3D Model
This is an updated version of the V2
Stomp Box Adapter. It can be used as an
external input amplifier, a way to use effects
pedals with synthesizer signal levels, or as a
way to use synthesizer modules with
instruments such as electric guitars.
A little on how it works:
Modular synthesizers generally use
much higher signal levels than are used in
effects pedals, so directly connection the two
will create two problems. First, the excessive
signal will cause the input of the effects
pedal to overload/distort. Second, the output
from effects pedal is too weak to drive
synthesizer modules without some
amplification. To compensate for these
problems, the signal from the synthesizer must
be dropped to a fraction of what it was, while
the output of the effects pedal must be
amplified by the same amount to restore it to
a level suitable for the synthesizer.
The default CGS360 build uses a ratio
of 20 as this encompases the signal levels of
many synths. If you know for certain that the
ratio is too great, the ratio can be reduced
to reduce the amplification of any effects
pedal noise. For example, if an effects pedal
works on a 1V p-p signal, and a synthesizer
has a maximum output of 5V p-p, a ratio of 5
would be adequate. Refer to the Build Guide for
details.
Any of the sections can alterantely
be used as a simple External Input Amplifier
to allow external instruments such as a guitar
to be connected to your synth. In this
application you would omit the [SEND] circuit
of the relevant section.
