CONGRATULATIONS
on your purchase of Phaser, part of our ToneBug series of eect pedals that combine great-sounding T-Rex tone, premium retro design,
and aordable pricing.
Phaser is a classic phase shifter that will bring your sound to life by
adding dynamic, undulating colour to rhythm and lead parts. It’s got
all the controls you need and nothing you don’t – and it delivers the
incredible tubey vintage tone you expect from a T-Rex pedal.
Using Phaser couldn’t be easier. Just turn the page to get started.

READY, SET, PHASE!
Using your ToneBug Phaser
Insert a 9V alkaline battery or connect to a T-Rex Fuel Tank power
supply (not included).
Plug your guitar into the INPUT jack, and run a lead from the OUTPUT jack into your amp.
Use the RATE knob to set the speed of your modulation, and the
DEPTH knob to choose how “heavy” you want the eect to be.
Try switching between Modern and Vintage modes to get the tone
you’re looking for, and then set your overall output volume with the
LEVEL knob.
