How the TONE BONE benefits your amps voice:

The tone of a CLASS A operated guitar amp is well known from the legendary VOX AC30. Tone gets more alive, the amp responds more directly and musically. It instantly improves sustain, thickens tone and is adding a three-dimensional character with decent compression and smooth harmonic distortion when driven to the limit. The overall loudness will be reduced as the Class A as the EL84 tubes provides less output volume. So you can crank up your amp all the way and achieve best sonically performance at reasonable volume ( 8 ヨ 30 Watt, depending on your amp and the TONE BONE version you use).

PENTODE or TRIODE version?
The TONE BONEル is available as PENTODE and TRIODE version. Both versions basically provide the same benefits. The PENTODE supports the main tonal character of your amp while the TRIODE will clearly make it more linear but will compress and saturate much earlier. The TRIODE makes it sound much smoother and will drop down power output of to about 8 watts when using 2 TONE BONE converters.

Both versions will provide you outrageous sustain and let you achieve more even distortion sound when cranked up and still give you perfect control with playing dynamics.

PLUG & PLAY or How to install
Switch off your amp, pull out the power tubes (6L6GC, 5881, EL34 or 6V6GT) and plug in TONE BONE converters including their EL84 tubes, switch amp on. Done!

Dimension: the ToneBone is without pins 12cm high (5cm adaptor + 7cm EL84). 1cm air gap between the top of the EL84 and Cabinet is required for mounting and air flow.

The TONE BONE is total self-adjusting. No adjustments, no modifications! As you do not adjust the bias you might switch back to the original power tubes at any time you want. Real PLUG & PLAY!

The overall power output depends on your amp and the version of TONE BONE converters you use:
Pentode: 7 - 9 Watt per converter, 14 -18 Watt per pair
Triode: 4 - 5 Watt per converter, 8 -10 Watt per pair

A 100-Watt amp with 4 6L6GC, 5881 or EL34 would saturate usually at 100W RMS power output. With TONE BONE converters it saturates at:

TONE BONE Pentode: with 4 converters about 32 Watt, with 2 about 16 Watt
TONE BONE Triode: with 4 converters about 18 Watt, with 2 about 9 Watt
  1. Blackstar ht60 combo Review by Stevenholt

    I bought these to lower the output which they do nicely to about half making the master volume more useable . Basically it turns the amp into an AC30 tone and volume wise but with great flexibility . Unfortunately for me the loss of the Blackstar tone made me change back . The already superb cleans became true vox like chimes. The amp became an AC30 on steroids is my summary, but it turned out to be not what I wanted after all. I will keep them though in case I join a diff band or get another amp . (Posted on 16/05/2012)
