All guitar playes need this
This EQ first of all has great sound quality. No issue with noise. Put this in your effects loop. Take any high gain amp channel and shape it into the sound you hear on recordings. It's all in the EQ. All of the classic rock tones, metal tones, fusion tones......it's not your amp; it's your EQ.

This unit meets the need
31-band EQ's have several uses in the chain of audio production, several of them may only require a single channel. While it would surely be "economically prudent" to buy two-channel EQ's from the start, when the need requires a single channel only (as with a single microphone installation, perhaps,) the dbx 131s is a reasonable choice. I have not found any reason to question it but I would suggest you take all the time necessary to understand where an EQ works and what it cannot do. It can, along with other tools in the chain, clean up and clear up certain issues, but know that it does not replace processors designed to limit, shape or expand the signal. I use mine to help isolate a particular sound quality, and I rely on additional tools to complete this process. For what it does, it works transparently and well.

A must have for bassists
Simply perfect for trimming down those annoying frequencies and shaping your sound the right way. This is a very nice EQ and probably would work well for Keyboardists as well.

Bought 2 Both Useless
So...Because of the decent ratings I went ahead and bought this unit. 1st one started to hum terribly and start popping after only a week. I changed out all of the cables...Nothing stopped the hum until I pressed the bypass button...I was refunded, figured it was a lemon and bought a second one. At first was fine then within 2 months SAME EXACT ISSUE. Humming, popping distortion...Press the bypass button Crystal clear. Cannot recommend this unit.

This is my third purchase of a DBX EQ for different sections of my PA rig and I'm very happy with the general build quality and performance of the units. Light but sturdy, just enough features to be very useful without being too complex, and they do a great job to set up the sound perfectly for each venue that I sing at. This single channel unit is being used for my microphone and is just what I needed to get the type of sound that I want from the mike. It rack mounts very easily and has either XLR or quarter inch jack inputs/outputs so it's quite versatile. I'd recommend this type of EQ to anyone involved in live music production as it really does help with screening out feedback at high volumes without losing too much of your mix, plus you can alter specific frequencies in your sound to best suit the acoustics for the room you are setting up in. Good job DBX!

Chain - Guitar > Alesis Q2 > Dbx131z > Vox AC15 produced an annoying mid-to-high frequency hiss (no guitar signal; mid freq.- high freq. sliders at +12dB). When the Dbx131s was removed, the noise was gone. When the Dbx131s was replaced by an MXR Ten band EQ with sliders at equivalent position, the noise was gone. Very dissappointing. Unit returned and awaiting refund.
