I've used (and rejected) a lot of reverbs recently. The Golden Reverberator pedal is very exciting to hear in person. This is doubly so if you are after the classic Lexicon sound.
I currently use the UA Lexicon 224 plugin in the studio, and have loved it since I got it. Also this year, for live performance (and sometimes in the studio), I've been using a Meris Mercury X reverb on synths, guitar, and vocals. Mercury X contains emulations of the Lexicon 224 sounds. They are quite usable, but they are perhaps more of a 'nod' to Lexicon, than an accurate representation. No offense to Meris. They do AWESOME work, and I will continue to use a few of their pedals, including the Mercury X.
However, when I first used the Golden Reverberator, it was a slap in the face. But, like a nostalgic slap (feeling) that suddenly jumps forth into your awareness. This pedal is an amazing thing hear on stage, and in a compact format no less. Time will tell how well it does 'subtlety', but my initial impression is that it should hold up. Well done, UA.
Back to reality: The pedal seems very solidly made. It is expensive, as are most UA devices. But they did not miss the target here: There is no other way on the planet that you can get that palpable, dense, shimmering reverb sound, without dragging a very expensive rackmount effects unit around. It is designed to do a couple things extremely well. So, if you want shimmers, reverse reverbs, or unusual early reflection patterns... you won't find it…
