Everest II Stereo Reverb-Delay

$
$
The Everest II is a set of 12 reverb & delay combinations which can cover all the typical use cases for those effects (and can go way beyond those if needed). The pedal has individual controls for the delay and reverb sections, global stereo width control, and a "Hold" function. The Everest II can add beautiful echoes and reflections to your sound regardless of the instrument you play. Additionally, all the pedal's functions can be controlled via MIDI.
NB! The info on this page is based on firmware version 2.0.

The firmware v2.0 can be installed onto any Everest II pedal (starting with s/n 001), thus giving you access to all the functions described on this page. If your pedal has the older-style print, you can find a cheat sheet with the new functions' layout in the Downloads section.

Everest II: Key Features

  • 12 combinations of reverb and delay.
  • Independent controls for reverb and delay along with the option to use either effect in separation.

Connections

LEFT IN is a monophonic signal input. In a mono signal chain, use this input exclusively.

Controls

The Everest II has multi-function controls: each knob and switch can have several purposes. Primary functions are printed in bold. Secondary functions accessed by holding down the TAP / ALT footswitch are printed on the pedal with a border (and printed here in italics). The ones which can be accessed by holding down the ON / HOLD footswitch are underlined. In this text, each function is marked by the same principle.

Tweaking a secondary control function has no effect on the primary control function value, and vice versa. The primary and secondary functions are independent from each other, but only the latest one you've tweaked will have a physical representation (because they are controlled by the same knob or switch).
Primary Parameters (Direct Access)
The REVERB knob controls reverb volume in the wet signal. Turn this knob fully CCW to disengage the reverb.
Secondary Parameters (ON / HOLD)
HOLD + MODE selects among the B, R and M banks.
Please see the Banks & Patches section for details.
Secondary Parameters (TAP / ALT)
The RV.TONE knob controls the LPF at the reverb section's output. Turn this knob fully CCW to cut most of the high frequencies and get the darkest reverb tone. Turn it fully CW for the brightest reverb sound.
Press and hold ON+TAP for 3 seconds to save the current parameter values to the Favorite preset.

Bypass and Indication

The dry signal path is fully analog throughout the whole pedal. No latency or distortion is applied to the dry signal.
Due to the Everest II's active bypass, there is no audible clicking, and three independent global modes are available (selectable by the BEAT switch while holding down the ON/HOLD footswitch):
  • UP: "No tails" mode. The effect is only heard when the pedal is engaged in the signal chain and turns off immediately when the ON footswitch is pressed.
  • CENTER: "Tails" mode. After you have switched the pedal off via the ON footswitch, it keeps playing back delay repeats and reverb reflections but the incoming signal is no longer processed.
  • DOWN: "Kill Dry with tails" mode. The dry signal is completely removed from the output. Just like the previous mode, this one only engages the input when you press the ON footswitch. The active fragment is played till the end, so that the sound doesn't get cut off abruptly. This mode is highly recommended for Wet-Dry-Wet processing or external wet/dry mixing setups.
The bypass mode is displayed upon selection and upon power-up. The LED above the ON/HOLD footswitch flashes five times in one of the following colors:
  • Red: "No tails" mode.
  • Blue: "Tails" mode.
  • White: "Kill Dry with tails" mode.
The ON/HOLD LED has five functions:
  • On/off indication. If the pedal is bypassed (disengaged from the signal chain), the LED doesn't light up.
  • Active bank indication. Upon power-up, the LED displays the selected bank: Blue, Red, Magenta or Cyan.
  • Hold Mode status indication. When the ON/HOLD footswitch is held down, the LED flashes in various colors.
  • "Favorite" status indication. When the Favorite preset is recalled, the ON/HOLD LED glows green. If the pedal is bypassed but the Favorite preset is recalled, the LED flashes briefly to indicate that the Favorite preset will be active when the pedal is turned on.
  • Bypass mode indication upon selection or power-up.

Connection Options

LEFT IN is the main mono input. If you are using the pedal with a mono signal source, use this input exclusively. Connect the signal source to the LEFT IN input, then connect the LEFT OUT output to the signal receiver.

