Seraphim Shimmer v2 User Guide

Thank you for purchasing our product. We really mean it. We hope to earn your trust by delivering a quality product that inspires you to make great music.

Neunaber products are designed and manufactured in Orange, California USA.

Connections

We recommend that this pedal be placed at the end of your chain, before or after another reverb. Also, shimmer will have more sibilance if placed after a speaker simulator rather than before. If you are using the overdrive channel of your amplifier, this effect should be placed in the effects loop for best results.

Power

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 9 V and 12 V and capable of supplying 100 mA or more.

Input

The input jack (top right) accepts input directly from your instrument, amplifier effects loop output, or other effect pedals via a standard 1/4” (6.35 mm) phone connector.

Output

The output jack (top left) supplies output to another effect 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.

Footswitch

The Engage switch selects between engaged and bypassed. 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.

Press and hold the footswitch for 1 second to switch between reverb only and reverb with Shimmer. Release when the LED illuminates red.

Primary Controls

Mix

The Mix knob controls the mix between the dry signal and reverb:

  • Full counter-clockwise is 100% dry
  • Full clockwise is 100% reverb
  • Approximately 3 o’clock is an even mix: half dry/half wet

Depth

The Depth knob controls the length of the reverb tail; or in other words, the size of the acoustic space.

Shimmer

The Shimmer 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 Shimmer knob is inactive in reverb-only mode.

Alternate Controls

These controls are accessed by holding down the Engage footswitch while turning the knob.

Effect

The effect control switches between the popular original shimmer algorithm and the new W3T shimmer algorithm (which is the same as the algorithm on the Immerse Mk II).

Trails

The bypassed signal may be selected to have trails or not. When Trails is on, the effect signal trails off naturally after the pedal is bypassed. When off, the effect cuts off immediately when the pedal is bypassed. 

The LED will momentarily change color to indicate which bypass mode is selected.
