Good choice for a shimmer pedal. Like the JHS hall reverb it is really astonishing quality for the money.
The shimmer is nicely integrated in the reverb and sits just a little bit on top in case of octave up shimmer. If you want an explicit octave up apart from the reverb, this is not the best (but I don't like that kind of shimmer).
It can go really long en fully wet which opens a lot of ambient possibilities.
It is well eq'd. It keeps some subtile definition, also in the lower regions with the octave up, wich makes it very usefull to play with. It also has some subtile modulation I think, wich makes it more musical.
it is a really nice shimmer reverb !
