SILENT TRUE BYPASS in the EXAR pedals
Most guitarists know that True Bypass switching is needed to prevent
tone sucking when an effect is not in use; but most True Bypass systems
create as many problems as they solve. The Exar Silent True Bypass
perfects the art of effect switching.
Standard True Bypass systems are based around the mechanical switch.
This is a simple and low cost method, but poor reliability, clicking and
popping during switching, low quality signal transfer can all be a
The Exar Silent True Bypass substitutes the unreliable mechanical
switch with a jointless magnetic switch, microprocessor and relay, which
is practically indestructible.
Clicking and popping during switching is eliminated using an innovative
microprocessor controlled circuit design. In the space of just a few
milliseconds, the signal is short-circuited, the micro-relay contacts
are switched, and then the signal is re-connected again. This process is
unnoticeable and provides you with noiseless switching of every single
Switching is done by a special micro-relay with 24 carat gold-plated contacts providing much better signal transfer. This micro-relay uses very little current and only while switching, so it has almost no effect on battery life.
All the benefits of standard True Bypass without any of the problems; the Exar Silent True Bypass sets the new standard.
