I have been using VL3X for 1.5 years. I've played around 300 short (30 minutes) repetitions, about 75 long (3 hours) concerts with the VL3X and am satisfied. In my opinion, this is a unique and very useful device, that has no analogues in the world. I am an underground garage rock artist, vocalist and guitarist. The drummer plays with me. Most of our concerts are in small pubs, where 50 viewers are big deal.
And we use the VL3X backing track player to play bass guitar track. Very good internal memory - fits a lot of backing track's. I don't know, how much will fit backing track in this device, but I've already uploaded around 100 wav files. This is important, because I use backing track a lot - different in different concerts.
I write a review after reading the negative reviews. Some say, that VL3X are bad guitar amps. But this is not true. A clean brit, 4/12 crunch, scooped amp and tc dark matter overdrive - sounds good to me. There are many parameters that can all be fine-tuned, adjust as needed.
Automation is a great thing. I use it for guitar effects. When you switch from guitar rhythm to solo during a song, I write down the effect change in backing track automation. Very comfortable. No need to bother with effect alternation. You can focus on performance and communication with viewers.
In "do it yourself" underground rock festivals with minimal hardware, we use VL3X to process the lead vocals. Great for all punk rock and modern metal bands.
Some people complained about the VL3X failing fast. But it works for me, despite the fact that one night after the concert with the VL3X I fell on the asphalt. :) And nothing happened.
If there is any doubt about the operation of the device - then I just reboot the device.
Commentators curse VL3X factory presets. I don't use them, it's just a demo. But overall I use a lot of the vocal effects in VL3X, they are all useful. They need to be fine-tuned. Work with the VL3X will be a good task for the advanced audio engineer as well. And for us - rock'n'roll losers - it will take a long time. Combining effects, the VL3X is best for listening with headphones!
It should be understood, that once you buy a VL3X, you will not run with it on stage or repetition the same day - it will take at least a month to study, tune, adjust to your needs and your productions.
