Review: Non c’è storia! - Universal Audio produce migliori simulazioni Fender e VOX attualmente in circolazione. Suono pazzesco e dinamica da vendere!
Review: I Think You'll End Up Wanting Two - Well kinda. I think if you were looking for an amp free rig this would be the way to go if you were trying to eliminate some sort of Vox. It sounds like a Vox, feels like a Vox, can be adjusted just like a real Vox amp. But I tried one and sent it back and bought a Boss GX100. With a bit of a discount because the one I bought had damaged packing and had been out for a trial I didn't pay much more for the Boss than the Vox box. For the price the UA pedal is quite an expensive choice IMO - but it does perform very well if that's what you need - a small box instead of a weighty valve loaded Vox. For me the Boss GX100 pretty much does the same amp sim but it also has all the pedals built in as well - so for a guy like me that's just had a heart attack and is looking to downsize / reduce equipment weight / and simplify gigging, the Boss is an obvious choice. I'm recycling the Helix XL to do this as well. And the amp has gone in place of two 10" PA speakers that work off the GX100. I think the UA Vox is superb if you want a Vox sound (only). I can't find a single thing I don't like about it and the build quality is superb. But the Ruby only does Vox and I can see a time a few months out when I would also want to load the pedalboard with the Dream '65 or the Woodrow.....so that would be a pair costing £650? I'm a player and can't justify the hours I'd have to play to pay for those. If you are buying a Ruby instead of say a VOX AC15 I get it. But I think you're going to want two on the pedalboard - so......

### ⭐⭐⭐⭐⭐ UA 63 Ruby, simulation d'ampli à lampes vox AC30
*by P***N on 23 March 2024*

Je n'ai jamais utilisé d' AC30 de chez VOX; une fois passé le temps d'accoutumance, je trouve cette pédale superbe: on peut obtenir des sons clairs ou saturés extras sur des micros simples bobinages (Stratocaster, Télécaster) ou doubles bobinages (Les Paul, Duesenberg); le toucher est très sensible et on a la la possibilité de permuter entre 2 sons dont un mémorisé (un clair et un saturé par exemple). Dommage: pas de possibilité de mémoriser plus d'un son. P.H.Galvin
