I purchased the pedal with the intention of using it with a classic Stingray through a Markbass amp.
I have it sitting at the end of my effects chain and after playing around with settings for a week, it has done what it promised. That is, it has taken an unruly, aggressive horse of a signal and given it balance and clarity. If you play a Stingray or a bass with a similarly pronounced and nuanced character, it is a great addition to your armory. It will lend balance. You know the way your Stingray demands that you play with a bit more finesse and deliberation? That's not a bad thing in itself. But when you're playing live and your fingers go searching for volume and pronunciation in the heat of battle, a compressor will temper your worst tendencies and lend you a balance and consistency of tone that you might not have thought that you needed.
The build is robust, a metal casing that will provide stability and consistency going forward. The settings knobs are solid and clear in that they do what they proclaim to do. The top-set IOs are eminently practical. It does say the wattage is 100W on the casing but 9W is the reality.
For the price (€40 in Feb 2022), it's amazing. Makes a big difference to my tone, which is exactly what I was missing. It lacks features available in pricier compressors but as a basic tool at this price point, it excels. I'm very happy thus far and hope others will be too. Plus, come on. €40 for a quality piece of engineering should not be missed.
