Features & Specifications


Build like a tank… Compact to fit on a pedalboard, the Tonebone Classic is the world’s most compact tube distortion. It is in fact a hybrid that combines the control of a dual-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 pedal profile down for easy pedal action and is powered by an external 15VDC supply. Power is internally regulated and filtered to eliminate noise. To further reduce self-noise a unique ground plane circuit topology is employed making the Tonebone classic the quietest pedal 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
Drive gain
3-way switch:
 Used in conjunction with the drive gain control. Drive switch selects the gain range of the overdrive circuit.
Low:
Med:
High:		 Normal mode (+0dB Nominal)
Medium distortion (+9dB)
High distortion (+20dB)
Drive control: Used in conjunction with the drive gain switch, drive is used to adjust the overall amount of gain to the overdrive circuit.
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
FILTER control: Balances the ratio of high frequencies between amplifier and Classic distortion to compensate for overly bright amplifiers.
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:
Opto-coupler assisted, 5msec Rise time
Construction:
14 gauge steel, baked enamel finish
Size:
7"w x 4 1/4"d x 2"h (174 x 108 x 51mm)
Weight:
2.15lb (1kg)
