This little box - busy looking on most sides - is very competent at what it says to deliver : a vintage inspired but accurate true parametric equalization which some creature comforts.
The equalization part is, in a few words, excellent. The ranges for low-mid (40Hz-700Hz) and high-mid (300Hz-6kHz) frequency selection are totally usable. Did not measured the +/-18dB with precision tools, but seem accurate. The manual gives quite a few propositions for settings regarding if you intent using it as an equalizer or en effect, but gut feeling is not restricted as an option. HPF and LPF are useful whether you need to clean a bit of ramble or, again, use them as an effect.
The cost of this product is mainly because of the fact this is a analog pedal, which requires quite another level of engineering. The size for value proposition is pretty good in that regard.
The fact this little box can be used like a D.I. with phantom power may not be useful to everyone but can come in handy, especially for bass players who uses it as a cab sim. Early in your chain, the parallel output can be used for your tuner or as a secondary chain, if you are creative.
Construction wise, the box is your standard aluminum box, but the knurled metal buttons give a premium felling when making changes to your configuration.
Of course, if you need a simple equalization box for low-fi effects or such, this is overkill in every way. But if you need a sim cab with precise equalization in a small box, or need to tinkle precisely your mids to make your drive pedal to the edge, it's a solid choice. Bonus points for the color, which stands out on any pedal board (yes, it can be important at times :) ). I used it with a variety of instruments (basses, guitars, cellos, keyboards) and never been disappointed.
