Instructions

The 

Monarch Overdrive

 is an all 

discrete, FET-based dirt machine. 
It’s designed around the input stage 
of a vintage amp but configured to 
produce higher gains that sound 
very open and free of unnatural 
compression. The Monarch gives big 

bottom end with a snappy, bright top at all gain ranges with 
some careful tuning of the treble and bass controls. The 
treble and bass controls function as frequency boosters, 
not the traditional roll off filters in most overdrives. They are 
located in the preamp section and have a large impact on 
the over all tone, nature and distortion characteristics. If you 
are looking for an overdrive for big fat chords with excellent 
low end retention, this is it!

An EarthQuaker Devices original, the 

Monarch Overdrive 

has been out of production for some time, but now you can 
build your own!
