The C451 B Small-Diaphragm Condenser Microphone from AKG is well suited to record drums, percussions, acoustic guitars and strings in the studio and in live situations. It is engineered to approximate the sound of its predecessor, the C451 EB + CK1, but with its redesigned hand-crafted fixed capsule (which eliminates the mechanical problems associated with the original modular design), and its low-noise preamp electronics, this microphone delivers accurate transients for a bright and detailed sound.

AKG C451B Overview

The C451 B Small-Diaphragm Condenser Microphone from AKG is well suited to record drums, percussions, acoustic guitars and strings in the studio and in live situations. It is engineered to approximate the sound of its predecessor, the C451 EB + CK1, but with its redesigned hand-crafted fixed capsule (which eliminates the mechanical problems associated with the original modular design), and its low-noise preamp electronics, this microphone delivers accurate transients for a bright and detailed sound.

AKG C451B Reviews

Great Microphone

By Chris

I have always been a big fan of the AKG small capsule condenser microphones. Sounds amazing for drum overheads or acoustic guitar placed near the nut.

Excellent Choice

I have a project studio and record primarily acoustic instruments (Guitar, piano, various stringed instruments, hand percussion and vocals etc) Already own a set of Neumann KM 184's and an AKG C214 Large Diaphragm but have always had a fondness for the AKG small diaphragm sound ever since I started out years ago with a Vienna made C1000 (which I still have and love). I wanted another small diaphragm option and the 451's deliver big time. To be totally non technical I would describe the AKG's sound as open and airy especially on fingerstyle acoustic guitar. I tell people think of the old Windham Hill guitar sound. (yes I know they used Neumann's too). You will not go wrong with this mic if you play acoustic music.
