Reverb effects come in many shades, but Erica Synths sought to forge a desktop unit that merges fully fledged stereo sculpting with malleable musicality. Not surprisingly, the Latvian synth specialists found their answer with NightVerb. Housed in an elegant aluminum chassis, boasting eye-catching aesthetics and ergonomically satisfying tactility, 
NightVerb prioritizes the intersection of spatial and musical possibilities of reverb effects. Erica Synths deploys its custom-designed DSP engine, tapping the good folks at 112dB to develop an electrifying stereo reverb algorithm. 
Complete with true stereo I/O, MIDI in and thru ports, a footswitch jack, and a suite of detailed controls, Sweetwater’s sound designers find NightVerb to be an unbridled sandbox of multidimensional possibilities, spanning subterranean sonics and cavernous echoes to evocative swells and dynamic space-shaping snaps. Its 12 parameters can be controlled entirely via MIDI CC, with 2-way MIDI communication augmented by one of its most inspiring capabilities: a freeze function that features chromatic tuning and full MIDI playability. By focusing on the preservation of harmonic character, even the longest decays won’t fizzle out, allowing you to conjure musical magic as deep as the night.

Unique guitar synth & tracking pedal
The MINI-ARK is a monophonic tracking device. This means that it works very differently on different types of sounds. For example, a monophonic guitar line is going to achieve far different results than a super compressed drum track. Snazzy FX recommends that you first think about the source you are putting into the box, and then adjust accordingly.

Analogue modulation for any audio source
The Tracer City is in many ways very similar to what you might find on an old (or new) analog synthesizer. The main components of a synthesizer it has are filters, an oscillator (which can also be used as an LFO) and a Psuedo-Random LFO with lag. It also has an envelope follower (with up or down response) with lag, which works very well with drums, loops, and anything else which is very percussive. Like a synthesizer, the Tracer City allows its multi-mode Filter to be controlled by two external CV sources. You can also plug audio sources into these inputs (this creates Frequency Modulation of the Filter or FM) If you are familiar with modular synthesizers or analog synths, then the control names in many cases should be self-explanatory and you will simply need to get a hang of the layout and get used to the way that the modulators are routed to the filter.

Wow and Flutter

Bringing together the best of the digital and analogue worlds, the Zen Delay is a BPM-synced stereo delay line, combining extreme feedback ranges for dub and experimental lo-fi effects with a multi-mode 24 dB synth filter and valve overdrive.

Created and manufactured by Erica Synths, the unit is housed in a metal case with Erica Synths’ signature bakelite knobs and a valve circuit for extra analogue warmth. While sonically versatile, it is incredibly easy to use — each function has a physical knob that you can play around with without diving into manuals or scrolling through menus on a tiny screen.

Crafted in close collaboration with DJs and producers, the Zen Delay was uniquely developed with both live and studio use in mind and is suitable for many different performance situations, musical styles and instruments. While most delay devices are designed as ‘stomp boxes’ for guitarists, the device is equally powerful in the hands of electronic music producers, artists and DJs, adding a unique, warm and powerful sonic character to drum machines, loops, vocals, synths, samples or any other source. Even full tracks or a live stereo mix can be enhanced by the combination of analogue and digital circuitry, breathing new life into iPad performances and giving traditional digital synths and drum machines a huge kick.
