Amels Audio Launches With Osetra All-Tube Instrument DI

The newly launched Amels Audio has released Osetra, a direct-coupled all-tube instrument DI, as its debut product.

Audio designer Dave Amels’ new venture is an independent company making original hardware for musicians and recording studios. The Osetra DI is designed for use with electric guitar, bass, and pickup-equipped acoustic guitars, and comes first in an eye-grabbing, numbered 20-unit Founder's Tin Edition.

Osetra uses an original Class-A, transformerless circuit with no loop feedback. Its low-capacitance instrument input presents a 1 MΩ load, which helps preserve transients and contributes to a responsive playing feel. Measured response runs from 4 Hz into the megahertz range, with the observed upper limit set by the receiving microphone preamp. The tube B+ supply comes from 48 V phantom power, and the included universal-input 12 VDC adapter powers the filament.

Each Founder's Tin Edition unit is assembled at the bench and housed in a laser-cut caviar tin with sturgeon artwork. The Osetra product page (amelsaudio.com/osetra) hosts comparison videos and audio demos. These include level-matched bass and acoustic-guitar comparisons against familiar tube and FET DIs, plus standalone electric- and acoustic-guitar demos.

Amels Audio draws on founder Dave Amels' career in electronic musical instruments, mathematically modeled audio software, and analog recording equipment. Since the late 1980s, he has designed hardware and software for musicians and recording engineers, including at three companies he co-founded.

"Amels Audio gives me a place to invent and build the kinds of tools I want to use," said Amels. "They have to be technically serious, musically responsive, and useful in a working studio. Osetra is the first."

Osetra Founder's Tin Edition units 01–20 are available directly from Amels Audio for $425. Each comes with a universal-input 12 VDC filament adapter and a one-year parts-and-labor warranty. Initial sales are limited to the United States. For more information visit amelsaudio.com.
