Very good eq for the price love the illumination option i have a red mustang interior red and black the red lights just compliment my car only a 4 band eq but makes huge difference once installed i had to wait a while to get it installed because i needed a 4 channel amp and this was delivered way quicker then my amp was S.E has great delivery service but now its installed and my sound is awesome i can honestly say my mustang is the best sounding stang around my neighborhood.

worked well for my needs

This product fit right in with my entire boss audio system. I mainly used this equalizer to tune my 10 inch boss phantom subwoofers down so that they would sound at their best when adjusted from my head unit, without having to much bass. the price was good, the design is cool! its all about knowing how to work with what you buy. for having a custom built, self installed $365 system in my 08 single cab f150, I can proudly say my system sounds a whole hell of a lot better than a lot of those "MEGA BUCK" systems. this product made a good addition to my sound quality in my truck.

My Sony component sound more crisp hitting bass in this EQ sound great, Thanks Sonic Electronic for fast and accurate shipping.

Good Buy $

This is a good EQ. for the money. However, the preset frequencies on the mid range control is set too low. Some other brands controls are set at 2.5K instead of the 1K of the Boss EQ1208.

Very nice addition!

I originally got a Boss AVA 1215 eq. Not bad little eq in it's own right. I really like this 1208 model better. It is much cleaner and has up to 7 volt output. Yeah it only has 4 bands of equalization but it works very well for me. I setup all my eq's and stuff to classical because of the wide range of tones and also the various instruments. The system virtually handles all types of music with only minor changes to accent what type of music you listen to on a regular basis. As always, Sonix and their great staff treat me right with quality service, products and sane pricing.
