I use an AD2022, which is basically 2 M5's... I don't believe there is a better basic clean preamp anywhere, short of a Martech...It is also a badass bass and
acoustic guitar DI box. Paired with a bright, clean mic, such as a C414, it is stunning on acoustic guitar. When used with a pair of KM184's as overheads, it almost makes the other drum mics pointless. On vocals, you either have to get the color from the mic, or just have a badass singer. I consider the Avalon to be the heart of my studio.-Richie
