Product Description

This system allows bass guitarists complete control over their instruments
A dynamic balance circuit, a master volume circuit, and an EQ circuit
to separate bass, midrange, and treble while allowing you to control them with 2 concentric/stacked knobs
The control should be rotated in a clockwise direction to boost, and in the counterclockwise direction to reduce
The flat response is controlled by a detent in the center
This feature enables the user to sweep over the mid-frequency range from 100Hz to 1KHz using a variable frequency knob
By changing this, you are able to boost or cut a frequency

Questions & Answers

Do I need to convert the emg pjx set to work with this?

Without a doubt. EMG manufactures an upgraded (metal) knob set for the BQC as well. Preamps often have plastic knobs, but the ones included here are kind of cheap and tacky.

What if I want to use them with other pickups, like an EM car?

I recommend sticking to the intended use of this preamp since it was designed specifically for EMG pickups.

Do the knobs in this ad not include pickups or does this ad only refer to knobs? If so, will these knobs work with conventional pickups or strictly emg?

The EMG soapbars were purchased to replace the Spector Time Pump for wall usage that had been mounted (poorly) in an 18 volt setup with two Spector Time Pumps. This kit includes the preamp, the knobs, and the You could probably connect the EMG pickups to other pickups, however, but the advantage of the solderless wiring is that you can connect them to other pickups.

Can I connect all Quick Connect ports to this device?

It has all of the quick connect for pickups, batteries, and the input jack.

Selected User Reviews For EMG BQC 4-knob Active Bass Preamp System

The tone of my voice is excellent
5/5

My original preamp on my Spector 5LX had been damaged. I purchased this kit to replace it. Due to the fact that they are EMG 40TW pickups, the stock volume controls were used on the two pickups as they require a switched pot (which is not included in However, the kit was easy to use without the blend and volume pots (I now realize that I should have bought the EMG BQC Control instead of the When the metal knobs designed specifically for concentric pots are installed and added to the resonator, the tone is magical. Preamps are so much cleaner and better than stock versions. Due to the fact that I wired this as 18V, that may be part of the reason, but this setup truly accentuates the Spector sound. My favorite feature is the sweeping mid range, which gives me ample tonal options. I'm very happy with the.

This is a good 3 An EQ with bands
5/5

A Steinberger XM-900 recently came into my possession Since passive controls were present on 2 of those, I decided to go with this control system since it was more flexible. In a nutshell, the XM-92 MIA active EMG's come standard on 2 and the previous owner had already drilled an extra hole for an EMG boost switch, so I didn't feel bad about drilling any new holes. Keeping brand consistency was also important to me. There is a powerful tone system in here There are four levels of volume, a stacked bass-treble and a sweepable mid. This is a feature that I like particularly. There are some basses with Aguilar OBP on my shelf There are only 2 frequency choices on the 3's (which are also excellent), which can be toggled with a switch on the control panel or with a push-pull It's true that the options are effective, but they're not the same as sweeping. The people at EMG made an excellent preamp.

Installation is quick and easy
5/5

It is remarkable how much better it is than the previous Originally, I was considering going passive with this bass, but decided to get an offset pickup that matches my PUPs instead. EMGs were active when it was deployed. It's definitely an improvement in terms of gain, and there's a lot more control over the sound than what I removed.

I am very pleased with the It's nice to have it upgraded
4/5

My Spector Rebop bass came with a tone pump, so I purchased this one to replace it. Together with the EMG, this results in This bass received a significant upgrade when it was fitted with 40DC pickups. The sound is great, and the control is excellent. The solderless system makes it easy to install. It took me a little over an hour to install and play it. All in all, not bad.

This controller is awesome
5/5

You have a wide range of flexibility thanks to it. You have an infinite number of equalizing options thanks to the 12dB on each controller. This is not a noisy home. The following are the components I have installed in my Ibanez SR886 It sounds fat and great because it comes from Japan (6 strings). My personal opinion on the concentric knob is that I'm not very satisfied with it because I prefer quick access to knobs during a song, so having them independent gives you greater ease during a song- It is accessible. The book is definitely worth a read.

Though the sound of this system is excellent, I am not so thrilled with how it feels
4/5

The sound of this system is excellent, but I'm a bit disappointed in the feel of the concentric pots and cheap It's obvious that these components are not high-quality.
