Have tried a lot of compressors over the years and never really been 100% happy. Purchased the Empress Effects 'Blue Sparkle' about a month ago and waited to post a review as i wanted to get familiar with the pedal, before doing so.
Empress suggest some settings in the manual to get you started, and from there its a joy to alter those setting, and hear the difference it can make to your sound. I particularly like the 'MIX' knob, allowing you to mix wet and dry signals. I've used it on both active and passive basses and now that i am familiarizing my self with the pedal is can easily dial in the sound i want.
The unit itself is of excellent build quality, and looks great on my board.
More detailed reviews are to be found on is the site i used to do my research and would I highly recommend it, prior to making a purchase.
I'm extremely happy with my purchase. Thanks to Thomann for excellent service and delivery , as usual
