Summing

Press the SUM button to switch between stereo and dual mono. 
Output features DMS™ which stands for Dual Mode Summing. 

Unique circuitry, designed by Goodwood Audio, that provides two 

types of summing, Stereo Sum and Split Sum. The default setting  

is Stereo Sum.

Stereo Sum

Use this mode when the last pedal in your signal chain is stereo. 

When the SUM button is out a true stereo signal is being sent to 

your amps. When the SUM button is in, the left and right signal 

being sent by your last pedal is combined to mono, and then split 

to both outputs – commonly referred to as dual mono. This is 

useful if you only have one amp at rehearsal or at home, but two 

amps live. When you only have one amp, press the SUM button in to 

preserve your stereo ping pong delays, and then press it again for 

when you have two amps. When you’re playing live with two amps 

and one dies, press the button in and the repeats of your ping pong 

delay will be combined to both outputs so it doesn’t matter which 

amp fails.

Split Sum

This mode is best suited to people who run a mono pedal board, 

but like using two amps. To change to this mode take the lid off the 

box and move the two dip switches from Stereo Sum to Split Sum. 

Connect your last pedal to the L in of Output and leave the push 

button out. This will create a dual mono signal. If you push the 

button in the L output will stay active, but the R output will have  

no signal.
