The Sending Firmware version 2 will be available on November 19, 2024!

Sending is an analog delay that melds the archaic voice of bucket brigade devices with a fully modern toolbox of digital control. It embraces the character and idiosyncrasies of the medium while delivering high quality sound and performance-friendly features worthy of the modern musician.

Using two MN3005 BBDs and comprehensive analog processing techniques, Sending can delay a sound up to a full second without clock noise, and it can be pushed to even longer times for compelling sonic degradation. At the input is a discrete preamplifier capable of subtle enhancement or warm saturation that melds perfectly with the delay line. A dual-mode feedback filter shapes the repeats into deep pulses or dub-style bright echoes. Its flexible LFO engine can modulate the delay time to create gentle movement or musical chaos. Conducting this analog ensemble is a 32-bit, 100MHz processor granting deep user control, preset functionality, and MIDI access to every parameter.

Sending is our love letter to the antiquated yet enduring technology of analog delay. As you explore its many shades of interplay between past and future, we hope you find it as immersive as we do.

Controls

Each knob has a primary and secondary function. Access secondary functions by pressing Shift once. Press again to return the panel to normal.

Time: delay time from <5ms to 1 second

Div: tempo divisions

Color: adjusts preamp gain while keeping level consistent

Trim: adjust volume up/down by 6dB

Mix: wet/dry blend

Mix Mode: Sets Mix knob as a crossfader between wet/dry or as a delay level control only

Feedback: sets the number of repeats, from one repeat to self-oscillation

Swell time: adjusts speed of feedback swell when Tap is held

Filter: cut lows or highs in the delay line

Rate: LFO rate

Chaos: LFO randomization

Depth: LFO intensity

Shape: Set LFO waveform

Preset Select Buttons (I, II, III): long press to save a preset, short press to recall

Engage Footswitch: turn effect on/off. Long press to change the bypass mode.

Tap Footswitch: tap four times to set the delay time as a running average. Hold to enter Feedback Swell mode.

• A unique discrete preamplifier for subtle enhancement or full-range saturation that is automatically balanced for optimal output levels at all settings.

• Trails bypass mode that allows the preamp to be used as an always-on drive.

• Dual-mode Filter control that changes the tone of the delay repeats.

• Advanced analog filtering for low noise and high bandwidth on the delay line.

• Comprehensive digital control of every function using a powerful 32-bit processor system that seamlessly integrates with the analog signal path.

• Tap tempo with subdivisions and a hold mode for feedback swells.

• Delay time LFO engine with sine, square, and triangle waves plus a unique Chaos function that modulates the delay time using a truly random Lorenz attractor.

• Insert loop to apply external effects to delay repeats within the feedback path.

• Save and recall up to 32 presets: 3 via the front panel, the rest via MIDI.

• CV/Expression input that can be mapped to one or multiple controls.

• TRS MIDI input for control changes, preset selection, and clocking.

• Web-enabled firmware updates via the MIDI jack.

Specs:

Bypass switching: Electronic bypass with buffered or Trails modes. Trails mode passes signal through the preamplifier.

Input impedance @ 1kHz: 1MΩ

Output impedance @ 1kHz: <1KΩ

Power: 9VDC, 2.1mm center negative barrel. Current draw is 350-380mA depending on the Time setting.

We recommend a regulated, isolated power supply rated for 400 mA minimum. The DC input is protected against reverse polarity and over-voltage up to 24V. Our pedals do not accept batteries.

All Electronic Audio Experiments pedals come with a warranty tied to the original owner.

Version 2 (July 2023)

Complete circuit overhaul. Consider this the new starting point.

Version 1 (Summer 2018)

Original release; only 55 units built.

In many ways, this is a completely different product. For info please visit the legacy product page.

V2 (November 2024) Note: new units are shipped with v2 beginning with Serial Number #508. For a fully detailed changelog, refer to the Technical Manual.

Revamped LFO engine w/ improved tapering, more natural V/Oct pitch movement, continuously variable Shape, clock sync mode, and arpeggio easter egg mode

Modulation Matrix

CV clocking mode

Major updates to Swell mode: adjustable feedback, increased range of swell time, momentary activation in Trails mode, new Hold mode

Improved clock accuracy

Quality of life improvements including reduced LED brightness, parameter resets, and more

Bug fixes:

Reduced feedback in trails mode to eliminate bleed

Fixed PC message behavior for preset loads. Now, sending a message twice reloads the preset instead of exiting to the live panel state.

Fixed a bug that prevents the bypass state from not saving correctly

Fixed a bug that resulted in occasional missed button presses.

FAQs

What type of power supply does the Electronic Audio Experiments Sending V2 require?

The Electronic Audio Experiments Sending V2 requires a standard 9V DC power supply, center-negative. It does not support battery operation.

Can the Sending V2 delay pedal be used with a bass guitar?

Yes, the Sending V2 is versatile and can be used with both electric and bass guitars, providing rich delay effects suitable for a variety of musical styles.

Does the Sending V2 offer tap tempo functionality?

The Electronic Audio Experiments Sending V2 does not include tap tempo functionality. It is designed to offer high-quality delay tones with manual control over delay time.

What are the main tonal characteristics of the Sending V2 delay pedal?

The Sending V2 is known for its warm, analog-inspired delay tones, making it ideal for adding depth and texture to your sound. It excels in creating ambient soundscapes and lush repeats.
