SPECIAL FEATURES 

AUDIO BUFFER 

Using long cables or many e

ects may degrade the guitar signal, causing it to lose clarity and definition. 

The audio bu

er is used to “strengthen” the guitar signal and preserve sound quality. The e

ect may 

vary from subtle to significant, depending on the length and quality of cables and type of e

ects used in 

your rig. 

The main input goes through an input bu

er before being sent to the switching matrix. The bu

er can be 

turned on or o

 by pressing the Bu

er button on the front panel. If the bu

er LED is green, the bu

er is 

on. If it’s yellow, the bu

er is o

. The bu

er can be programmed to turn on or o

 for each preset, and can 

be set to automatically turn o

 when certain loops are active, using 

Fuzz Mode

BUILT-IN TUNER 

The Mini E

ect Gizmo X has an integrated tuner that’s available when used with one of our Mastermind 

controllers (GT, LT and PBC). The Mini E

ect Gizmo X does the actual calculations, and sends the tuner 

data to the Mastermind to be displayed on its main display.  

The Mastermind needs to be running firmware 4.6.1 or later to support this feature. Also, the Mini E

ect 

Gizmo X’s MIDI input needs to be connected directly to the Mastermind’s MIDI output using a 5-pin 
active MIDI cable (A 5-pin MIDI cable with all 5 pins wired) or 7-pin MIDI cable. There can’t be any other 
MIDI devices in between the MEGX and Mastermind. Also, bidirectional MIDI needs to be turned on in 
the Mastermind’s MIDI settings (applies only to the Mastermind GT and Mastermind PBC/10) 

FUNCTION SWITCHES 

The Mini E

ect Gizmo X has the ability to control footswitchable features on many amps. This could be 

channel switching, reverb, tremolo, etc - just about anything that’s controlled by a 1/4-inch footswitch 
jack. The 

FN SW

 jack is used for this purpose. You can use a standard 1/4-inch mono (TS) cable, a TRS 

1/4-inch cable or an insert cable to connect to these jacks: 

Mono 1/4-inch cable 

- a mono or TS cable allows you to control one function on an amp using Function 

Switch 1. This type of connection is typically used with amps that have single button footswitches. 

TRS 1/4 inch cable

 - a stereo or TRS cable allows you to control two functions on an amp that has a two 

button footswitch. 

Insert cable

 - an insert cable is a 1/4-inch cable that has a TRS (stereo) connector on one end and two 

1/4-inch TS (mono) connectors on the other. This allows you to connect to two 1/4-inch TS switching jacks 
on the same amp. Some amps - most notably Mesa/Boogies - have multiple switching jacks that would 
work with this arrangement. 

Please note!

 Don’t connect the two mono plugs of an insert cable to two 

di

erent amps or two di

erent pedals - in many cases, this could cause a ground loop or worse electrical 

problems.
