This looks to be a good unit, unfortunately there is NO way to access any of the promised functionality of this unit! It would sure be nice if they supported Windows! They wont allow me to pick ZERO STARS, so I will give it an undeserved 1*

Not Windows compatible!

I was led to believe that this unit was Windows compatible, NOT! Unfortunately, without buying an Android or Apple device, most of this units functionality is NOT available! So much for Windows compatibility. I gave it 3 stars, because the unit most likely sounds good, just not functional!

Beyond disappointed

There’s no denying that this pedal sounds amazing. But here’s a cautionary tale. I experienced Bluetooth connectivity issues with the Del-Verb, so I performed UA’s recommended firmware update, which caused my Del-Verb to stop functioning completely. It won’t boot or pass any sound. I’ve updated firmware on pedals from many major manufacturers and have never experienced anything like this. But that’s not the worst part. Since I did not purchase the pedal directly from an official UA dealer, I am excluded from UA’s one-year warranty… again, this is on a pedal that is less than a year old, has been kept in outstanding condition, and was ruined by UA’s own firmware update. The sole option provided to me by UA is to try a local UA distributor in my country to see if they can perform repairs, for which I will bear 100% of the costs (including shipping), and could ultimately cost as much or more than buying a second Del-Verb brand new.

To say I am disappointed and shocked by this experience is an understatement. It sucks especially because I loved this pedal’s sounds and form factor. Really let down - this was my first experience with UA and it will definitely be my last.

Great Sound - some bugs

Best sounding delay/reverb combination pedal by far!

Would be great to be able to store presets - eg with long pressing the buttons or via the app.

Makes sometimes loud pop sounds when switching effect types.

Would be great to have full parameter access to all (reverb) parameters via the app.

Del-Verb Pedal

Sound: 10/10, really unmatched in terms of quality and feel.

Features: Limited - why no midi control? I have to give up tap tempo or reverb because you can't have the reverb on without having the delay on if you want tap tempo... what a short-sighted design. Midi integration or even the ability to add a footswitch for tap would make a massive difference.

App: Meh, it connects sometimes and sometimes it doesn't - if my phone closes it's screen for too long (because I'm not touching it and am playing the guitar...duh) it loses connection and you have to restart the app. It's also very laggy...

Overall: 3.5/5 - The sounds and feel are incredible, but the lack of midi integration and the poor functioning of the app really limit the full use of this pedal. YMMV, especially if you're a set-and-forget kind of player. All that said, I'm still going to keep the pedal because it sounds amazing...

Sounds amazing but I have 1 issue with it.

You won't find a better sounding pedal. My problem is the tap tempo. If I want to use that live I you will lose the ability to keep the reverb on. The left switch turns both on or off. If you don't gig it's not the big a deal but for me it's a deal breaker. Either I have independence or tap. Come on, really? My stupid Nux pedal could do that. Sure it sounded like flatulence but it was intelligent. So I'm going to have to throw down after all for the Golden and Starlight. In case you didn't know. Now you know. Because nothing sounds better. For real.

Absolutely Amazing

Worth the price. Saves room on pedalboard. Provides for all my reverb and delay needs with more options and combinations than I might ever use. The sound is very full of character. I can't say enough. This pedal does everything I need it to do and leaves me without needing to look around for a reverb or delay to fit all my needs.

Won't Work / Won't Connect / Won't Update / Won't Pass Audio

Out of the box. Ample Power. Blinks and won't connect to app.
