- Drive the input of your signal to achieve unique saturation
- Optimal tone at all times thanks to drag load correction
DISC Radial Firefly Tube Direct Box Overview
Inject some vintage mojo into your recordings with the Radial Firefly Tube Direct Box. You'll receive an abundance of warmth and character thanks to the Firefly's Class-A design which drives a 12AX7 tube.
The Firefly is equipped with A and B instrument inputs, each with their own independent level controls. The box enables seamless instrument switching, whilst the unique Drag Control load correction allows you to adjust the load on magnetic pickups so that it feels as though it's connected to a tube amp. This control can be bypassed to increase the impedance of the Firefly's inputs.
A Thru output allows you to connect to your on-stage amplifier, and offers a choice of pre- or post-tube configuration. On top of all of this, the Firefly also features a 1/4'' TRS insert effects loop for interfacing with pedals and rack FX, resulting in an incredibly versatile and powerful direct box with phenomenal tone.

- Class-A front end drives 12AX7 tube stage
- Two inputs with seperate gain and remote switching
- Drag control load correction for optimal tone
- Variable high-pass filter to eliminate resonance
- A/B trim controls for matching the gain between the two instruments
- Selectable active input for fast instrument changes with indication LED
- Variable low-cut filter for rolling off low-frequency resonance
- Drag control can be used to retain the natural feel of the instrument by adjusting the load for passive pickups
- Level control for the balanced XLR output
- 12AX7 tube drive circuit for warmth and character
- The harder the Firefly is driven, the better it sounds
- Balanced output is transformer-isolated to eliminate hum and buzz caused by ground loops
- I-Beam reinforced enclosure makes it impossible to torque the PCB and eliminates cold solder joints
- Military-spec PCB with full ground plane for noise-free performance, and double-sided for durability
- Locking 5-pin XLR power connection with +/-16V that is internally stepped up to 48V
- High-Z always-on tuner output
- High-Z thru-put for a stage amp, configurable for pre or post-tube and insert
- 180° polarity switch inverts the signal polarity
- Thru/Pre switch assigns the tube and effects insert loop to the stage amp thru output
- Buffered effects insert loop uses a TRS 1/4'' cable to interface pedal and rack effects
- Aux Isolate/Direct sets the 1/4'' aux out to direct or transformer-isolated to eliminate ground loop noise
- Optional rackmount kit can be obtained that allows one or two Fireflies to be rackmounted in a single 19'' space (rackmount kit not included, must be purchased seperately)
