VOL – The Volume knob sets the overall output volume of the pedal. The Eras has quite a bit of volume
on tap, so the Volume knob will be helpful to find the sweet spot for interacting with the rest of your rig.
BLEND – The Blend knob allows you to blend between your fully clean and fully distorted signal. With
this control at minimum, the output is your original, fully clean input with no distortion. As you turn
the knob to the right, more distortion is added. At maximum, the output is the fully distorted signal
with no clean blended in. Blending the clean and distorted signals allows you to increase note clarity
as the clean and distorted channels run parallel to each other inside of the Eras. If you run a boost,
overdrive, or other distortion before the Eras you can create a unique mixture between the two using
the Blend control. Any gain added before the Eras input will affect both the internal clean and dirty
channels. The Blend knob is great for bassists as well.
GAIN – The Gain knob sets the amount of gain applied to your guitar signal passing through the
overdrive circuit.
BASS – The Bass control allows you to cut or boost low frequencies after the distortion circuit. This can
help tighten up the low-end or increase low-frequency emphasis. The low-frequency response of the
Eras is interactive with the gain control, so at higher gain, there is naturally more bass, while at lower
gain, there is less bass. The Bass knob helps to balance out the wide range of gain that the Eras offers.
Starting at noon, turn down to remove bass and turn up to add bass.
TREB – The Treble control allows you to increase treble to punch through a mix at high gain, or roll off
to smooth out low gain signals. Like the bass control, you may find that at higher gain, you will want
to add more treble, and at lower gain, you may want to roll the treble back. Starting at noon, turn
down to cut out highs and turn up to allow more highs.
MODE SWITCH – The Mode switch is a five-position
rotary switch. Each position offers a different
combination of internal gain and clipping styles
employed by the pedal. You can think of each
position as a different “flavor” of the pedal. Each
position is described in more detail below.
MODE SWITCH
I. Tight mode with a slight mid-cut, LED hard-
clipping, and internal volume compensation.
Fastest response, great for palm muting.
II. Tight mode with a slight mid-cut and silicon
hard clipping. Smooth with added compression.
III. Dual clipping mode with a slight mid-cut and
both silicon and LED hard-clipping. Rich & full with
added sustain.
IV. Rhythm mode with a deeper mid-cut, LED hard-
clipping, and internal volume compensation.
Scooped mids, tight response.
V. Rhythm mode with a deeper mid-cut and silicon
hard-clipping. Rhythmic, warm and full.
A new Era of distortion is here with the Eras Five-
State Distortion. Create mythical level riffs that’ll
leave everyone seeing red.
Eras is a no apologies, high-gain distortion that’s
ready to chug, shred, and palm mute with tight
response and multiple clipping options. Use the
Blend knob at max for a full distortion onslaught
or roll back the Blend knob to creatively stack and
mix other dirt pedals placed in front of Eras. Great
for bassists that want to blend in their dry signal
as well. However you set it, the Eras is ready to
deliver a diverse world of speaker ripping sounds.
Note: Since the Mode switch is changing the internal gain and clipping style, the other controls will
behave slightly differently as well. You will need to use the volume knob to adjust the overall output
up or down depending on which mode is selected.
