Plan-9

The Plan-9 Rams Head Muffin Si recreates one of the first Big Muff Pi editions, known as the "Violet Rams Head". It´s know for its superior sound when compared to the current US and Russian versions.

Mods:

We just performed mods that doesn´t affect the original tones. The Plan-9 Rams Head has protection against polarity inversion, RF blocking, noise filter, led and true bypass.

Transistors:

As the original BMP, the Plan-9 Rams Head is powered by four matched BC239 silicon transistors and four matched 1N914 silicon diodes.

Controls:

Sustain: controls the fuzz and sustain intensity
Volume: limits the output signal intensity
Tone: controls the amount of high, medium and bass tones.

Features:

True bypass 3PDT footswitch.
External power supply jack and internal 9V battery snap.
Hand wired circuit with off board mounting of jacks, switches and pots.
Four selected BC239 transistors.
4 matched 1N914 diodes.
Circuit protection against battery polarity inversion, radio interference and on/off noise
Constanta potentiometers, big and tough, vintage style made in Brazil (eventually we can use CTS or Alpha).