When in mono mode, the STEREO knob changes its functions. It now slightly changes reverb tone and affects the delay depending on the selected delay mode:
  • Stereo and Reverse: the STEREO knob introduces up to 30 ms of drift in delay time between the left and right channels;
  • Ping Pong: in the 7:00-12:00 range, the knob affects the volume (accent) of the second repeat. When set anywhere in the 12:00-5:00 range, the knob doubles the delay time for all repeats beyond the first one (max delay time in this mode is 2 seconds).
If you connect a signal source to LEFT IN and a signal receiver to RIGHT OUT, you'll essentially get the exact same setting except for Ping Pong mode. In the 7:00-12:00 range, the STEREO knob will control the volume (accent) of the first repeat. In the 12:00-5:00 range, the first repeat will be absent and delay time will be doubled (up to 2 seconds max). This option will suit you if you're looking for delay times over 1 second and/or need accented repeats. Using the RIGHT IN input in MONO mode is not recommended.

Stereo Setup

The pedal has two internal channel setups for the delay section: independent channels (Stereo, Reverse) or summed channels (Ping Pong). Reverb always processes the two channels independently.

Use the DL.TYPE switch to select the channel setup and the STEREO knob to control stereo width.

The STEREO knob affects the delay and reverb sections simultaneously, resulting in the most organic stereo image. It provides complex control over channel crosstalk and micro delays (for wide stereo and Haas effect). This way, a single knob allows you to place the wet signal in the center or push it to the sides, leaving the center for the dry signal. To visualize the knob's ranges in various modes, please refer to the image.


The 7:00-12:00 range controls channel crosstalk in reverb and delay:
  • 7:00 — 100% crosstalk; effects are summed to mono regardless of the initial settings at the input.
  • 12:00 — 0% crosstalk; the left and right channels are processed independently.
The 7:00-12:00 range controls channel crosstalk in reverb and delay:
  • 7:00 — 100% crosstalk; effects are summed to mono regardless of the initial settings at the input.
  • 12:00 — 0% crosstalk; the left and right channels are processed independently.
The STEREO knob also controls stereo image width for reverb and stereo delay. Unlike crosstalk, this parameter is controlled by the full range of the knob.

Splitting the ranges of the STEREO knob allows for independent left and right channel processing in case of series processing or double processing.

When using the delay in Ping Pong mode, the STEREO knob only affects channel crosstalk in the 7:00-12:00 range, while the 12:00-5:00 range has no effect on stereo image width. Set the knob to 12:00 for maximum width of Ping Pong delay.

Setting the Delay Time

Use the DL.TIME knob or TAP footswitch to set delay time in quarter notes, which can then be turned into triplets or dotted 8ths via the BEAT switch. The longest delay time (and also the longest tap interval) is 1 second. The TAP footswitch and the DL.TIME knob have the exact same effect on delay time. Delay time is determined by the control that has been used last.

The TAP LED displays the set tempo (in quarter notes by default). When the tempo is set via the TAP footswitch, the tempo change is not applied instantly; however, the next delay repeat will be played at the new tempo. This eliminates artifacts caused by delay time shifts; at the same time, it allows you to change delay time on the fly and achieve glitchy effects with the DL.REGEN knob set high. In turn, the DL.TIME knob changes delay time instantly by default, resulting in classic delay artifacts.

The DL.TIME knob has a "blind spot": the first 5% of its range have no effect on delay time. This allows you to set the knob fully CCW and only use delay filters and modulation without the actual repeats. This way, you can achieve mild chorus/flanger processing or high-pass filtering (depending on the selected mode).

Time indication mode, DL.TIME knob operation mode, and subdivisions are all accessible via the config file.

Banks & Patches

The 12 patches of the Everest II are organized into 4 banks, each holding 3 patches.

Use the MODE switch to select a patch from the bank.

To select the B, R or M bank, press and hold the ON/HOLD footswitch, then set the BANK switch to the desired position:
  • UP: B (Blue Bank). The ON/HOLD LED glows blue.
  • Center: R (Red Bank). The ON/HOLD LED glows red.
  • Down: M (Magenta Bank). The ON/HOLD LED glows magenta.
After that, release the ON/HOLD footswitch and select a patch via the MODE switch.

To select bank C (Cyan Bank), press and hold the TAP/ALT footswitch, then set the BANK switch to any position. The ON/HOLD LED will light up in cyan, indicating that the Cyan Bank has been selected. After this, you can release the TAP/ALT footswitch and select a patch via the MODE switch.

