Sender Spike Releases FREE Echobox D7 Delay VST Plugin


Sender Spike has released Echobox D7, a freeware delay effect in VST plugin format for Windows-based digital audio workstations.

Echobox D7 is based on a now-discontinued Japanese digital delay pedal. The modeled delay pedal was intended as a simulation of a classic tape echo effect. The developer didn’t provide more precise information about what hardware gear was modeled, so we can only guess. What’s most important, though, is that Echobox D7 oozes with character, delivering a crunchy analog-style tape delay sound.

The interface is relatively simple and optimized for a fast workflow. The user can adjust the delay time, feedback amount, and the volume of the delayed signal. The delay time knob can be set to a specific range (there are three value ranges to choose from) or run in sync with the host application. Both dotted and triplet time values are supported. The plugin also features a bypass switch. This is a “true” bypass switch, meaning that it clears the echo signal stored in the buffer.

Unfortunately, there is no way to shape the tone of the delayed signal. The only adjustments can be made to the delay time and the volume of the echo signal on the output. That said, Echobox D7 is handy as a simple tape delay effect that can be used to deliver that classic tape delay sound in a matter of seconds.

Echobox D7 can be downloaded for free from Sender Spike’s website. You don’t need to register for a user account nor activate the software. Both 32-bit and 64-bit host applications are supported. You should also check out Sender Spike’s excellent Signal Noise SN03-G Tape Recorder plugin.

  1. Sender Spike are Crazy dudes who thicken up my DAW sound for free, i‘m really in suspense how it compares with TheEcho in Propellerheads Reason as tape echo Dickicht toil. I will report how it compares in the next days ;)

  2. This thing is super cute, everything that guy does actually so be sure to lurk around his website. It is worth noting that since this article, the plugin was updated with some well deserved and welcomed stereo shenanigans, along with a much better system for Dry and Wet levels as discrete knobs. 7 stars out of 5. Keep ’em coming, Spike!

    Thanks for spreading the word. As for what hardware is modeled, I’ll leave you a clue – “Tone-Lok” ;)

    That clue gets me nowhere, but this delay is amazing. It really has that old school vibe down. I’m comparing it to my echoboy, and arturia delays presets and it just seems to beat them out character wise. Thanks a ton!
