Plan-9

The Plan-9 Rams Head 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.

The present version (III) offers also a Muff / Bender toggle switch.

Mods:

We just performed mods that doesn´t affect the original tones. Beyond the toggle switch Bender/Muff, 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.
Muff / Bender toggle switch: alternates between the Rams Head tones and Supa Tone Bender style tones. Note that we say "Supa Tone Bender style tones". That´s because the Bender switch doesn't achieve, rigorously speaking, a perfect Supa Tone Bender sound, as the Plan-9 Rams Head transistors are BC239 and not the ones used in the vintage Supa Tone Bender. However the tones are quite similar.

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).
Fender witch hat knobs
Heavy duty metal box with electrostatic painting.
Detailed Operation Manual.
