Make Your Own Point Contact Transistor

Beyond the power variant, it sometimes seems as though we rarely encounter a discrete transistor these days, such has been the advance of integrated electronics. But they have a rich history, going…

THRYALLIS, Germanium guitar overdrive/boost, dual gain. One of the most versatile ODs out there.
- Improves the sound of the drives that come after it.
- Wonderfully pushes an amp that is set on the edge of breakup
- It can work as a tuneable treble booster that can be stacked nicely with other overdrives.
- It can be subtle at low gain but also aggressive at max gain.
- Offers a vintage attitude.

MEKKA fuzz (Germanium version) is a result of an idea my friend 'Orestis' had for a custom fuzz pedal a while ago. With some experimentation and some changes & additions the final circuit for MEKKA fuzz was born.

The circuit draws elements from ‘70s Soviet fuzz circuits and from contemporary fuzzes as well and at its core a couple of Soviet Germanium transistors are responsible for the gnarly sounds it can produce.

The addition of a two band Baxandall EQ same as the one used in the Orange OR120 amplifier is what adds to the pedal extra versatility, offering the ability to create countless more tonal results.
The EQ can be engaged or completely bypassed with a toggle switch.

Controls:
- Stability: Keeping it fully clockwise produces the most predictable results. In any other position it will most likely start producing oscillations which are audible when you’re not hitting the strings of your instrument.
- Gain: Turning it clockwise increases the intensity of the fuzz.
- Compress: Generally it changes the way the circuit responds to your picking producing a more compressed result and also changing the attack. In combination with a low Stability setting in can create some interesting results. It also changes the tone and softness of the fuzz.
- Gate: Turning it clockwise results in a more “gated” sound and it also reduces any squeals and buzzing noises
- Vol: Output level.
--------------------
- Voltage Required: DC 9 Volt
- Polarity: center negative
- Max Current draw: 20mA

The MEKKA fuzz in this specific form is a limited series pedal and very few pieces will be produced since we’re not fans of the Germanium hype.

Transistor Radio Repair, More Complex Than It Seems

The humble transistor radio is one of those consumer devices that stubbornly refuses to go away, but it’s fair to say that it’s not the mover and shaker in the world of electronics it m…

THRYALLIS, Germanium guitar overdrive/boost to push your amp or stack with other pedals.

- Improves the sound of the drives that come after it.
- Wonderfully pushes an amp that is set on the edge of breakup
- It can work as a tuneable treble booster that can be stacked nicely
with other overdrives.
- It can be subtle at low gain but also aggressive at max gain.
- Offers a vintage attitude.


The toggle switch offers you 3 different sound possibilities:
- Middle position (N): Normal state. Transistor only.
- Bottom position (d): Adds a diode-clipping stage.
- Top position (L): Adds a high-cut filter.

- Voltage Required: DC 9 Volt
- Polarity: Negative tip
- Max Current draw: 2mA
- True Bypass
