 First made in 1962, it took until 1965 to catch on when Keith used one on Satisfaction – and the world of guitar tone was changed forever. The FUzz tone used three germanium transistors to amplify and clip the guitar’s signal creating fuzz, glorious fuzz…"

Maestra Fuzz Tone

Trem Spring

This pedal has been built with the JTM45 circuit in mind, replacing the tubes with Mosfets (unlike other pedals, using Opamps to emulate the tube sound)

Two standalone channels:
A = Overdive Plexi-Tone
B = Clean Boost

With a toggle switch, you can choose between: A on B or B on A. It's like having two pedals in one.

Super Plexi V

Edge Echo baby – The pedal simulates the sounds of old echoes. This time, to obtain the desired sound we literally "put through the wringer" all our original vintage "delay effects", including the Italian Farfisa AS2006, a very rare tape echo to find,
and the known Binson Echorec.

Old echoes have always been considered a warm form of delay and very suitable for guitar players.
Our Echo achieves similar results using a specially designed modern and reliable circuitry with super balanced sound that's not too crisp but not lo-fi either.

Edge Echo Baby

The 4558 is an Overdrive built around the famous OP-AMP 4558,
And it's our Vision on the classic TS808.
All super selected components with nos tantalum capacitors and original  diodes.
