This is a very useful device where it actually helps “tailor” the music to your liking be it with headphones or in your stereo system. The four controls on the front allow adjustments to be made in the following frequency range – bass (20Hz), mid-bass (400Hz), mid-range (2kHz) and treble (8kHz). The adjustments made are clearly audible and it does “enhance” the music presence in our setup. A toggle switch on the front allows you to defeat any adjustment made and just allows signal pass through. So you can play around with it and hear if you like it with the adjustments made or not.
Cosmetically, there are some minor scuff marks here and there but nothing major. We don’t have the original box but will securely pack it for safe shipping.
