I like on G-Sonique, that they always do things a little different than others or present products, which have their own individual character or are a little off-maistream.
I found that Psychedelic Tunnel T1 finally is a fresh, creative, different approach to the reverb theme, which enables a wide range of more spacious, ambient, unusual sounding reverbs with a very interesting character.
Usually I'm mainly - if any - using some tape echo and / or spring reverb, but this one I only tested shortly and liked it. You can get some nice, pulsating reverbs due to 3 combined sets of LFO modulation, but what I like most on it is the dark energy control, some kind of detuned octaver, which gives a very special, great sound to the reverb.
Not only usable for Psytrance, Dub, ...
Just for fun I even tested it with the lead channel of high gain guitar amp sims, and although you usually don't use reverbs and high gain, as this doesn't sound very well, the T1 also in this combination sounds very interesting and nice, the guitar tone changes to some kind of doomy sounding organ/synthesizer-like tones, which sound and work great and unusual also in a heavier or even metal context.
Another nice and a little weird combination is using the T1 in combination with some phaser, Leslie or Univibe, or with one of my all-time favorite pedals, the Electric Kingdom (also from G-Sonique). Or eg. try it with a B3, Rhodes, Bass or some percussion to make them sound different, new and interesting.
A very good special reverb for people who are looking for some fresh, new sounds.
