## RP-1 Delay Reviews in United States

### ***** "IMHO- The Best Dual Digital Delay on IOS Period!"
I was looking and looking, already had BBD, already have Analog Delay, already had Tape delay, I couldn’t believe I already owned this Digital delay! So glad I did because, it truly is one of the best! IMHO, the best I found in IOS and universal AU as well. I will be using this in my pedalboard with ToneX plugin dual amp setup on my iPhone and analog drives pedalboard. 

I highly recommend this delay and supported by no other than one of the bet IOS developers!

### ***-- "Problems with iOS 14"
Please this app have problems with iOS 14. I can not save preset
-- lestercondee1989, 2020-09-30

### ***** "Deep Stereo Delay & Delay Modulation"
The Rotary slow panning preset sells this effect on its own - total spatial depth with a slight Doppler effect that’s unlike any other out there. There are undiscovered insanities in the app as well .. thinking the long dub delay effect. 
Considering it does every modulation delay effect from flanging to chorus and vibrato, with the ability to create multiple instances of multiple effects through the AU feature, it’s well worth it. 

For tape delay with all of the noise, flutter, and wow and ability to manually stop the reels in real-time, check out RE-1.

### **--- "Crashes"
This app worked great on my iPhone 6s but mysteriously crashes after launching just fine if I plug my headphones into my iPhone 8, despite having the most recent upgrades.
-- Funfunfunfun!12343213423411, 2019-01-23

### *---- "does not work"
really - does not work !!!!
-- Nileheats, 2018-08-10

### ***** "Has become my favorite delay."
I use this on my guitars mostly. It has this beautiful stompbox kind of simplicity that I like but all the sound of a studio rack unit. 
It works very well on acoustic guitars using the modulated delays

Recommended by me.
-- Gitarzz, 2018-03-28

### ***** "Works great with new update"
Thanks. Sounds great.
-- Gambilito, 2017-06-11

### *---- "Crashes constantly in AUM"
Worthless. Every time I leave AUM and then switch back this plugin crashes.
-- MusixMonkey, 2017-02-06

### ***** "Sick! Stop Snoring!!!"
This app has to be one of the best I've heard in the app world. Might be the best period! I have no idea why I am the first to review this musical FX app. All y'all electro's out there, get your little 6 dollars up (there aren't even any hidden cost) and grab! Or go sample the sounds on their website yourself! 5"stintnys" all day long!
-- MacBezzy, 2016-07-20

### ***** "Beautiful"
This may not only be the best delay out there, but also the best effect app period. It is that versatile- delay, flange, phase, chorus, tremolo...
Beautifully designed and works like a dream.
-- Ben Efitofadoubt, 2016-06-12
