Mostly unusable in live settings
I ripped this thing off my board after playing 4 live shows with it. What good are all the features if you can't use them live? There are a lot of cool functions with this pedal, but here are three reasons why I (and many other musicians) find this pedal to be absolutely worthless for stage use. A simple coding fix could address all of these, but Vox refuses to cooperate with current owners.
1) Tap tempo does not work without a delay engaged. That's right, you can't "tap in" with your drummer before turning a delay preset on. This is just poor engineering. If your delay is supposed to be sync'd to the music, you have to start tapping immediately after engaging it, and EVERYBODY can hear it. When you use a non-digital setting (tape, analog, etc.), tapping the tempo switch introduces the notorious pitch-shifting garble-garble. Every other *decent* delay pedal alleviates this problem by allowing you to set the tempo BEFORE engaging a delay. Not Vox!
2) Tap tempo is not universal, and is hard-coded not to be. That means if you'd like to use a 1/4-note delay for the chorus, then you want to jump into a dotted-1/8 setting for the bridge, your tempo does not transfer. You have to tap it out (see #1 for the garble-garble that will once again find its way to your listener's ears). If you use more than one delay type in a song, this is a deal-breaker.
3) Unusable high-freq hiss. I have owned lots and lots of delays over the years, from cheapo Boss to TC Electronic and Eventide. This delay has far and away the worst hiss I have ever heard coming from a digital pedal.
4) Bonus! This pedal is hopelessly slaved to the concept of the Line6 DL-4 delay. Why in the world manufacturers continue to clone this oversized and poorly designed pedal with all of the current technology we have at our disposal is just plain silly. The DL-4 was plagued with many of the same disappointments found in this pedal; this is what happens when you hire engineers to do the job of a usability/product designer. Manufacturers, please TEST YOUR PRODUCTS with actual musicians in live settings before going to market. PLEASE!
