The NUX line of mini pedals offers a line smartly engineered products that pack quality features at a great price. The NUX Edge delay combines emulations of three classic delay types: Phi Digital Delay, Roland Space Echo and the Boss Analog Delay. You can access the delays hands-free by holding down the footswitch, and there is even a smart tap tempo option. 

Small in space but not capability, the NUX Edge is an excellent way to add delay to your board.

In the words of NUX:

The Edge Delay Provides You With 3 Unique Delays, Each Including Acurate Control Over Its Sonic Character and Feel. Clear, Studio-Quality Digital Delays. Saturated and Fluctuating Sounds of Tape Delay Machines. Warm and Fuzzy Analog Style Repeats.

• ΦPhi Digital Delay is a digital delay with a golden ratio 2nd repeat head. It makes your guitar sounds more musical in nature. Easily tweak the knobs, setup the desired sub-division, engage the smart tap tempo, and you’re ready to go.
• Tape Echo is based on the legendary Space Echo machine. We digitally recreated the retro-feel of a real tape and capstan configuration. The Tape Echo emulates the high-frequency saturation and low-end decay of magnetic tape. It’s gently modulated for added richness and color. Tweak the time knob from max to min quickly, and you can get the infinity feedback.
• Analog Delay is based on the vintage BBD (Bucket Brigade Device) delay. It produces a very warm sound with natural treble decay. Very suitable for scorching ballad solos with romantic atmosphere. Our unique algorithm replicates the physical infinity oscillation feedback while you tweak the time knob from max to min quickly.

DELAY SUB-DIVISIONS WITH SMART TAP TEMPO. Set the Time knob parameter to your desired sub-division, then you can engage the smart tap tempo by pressing the footswitch twice to get a dynamic sub-division tap tempo delay.

Press the footswitch once to engage/disengage the effect. Press twice, to access Smart Tap Tempo. In the meantime, the delay time is related to tap tempo and current sub-division parameter. (The FS indicator will flash as current BPM.)
