Congratulations!
You are now the proud owner of the compact but powerful Crate MX20RC amplifier. Two
versatile channels – one crystal clear and the other with our patented “Flex-Wave” distortion –
combined with reverb and a three-band EQ and a switchable Chorus offer you more flexibility
and performance than any amp in its class. Our “Flex Wave” circuitry uses sequential cascad-
ing gains to deliver distortion which is rich in harmonics and is touch sensitive. A special damp-
ing circuit simulates the “current source” type of output of a tube amp, giving you solid state reli-
ability combined with classic tube sounds.
Like all Crate products, your MX20RC is designed by musicians, and built using only the
best components. Extensive testing confirms that this amplifier is the absolute best it can be.
In order to get the most out of your new amplifier, we strongly urge you to read the infor-
mation contained in this manual before you begin playing.
And
thank you for choosing
