GainOver – British-voiced overdrive [Black series]

• Out of stock

GainOver is a two-preset, British-voiced overdrive with switchable channels and independent Gain and Volume controls. The “Low Gain” section ranges from a quasi-clean boost to a creamy full dynamic crunch with clear attack, while the “High Gain” section maintains these properties while producing more drive saturation. The GainOver design is based on the PCN (Progressive Clipping Network) proprietary circuit, a complex analog net designed to obtain a dynamic and progressive approach to distortion, reproducing the incoming saturation of an EL84 Class-A final stage of a tube amplifier.

THE SMILIN’GHOST- Dynamic Percussion Tremolo

• Out of stock

Renato is frightened by the ectoplasm that suddenly emerges from the fireplace, but you must not be afraid: it is a good ghost with a nice flickering laugh. The Smilin’ Ghost is a Dynamic Tremolo Percussion, flagship of TEFI projects, developed after months of research and experimentation. It uses an optocoupler like in vintage amplifiers driven by our modern wide-range LFO (from 0.7Hz to 15Hz). The special proprietary circuit “TRFI”, totally analog, allows to control the activation of the modulation depending on the dynamics of the instrument’s execution: in this way it is possible to decide, with the energy impressed on the notes played, the activation or not effect. The two types of modulations are:

• Tremolo: gives a uniform modulation, driving the opto-isolator with a sine or square wave.
• Percussion: The envelope is a percussive type; using a lever-switch you can decide between fast and slow decay.

The LFO speed can also be controlled with an externally connectable expression pedal. The T.R.F.I control can also be activated with remote control.
