FETTO Jr. 70 – Great Ol’ Distortion
Great Ol’ Distortion @ Little Package!
The FETTO Jr. 70 is based on an early FETTO design from 2006 (FETTO 11.1) and delivers a distinct ’70s-style overdrive – warm, harmonically rich, and smooth. It is designed to enhance high-quality valve amps while preserving clarity, dynamics, and note definition.
When paired with Himmelstrutz amplifiers such as the King Cobra, GOAT AC30s, Gnome, or Space Gnome, it integrates seamlessly – enhancing response and feel rather than masking it.
The result is a responsive, expressive overdrive that follows your playing with precision.
Note: For similar tones with extended control and integrated Class A boost, see FETTO Nord 70+.
FETTO Jr. 70 Background
Born in 2004 with FETTO 9.0. Refined in FETTO Nord 70.
FETTO Jr. 70 keeps the core – the feel, the bite, the harmonic push – but strips away the extras. From edge-of-breakup to full singing sustain. Touch sensitive. Amp-like. 70’s in the fingers.
Discrete Class A (PACO) buffer onboard – switchable between True Bypass and Buffer mode. Small box. Serious attitude.

FETTO Jr. 70 LAYOUT / Controls
| IN / OUT | |
| Input | Input impedance: approx. 1 MΩ |
| Output | Output impedance: approx. 10 kΩ |
| Push Switch | |
| GIMME | Mechanical switching (true bypass or buffer*) for the OVERDRIVE circuit. * Slide switch below output jack selects True Bypass or Discrete JFET Class-A buffer. |
| LED Indicator | |
| Status LED | LED turns ON/OFF depending on switch state. LED colour is the colour of the day. |
| Power | |
| DC Input | 9–18 V DC, very low current draw (no internal battery). Optional AC adapter: 9–18 V DC, center-pin negative (BOSS-style, regulated). |
| Potentiometers | |
| Drive | Classic Himmelstrutz amp-like overdrive; light → medium → heavier textures (never Metal). |
| Tone | Passive high-frequency control. |
| Volume | Output level (as loud as you’ll ever need). |
| Internals * | |
| Internal configuration is used for fine-tuning and voicing, and may involve switches, jumpers and/or trimmers. * Details may vary depending on version and serial number. | |
| Dimensions & Weight | |
| Size | 93 × 38.5 × 47 mm (L/W/H) |
| Weight | Approx. 160 g (0.35 lbs) |
| Colour / Finish | |
