Tube Killer


AMP IN A BOX / Fuzz / High gain overdrive

The Tube Killer was born through the search for that characteristic sound produced in some pre-70s tube amplifiers while being pushed to achieve saturated sounds. With the tubes almost melting and the speaker about to explode, some incredible sounds were produced on these amps. Featuring its two gain stages —Fuzz and Gain— added to the Tone and Voice controls, this pedal delivers that specific response. Now abide and revisit those saturated sounds from the golden age.

Tube Killer Inspira Fx

Main features

Much of the character of the Tube Killer is obtained through the use of JFET transistors, with which can achieve a very similar response, both operational and harmonic, to that of vacuum tubes.

The pedal of 1000 voices

The first gain stage corresponds to a BJT transistor, which by adding a bit of its saturation to that of the saturation of the first stage of the JFET preamp, it achieves a more roaring, warm sound with greater sustain. The control that handles that stage is fuzz.

The second stage of gain corresponds to the saturation of the second stage of the JFET preamp, it is a sound that resembles more with an overdrive, although it reaches insane saturated levels. The gain control works like the volume in a tube amp, the more it increases, not only increases saturation but also the overall sound has a lot more presence.

Preamp feel

Without an exaggerated sustain in most of the travel, eliminating part of the upper end of the frequency range, and added to the structure of the saturation, we find the perfect mix between fuzz and overdrive. A pedal with its own identity.
