The Tonebone Classic is a very flexible distortion pedal. It has three drive settings and a variable drive control, you can dial in everything from dirt to drastic and everywhere in between. The Classic is exceptionally dynamic and transparent and as such, is extremely adept at retaining your playing style and signature.

Drive and Level Controls:
The Tonebone Classic design follows the way a guitar amplifier works whereby the input DRIVE is akin to the input channel volume, while the LEVEL control acts more like a master volume control. As such, the DRIVE control provides overall input gain to the distortion circuit. This works in conjunction with the 3-position DRIVE switch that controls low, mid or high distortion range settings. At low settings, the Classic creates lighter rock & roll tones like the sounds you would hear from Keith Richards or the cleaner side of Hendrix. In the mid-distortion range, Stevie Ray Vaughan and Eric Clapton type tones come alive. At the higher distortion settings, Eddie Van Halen to Eric Johnson type solo tones can be created while big chunky rhythm tones from Boston to ZZ Top to Deep Purple are also easily attained.

Equalization and Tonal Structure:
The Tonebone Classic employs active post-distortion equalization for maximum flexibility. Tone shaping is performed with three controls and two switches thus allowing the guitarist to dial in the type of tonal structure that may be desired. HIGH and LOW equalization are extremely active providing up to 15dB of gain control. These work in conjunction with the TOP-END and MID-BOOST controls. Overall shaping begins with the TOP-END control with choice of Dark, Normal or Bright settings which are used to compensate for the tonal characteristics of the amplifier. The FILTER control overlaps the high-end with a subtle roll-off to further compensate for overly bright amplifiers. The MID-BOOST switch is used to fatten-up single coil pick-ups or to add 'meat' to the tone for additional cut during soloing. The Classic's mid-range frequencies have been carefully selected to work with popular amplifiers like Twins and Marshalls. These settings are extremely effective at compensating for 'clean' oriented channels on classic tube amplifiers.

Features

HIGH & LOW controls:
Post distortion active tone controls that boost or cut from 12 o'clock position
Low: +/- 14.5 db @ 100Hz
High: +/- 10 db @ 4.3kHz

FILTER control:
Balances the ratio of high frequencies between amplifier and Classic distortion to compensate for overly bright amplifiers.

DRIVE control:
Used in conjunction with the drive gain switch, drive is used to adjust the overall amount of gain to the overdrive circuit.

TOP END 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: Boosts +6dB @ 10kHz
Flat: No boost
Dark: Cuts -6dB @ 1.8kHz

MID BOOST switch:
Used to fatten up the sound for more cut and sustain during solos. Also, will fatten up the sound of single coil pick-ups
High: Boosts +12dB @ 620Hz
Medium: Boosts +12dB @ 620Hz
Bypass: No Boost

DRIVE switch:
Used in conjunction with the drive gain control. Drive switch selects the gain range of the overdrive circuit.
Low: Normal mode (+0dB Nominal)
Mid: Medium distortion (+6dB)
High: High distortion (+12dB)

Tube:
Standard 12AX7 vacuum tube inside is used in distortion stage to accentuate upper harmonics and warmth.
