overdrive sound without any harshness, even the small valve used in the MP566 can do good things to your signal. I absolutely love it on a shortscale bass with flatwound strings for a pretty authentic 60’s bass sound. It can also add sweet and creamy harmonics to large condenser mics. Overall, perhaps it’s not your no. 1 go-to preamp that you will use every day, but when you do, you will be glad to have this flavour in your toolbox.

Amazing API sound

I bought a couple of these MP512 some months ago. I use them for snare top/bottom. Simply amazing. The pad function is excellent to push the pre and "compress" with saturation. I'll buy more for sure.
