This pedal uses a sub miniature tube called 6112 also called pencil tube, these tubes are much smaller than the normal pre-amp tubes, more stable and last longer. These tubes are also used in various audio devices such as headphones and microphones. The 6112 tube was chosen because of the relatively high amplification factor 70. An ecc83 has a factor of 100 and an ecc81 factor of 80. The 6112 booster is not only appreciated for its boost capabilities but mainly for its sound properties. To save this, the pedal is often used on unity gain (un-amplified), often at the end of the effect chain, and is always on with most guitarists.
You can make all sounds of your pedals ‘bigger’, deeper and more harmonious in combination with the 6112. Delays sound much wider and deeper, your reverberation increases in color, distortions and fuzzes sound fuller and suddenly the 6112 tube just like an overdriven amplifier. . With the contour button you can fine tune the sound. It’s like your guitar sound goes from 2D to 3D.
Try out the 6112 before and after your pedals to find the ideal application for your guitar and playing style.
In combination with a distortion pedal, the 6112 works as an extra gain stage and with the contour knob you can subtly adjust your sound and adjust it to taste.