The config file provides access to another way of selecting patches.
Read more on the Everest II Support Page.

The ON/HOLD LED glows blue.
Set the MODE switch to the desired position:
  • Up: Sunshine. A sunny, snowy and frosty morning right atop the Everest. The delay and reverb in this mode are so bright and cold they will send shivers down your spine!
  • Center: Eclipse. Modulated delay repeats and solemn reverb reflections make for a perfect soundscape of the Himalayas at dusk.
  • Down: Moonshine. The initial delay repeats and reverb reflections are accompanied by octave sounds for a weird, otherworldly effect.

Hold Mode (Infinite Sustain)

Press and hold the ON/HOLD footswitch for more than 0.3 seconds to simulate turning the DL.REGEN and RV.DECAY knobs to the max. In this mode, reverbs become infinite or very long (2–5 minutes), delays go into maximum feedback, and the LED starts flashing in various colors. Release the ON/HOLD footswitch to let DL.REGEN and RV.DECAY go back to their knobs' settings.

Hold Mode is designed for gradual sound build-up and slow transition into self-oscillation and saturation. The speed of the build-up depends on the selected mode and overall brightness settings.

In Hold Mode, patches with resonant filters in the delay section go into self-oscillation faster than the rest. This can sometimes be used to generate sound even with no input signal present.

Favorite Preset

To store the current settings into the Favorite preset, press and hold the TAP/ALT and ON/HOLD footswitches simultaneously for 3 seconds. The preset will be recorded into the pedal's internal memory, and the ON/HOLD LED will light up in green.

To recall or exit the Favorite preset, briefly press the ON/HOLD footswitch twice. If the ON/HOLD LED is glowing green, the Favorite preset is active. If the Favorite preset has been recalled but the pedal is bypassed, the ON/HOLD LED lights up briefly: this provides visual feedback regarding the settings which the pedal will employ when engaged. When the Favorite preset is active, the ON/HOLD LED periodically displays the bank which contains the saved algorithm.

When the Favorite preset is active, controls on the pedal have no effect until you turn/switch them. If you exit the altered Favorite preset without saving, the changes you've made won't be recalled the next time you activate the Favorite preset.

The Favorite preset can use the global delay time setting as long as that function has been activated via the config file.

You can turn off the Favorite function or remap it to an external footswitch through the config file. Read more about Favorite preset settings on the Everest II Support Page.

External Parameter Control

The CTRL input allows you to set up external control over the pedal's parameters. It has several operation modes:
  • MIDI (Type A) control over all parameters. This mode is selected by default.
  • Passive controller (normally open momentary button). The controller mirrors the functionality of the TAP/ALT footswitch or recalls the Favorite preset.
  • S-trigger. "Short circuit trigger", analog trigger/gate with the same polarity as the pedal's. This is the recommended trigger type. This mode works equally well with active and passive controllers plugged into the CTRL input. Two operation options are available:
    • The TAP/ALT footswitch retains its functions even when a clock signal source is connected to the pedal.
    • The TAP/ALT footswitch has no effect on delay time and can only be used to access secondary functions.
  • V-trigger. "Voltage trigger"/"positive trigger", analog trigger/gate with polarity opposite to the pedal's. Use this trigger type if you have no S-trigger source. If no external signal is coming into the CTRL input, the TAP/ALT LED will light up and some of the pedal's functions will be inactive. Those functions become active as soon as a clock signal has been connected. Two operation options are available:
    • The TAP/ALT footswitch retains its functions even when a clock signal source is connected to the pedal.
    • The TAP/ALT footswitch has no effect on delay time and can only be used to access secondary functions.
To connect a MIDI source to the Everest II, use a 6.3mm TRS (stereo) Type A cable.The MIDI channel is set in the config file. In MIDI control mode, delay time is set by MIDI Clock, the DL.TIME knob, or the ALT/TAP footswitch (whichever has been used last).

Passive controllers and analog triggers take over the ALT/TAP footswitch and set delay time. The Everest II is designed for quarter-note clocking (1PPQN) with 0.005-1s intervals between two consecutive signals. The lowest clock rate is 60 BPM. The stable clock rate range is 60-300 BPM. Clock precision depends on the stability of control signals.

CTRL input operation mode is selected via the config file. Please see the Everest II Support Page for more details.
