Connections
We recommend that this pedal be placed after any overdrive. If you use the
overdrive channel of your amplifier, this pedal should be placed in the
effects loop for best results.
The Power Jack accepts a standard (5.5 mm OD x 2.1 mm ID) center-
negative pedal power adapter (not included). The power adapter must be
between 9V and 12V and capable of supplying 80mA or more.
The Input Jack (right side) accepts input directly from your instrument,
amplifier effects loop output, or other effects pedals via a standard 1/4" (6.35
mm) phone connector.
For line-level (+4 dBu) input, we recommend keeping the Mix knob below
60% and using a 12V power adapter.
The Output Jack (left side) supplies output to another effects pedal, an
amplifier, or effects loop return via a standard 1/4" (6.35 mm) phone
connector. The buffered output is capable of driving long cables. If plugging
into the input of an amp, you should use the low impedance (Lo-Z) input if
available.
The Mix Knob controls the mix between the dry signal and effect:
Full counter-clockwise is 100% dry
Full clockwise is 100% effect, typically used with a parallel effects loop
Approximately 3 o'clock is an even mix: half dry/half wet
The Depth Knob controls the length of the reverb tail, or in other words, the
size of the acoustic space.
The Shim Knob controls the amount of shimmer in the effect. With this knob
fully counter-clockwise, there is no shimmer: the effect is reverb only.
The Foot Switch bypasses the effect. The LED lights when the effect is
active. Bypassing the effect does not lower power consumption, because it
does not turn off power to the pedal.
Bypassing (buffered bypass)
With the buffered-bypass version of the Seraphim Shimmer, the signal is
always buffered whether the LED is on or off. The two bypass modes are:
Buffered Trails—allows the reverb to trail off naturally after the pedal is
bypassed
Buffered Normal—cuts off the reverb tail immediately when the pedal is
bypassed
Bypassing (true bypass)
With the true bypass version of the Seraphim Shimmer, the bypassed signal
may be selected to be buffered or true bypass. The two bypass modes are:
Buffered Trails—allows the reverb to trail off naturally after the pedal is
bypassed
True Bypass without trails—cuts off the reverb tail immediately when the
pedal is bypassed
Changing the Bypass Mode
When the pedal powers on, the LED will blink to indicate the bypass mode:

2
Normal / True-Bypass
To change the bypass mode, unplug the pedal or turn off the power supply.
Hold down the footswitch while re-applying power to the pedal. The pedal
will switch to the next mode, and the number of blinks per second indicates
the current mode.

Switching Between Shimmer and Reverb-Only
Using the footswitch, you may select between reverb-only and shimmer
reverb:
A short press (less than ½ second) enables or bypasses the effect—both
reverb and shimmer.
A long press (greater than ½ second) enables or bypasses the shimmer
only, whether or not the effect is currently bypassed.
The LED indicates the current mode as follows:
LED
Effect
Bypass
constant off
reverb
bypassed
constant on
reverb
enabled
short pulse
shimmer
bypassed
long pulse
shimmer
enabled
When the shimmer effect is disabled (reverb-only mode), the Shim knob is
also disabled.
