Simble Twimble - owner’s manual
Thank you for purchasing the
Simble Twimble by Mad Professor.
The Twimble is a combination of the Simble
Overdrive and the Simble Predrive. Both of the
drives have been tailored slightly in order to
achieve an even more organic tonal result. As you
turn the Contour fully clockwise, you will notice the
overdrive section now features enhanced clarity
with a sparkling top end. The Predrive section has
additional sweet compression. This results in a
pedal with a more 3-dimensional tonal feel and it
is even more easy to transition between clean and
overdriven guitar tones using your guitar volume
control. In addition, you will notice more warm
sustain to ease playing.
Naturally, both drives sound excellent on their own,
on both singlecoils and humbuckers. And when
activated together they really make you ow.
The Mad Professor Twimble pedal allows you to be
the foundation of the tone. With the Twimble pedal,
your picking attack, your guitar and the pickups
you have chosen will retain their character, keeping
your valuable original sonic footprint intact.
THE SI MBLE OVERDRIVE SECTION:
When you rst plug in, please set the pedal as
follows:
• LeveL:
• Sen Sitivity:
• accent:
• contour:
At these settings, switching the pedal on/off
should not alter your tone. Your volume might
change depending how powerful the pickups
on your guitar are. Set the Level to match the
bypassed signal. Now you have a transparent
tone from where you can begin working on your
own tone.
Turn the Sen Sitivity CW to add more distortion and the LEVEL to set the output.
The ACCENT knob adjusts how much the pick
attack is accentuated at the pedal input. This control can also be used to brighten dark pickups.
Fully CCW there is no effect. CONTOUR adjusts
the tone of the output signal, turning it CCW softens the output for a jazzy tone, darker harmonics
and a better match for really bright ampliers.

• Sen Sitivity: Amount of distortion and
compression
• LeveL: Output level
• accent: Pick attack and brightness
• contour: Brightness of the output
(darker when you adjust CCW)
THE SI MBLE PRED RIVE SECTION:
Simble Predrive is not just a preamp, it is a
preamp/booster/compressor/upper harmonic
enhancer.

This dynamic preamp is designed for guitar and
other stringed instruments and should be placed
as the rst pedal after the guitar.
Simble Predrive boosts the signal, compresses
it without a slow attack time and adds musical
harmonic overtones.
This musical tonal combination is totally adjustable with your picking attack and guitar volume
control. The picking articulation also shines
through high gain tones.The amount of boost
depends on the level of the input signal and the
position selected on the HOT/COOL-selector.
The maximum boost is approximately +10db, with
an average boost of +6db. The Predriver also
smoothens out the most prominent transients.
The Simble Predrive’s special circuitry uses low
noise transistors with high input impedance (over
2 MOhms) making it possible to boost even piezo
pickups without loss of tone.
An output impedance of 50 MOhm allows it to be
used in front of fuzz pedals.
The power consumption is very low. By removing
the input jack when not in use, the pedal can run
on a single 9V battery for a few years.
