DemonFx Gravity Overdrive Clone Pedal

Gravity is our take on two all-time favorite overdrive circuits, the
Klon Centaur-style circuit and a TS10 circuit all in one enclosure!
A new dual overdrive specializing in mid push, Gravity will give you the
ability to cut through the mix in any situation.
The inspiration for this pedal lies in its name, Gravity and also by the
later live lead tones of John Mayer. In particular the outro solo tone in
his song "Gravity", and intro in his song "Belief", where he stacks these
two pedals to obtain that signature tone with a thick wall of mids.
The TS10 is often used as the main lead tone and the K-overdrive is
added as a second cascading gain stage, either as a pre drive into the
TS10, or as a post drive.

We have recreated the circuits in each pedal staying true to the original but added switching options for additional tone shaping. We have
kept both buffers that were used in the original designs in order to
replicate the exact interaction between the two circuits.
The Gravity overdrive is divided into a side A (left) and a side B (right),
separated by the order toggle switch in the middle which is used to
flip the internal order of the effects and hence the signal path from
guitar to amp.

Side A features the TS10 circuit with external knobs for DRIVE, TONE,
LEVEL and a two position toggle switch labeled LOWS. The lows switch
changes the bass response of the circuit.
The side B features the Klon Centaur-circuit with external knobs for
GAIN, TREBLE, OUTPUT and a two position toggle switch labeled
CLIPPING. The clipping switch toggles between a pair of germanium
or schottky clipping diodes.
Both sides can be used separately or stacked.
TRS split: Besides using the two sides of Gravity in serial mode,
either A->B or A<-B,
PLEASE NOTE THAT THE EXTERNAL ORDER TOGGLE SWITCH MUST
BE IN UP POSITION A <- B


Side A (left)
- Replica of the TS10 audio circuit including the three transistor buffer circuit.
- RC4558 Operational Amplifier
- External two position lows toggle switch for extended low frequency response
- Original Toshiba 1s1588 silicon diodes as in the original TS10 JP

Side B (Right)
- Replica of the Klon CENTAUR-circuit.
- External two position Clipping switch to choose between a pair of Germanium
- or a pair of Schottky clipping diodes.
- The germanium diodes we use are NOS original russian NOS D9B.
