Germanium Boost. Triangle Muff. Full EQ control.

Mt. Hood


The Mt. Hood is our collaboration with the Get Offset Podcast. Emily and Andrew are really great folks and their podcast is a lot of fun. We started talking about doing a pretty basic fuzz and got a little carried away. The Mt. Hood has its humble beginnings as the first ever series of Big Muff, the Triangle version. We ditched the tone control for a passive 3 band eq tone stack, added a presence control after the last gain stage for more tone shaping, put a footswitchable Germanium boost with gain and tone controls, and a diode switch to add an extra order of magnitude of tonal options. 


The Germanium boost is on the right side switch and its controls are indicated by the clear knobs. It utilizes a NOS transistor had selected and measured for this circuit. Spruce Effects is known for utilizing this type of circuit as a stand alone channel as well as a building block for other fuzz and distortion circuits. On its own, it can create loads of subtle tone shaping options or push your amp into serious overdrive. The tone control allows you to manipulate the frequency that is boosted at your guitars input, which is useful running the boost on its on as well as into the fuzz side. 


The Fuzz side is a version of the famous Triangle Big Muff pie and is tuned especially for this pedal. There aren't a lot of 3-band muffs out there, so we wanted to create something familiar, but also drastically different and interesting. The tone stack has controls for treble, bass, and middle and are all highly interactive in a series of low and high pass filters. The presence control tames some of the harshness and gives you a final control on what the fuzz sounds like. 


The toggle switch in between the two footswitches lets you select between traditional diodes or LEDs in one of the clipping amplifiers. The down position is louder, less compressed, and gives more tight distortion sounds. 


Stacking both channels opens up a huge new front of sounds, going from more subtle all the way to more rage. Check out the demo and try for yourself. 

  • Switchcraft Jacks
  • High quality true-bypass stomp switches
  • Enclosure printed and drilled in the USA
  • Hand wired and assembled in California
  • NOS Germanium transistor in boost circuit
  • High-quality Wima/Kemet/Nichicon capacitors and Xicon resistors
  • Standard negative ground power--this pedal plays nicely with others!


We always recommend isolated power supplies. If you daisy chain effects on one supply (ours can handle that despite being Germanium PNP powered), you may inject noise, ripple, ground loop hum, etc. This effect requires 9v, center negative power. In other words, the industry standard power supply.  



  • Top-mounted jacks, input on right, output on left
  • True-bypass stomp switch is on/off, indicated by LEDs

Fuzz Side

  • "Volume" controls the amount of output volume 
  • "Fuzz" controls the amount of fuzz or "distortion"
  • "Presence" controls the amount of presence
  • "Bass" controls amount of lows cut
  • "Middle" controls the amount of mids cut
  • Treble controls the amount of highs cut

Boost Side

  • Gain controls the amount of gain 
  • Tone controls the input volume (ccw is treble and thin, cw is bass and fat)

All controls are incredibly interactive so experiment!
