MODE

The 3-way toggle switch selects the mix configuration

of the dry and wet signals:

chorus: (left position) combines a 50/50 mix

of dry and wet to achieve maximum depth

and the classic vibe effect

blend: (middle position) combines a 70/30

mix of dry and wet to reduce the depth for a

milder effect

vibrato: (right position) only the wet signal

for a classic, frequency-dependent, phase-

vibrato effect

SPEED

Controls the rate of the LFO sweep�

The 3-way toggle switch sets the center point

of the LFO for a range of vibe experiences:

low: (left position) the sweep is centered

around lower frequencies for a pulsing vibe

effect

mid: (middle position) the sweep is optimized

for a balanced vibe effect

high: (right position) the sweep is centered

around higher frequencies for a wide-

ranging vibe effect

INTENSITY

Adjusts the LFO sweep amplitude� At minimum,

the LFO amplitude is zero, resulting in a static

effect determined by the BIAS setting�

Controls the output level of the pedal, up to a

4dB boost at maximum�

Mono In - Mono Out: To connect UltraViolet in a mono signal chain, use

TS cables for both UltraViolet’s IN and OUT� Set the I/O Selector switch

to mono�

Mono In - Stereo Out: To feed a mono signal into UltraViolet, use a TS

cable to UltraViolet’s IN� Connect a TRS + dual TS cable to UltraViolet’s

OUT to route UltraViolet’s stereo signal to a stereo pedal� Set the I/O

Selector switch to mono stereo�

Stereo In - Stereo Out: To connect UltraViolet in a stereo signal chain,

use TRS + dual TS cables into both UltraViolet’s IN and OUT� Set the I/O

Selector switch to stereo�

*NOTE: Alternatively, you can use a TRS - TRS cable when connecting a pedal

with a TRS stereo input or output (such as connecting to the TRS stereo input of

a Strymon cloudburst stereo reverb)�

Tap Mode Switch Setup

Optionally, you can use your Strymon MiniSwitch or an external, non-

latching (momentary) type switch to access UltraViolet’s Tap mode� This

allows you to “tap” in a tempo to which UltraViolet’s LFO can sync�

The Strymon MiniSwitch includes an internal jumper switch that must

be changed from its factory FAV/BOOST Mode setting to work for the

UltraViolet Tap Mode momentary switch functionality� Follow these steps

to configure the MiniSwitch’s jumper switch and EXP/MIDI jack�

1 Unscrew the four screws on the bottom of the MiniSwitch chassis�

2 Once opened, locate the small jumper underneath the circuit board

and change it from the center and right pins (FAV/BOOST Mode) to the

center and left pins (TAP Mode)�
