OVERVIEW

The Mix-Blender™ is in fact two pedals in one. On one hand it is a mini 2 X 1 mixer, on the other, it is an effects loop
manager. Following the block diagram below, two of Radial’s award wining Class-A buffers drive the inputs which are
then summed together to create the relative mix. The signal is then routed to the footswitch where it can feed your amp
or – when engaged – can activate the effects loop.

The Mixer

1

The Mix-Blender’s MIX section lets you combine any two instrument level sources together and set their relative volume
levels. You could for instance have a Gibson Les Paul™ with powerful humbuckers connected to input-1 and then a Fender
Stratocaster™ with lower output single coil pickups connected to input-2. By setting the levels for each, you can switch

between instruments without having to readjust the level on your amp.

2

The Effects Loop

A typical effects loop either turns on or off the effects pedal chain that is connected. In this case, the BLEND section lets
you blend in the desired amount of the ‘wet’ effect into the signal path without affecting the original ‘dry’ signal. This lets

you retain the original tone of your bass or clean electric guitar and mix in – for example - a touch of distortion or anging

to your sound while retaining the fundamental tone.
