Himmelstrutz FETTO AX7

Preamp Punch with FETTO Feel

FETTO AX7 is built around a true high-voltage 12AX7/ECC83 valve stage. It keeps the FETTO idea of dynamic amp push, but moves it toward a more open, immediate and voltage-driven preamp behaviour.

It is still a pedal, still made to live in front of the amplifier. The voice is bright, fast and punchy, with clear attack and a strong upper-mid push.

FETTO AX7 (Axe Seven) feels especially at home in the British landscape – where chime, bite, growl and amplifier response are part of the language.

Drive Side

The valve drive adds body, gain and harmonic push before the amp.

Boost Side

More level, more punch and a harder hit into the amplifier input.

Bias Switch

400V gives punch and headroom. 200V overdrives earlier. The third mode keeps 200V but cuts some top-end.

Your Amp, Hit Harder

Still your guitar, still your amp – just pushed harder, brighter and more alive. Any FETTO keeps the player in charge and lets the amplifier do the talking.

FETTO AX7 is delivered with an ECC83 valve, because that is where it started – in Great Britain. Why this babe was later baptised FETTO AX7 is another question.

A 12AX7 valve will also work, and for less gain with more brilliance, an ECC81/12AT7 can also be used.

Want a more raw AX7 flavour? The valve can also be swapped for DIME-X – a high-voltage transistor alternative with a little more gain and a wilder edge.
