Vacuum Tube Large Diaphragm Condenser
We started designing the P-28 by looking at two of the very best early tube SDC microphones.
The P-28 recreates the low-end performance of the 1955 AKG C 28, while bringing the high-end qualities of the 1954 Neumann KM 54. Employing a sub-miniature triode tube similar the KM 54s, brings a smooth quiet warmth. Inspired by the C 28, we used an easily removable head grill protecting a swappable capsule. The provided cardioid capsule can be exchanged for other polar patterns capsules. The P-28 meets the modern demand for an ultra-quiet noise floor while delivering the warmth and character of these revered vintage microphones. This is accomplished with a FET amplifier stage prior to the tube amplifier stage. This hybrid FET-tube combination delivers just what we were looking for; the quiet and reliability of a FET with the warmth and character of a tube! At the output stage we of course use a custom transformer to provide reliable balanced signal.
This unique FET-tube SCD is one of the best sounding SCD microphones made in any time period. Put it up on drum overheads, on any stringed instrument, or in a Decca Tree with an orchestra to find out why engineers say this is one of the best microphones of our entire line.

he Peluso P-28 excels on most string instruments, especially acoustic guitar, alone or in a stereo X/Y set up. Speaking as a percussionist, I love the full, open dimensionality of the P-28 on djembe, cajón, congas, klong-yaw (google it), doumbek, and tabla. It also excels in pairs for drum overhead duties, offering a full, rich capture of the kit with gentle cymbal control. As a spaced pair on drum overheads, the P-28 provides a large diaphragm condenser sound, but with the focus that a small diaphragm mic offers, so much so that I quite enjoyed a single P-28 as a mono drum overhead.

Next I set it up for some acoustic guitar work with my Taylors. I was actually very much amazed. I actually heard things I hadn't heard before while playing and recording my guitars, including the most annoying moving of my lips. That aside, this mic sounds wonderful on my guitars. I wish I had two to use. Full-bodied tone and no boom, even on the dreadnought. Nice, clear, bright highs. But smooth, not brittle.
