Description
The Radial Firefly is a studio-quality direct box that combines the clarity and detail of an active DI with a tube drive circuit that provides vintage warmth and pleasing harmonics to any instrument.
- 12AX7 tube drive and class-A front end
- Dual inputs with separate gain & remote switching
- Drag control load correction for optimal tone
- Variable output connects directly to a PA
Fatten up your DI tracks
The Firefly’s drive circuit utilizes a 12AX7 vacuum tube, which is the most popular tube made today and can be found in nearly all guitar amplifier designs. This helps provide the character and feel of a vintage device, while still maintaining low distortion and noise profiles common to modern pro audio equipment. The Firefly excels when used on instruments that sound too clinical or one dimensional when recorded directly, adding punch and warmth to bass or guitar tracks both on stage and in the recording studio.
When viewing specifications, one has to differentiate between products that are designed to provide accuracy versus those designed to color and enthrall. The Firefly falls into the second category. Therefore the specifications that are normally used to qualify ‘accuracy’ have been omitted leaving those that are still relevant such as noise. One must also consider that tubes are inherently noisy compared with solid-state devices, so even here, the specs may seem less than ideal. But tubes bring a sonic character that excites. With the Firefly… one must really listen to appreciate.
