"Tonebones don't sound like regular distortion pedals; they're smooth, professional... no rough edges. They respond like a quality amplifier. You hear all the nuances."

Features & Specifications

Built like a tank yet small enough to fit on a pedalboard, the Tonebone Hot British is the world’s most compact tube distortion. It is in fact a hybrid that combines the control of a triple-stage solid-state front end with the warmth and natural even harmonic generation of a 12AX7 tube. The tube is mounted on its side to keep the profile low for easy pedal action.

Power for the Hot British is provided by a external 15VDC supply and is regulated and filtered internally to eliminate hum and noise. To further reduce 'self noise', a unique ground plain circuit topology is employed, making the Tonebone Hot British one of the quietest pedals in its class.

Tonebone is also built tough—14-gauge steel construction reduces stress on the PC board and a baked enamel finish will keep your Tonebone looking great for years!



  Specifications
Circuit type:
Hybrid tube / proprietary circuit
Tube type 12AX7 vacuum tube
Input impedance:   1meg Ohm at input jack
Output impendence:
10K Ohm
MID BOOST
3-way switch:
Used to fatten up the sound for more cut and sustain during solos. Also, will fatten up the sound of single coil pickups
High:
Medium:
Bypass:
+12dB @ 620Hz
+6dB @ 390Hz
No boost
Drive control: Used in conjunction with the drive gain switch, drive is used to adjust the overall amount of gain to the overdrive circuit.
VOICING
3-way switch:
Allows the user to jump to chunky scooped rhythms in the NOTCH position or huge solos in the FAT position.
FAT:
bypass:
NOTCH:
Mid-boost - passive filter
Flat
Mid-cut - passive filter
Contour control: Used in conjunction with the VOICING selector switch, 'contour' dials-in the mid-center frequency with cut or boost with the switch in the NOTCH or FAT position.
TOP END
3-way switch
Switch sets the overall tonal character of the Classic to best match the amp and settings. Brighter amps are normally compensated with darker settings.
Bright:
Flat:
Dark:
Boosts +6dB @ 10kHz
No boost
Cuts -6dB @ 1.8kHz
HIGH & LOW EQ controls: Unity gain to +15dB
Low:
High:
+/- 14.5 db @ 100Hz
+/- 10 db @ 4.3kHz
LEVEL control: Used to balance the output level between the input drive without altering any of the tonal characteristics. Works like the master volume on an amplifier.
Footswitch: True bypass with green on/off status LED
Heavy-duty high-cycle switch
LED indicator:   Large 3mm OD ultra-bright status LED
Switching:
