I have put this preamp in two of my basses now and I absolutely love it. Super easy to install with no issues!!! This preamp has several cool features I love. For me the best part is being able to select the exact mid frequency you want to boost or cut. It’s also super cool that there are four different curves you can choose from on the treble boost/cut. All these features make for a very versatile preamp you can use to dial in any sound you want right on your bass.In response to the other review on here I don’t know what that guys problem was. When you install the knobs you just have to make sure you leave a little space between the knobs and the nut below them. All you have to do is just lift up slightly on the knob while you tighten the set screw.

"A waste of money."

Dont even bother with this junk.....Will never EVER buy again. EVER!!!!If I could give this system a 0 instead of 1 star I would. I bought this set close to a year ago and it has been a nightmare the whole time. The biggest problem with this system is the "d" shape shafts on the concentric pots. I tried knobs that I had ordered for this upgrade and they did not work very well because the upper small knob kept dragging on the top of the bottom larger knob. I contacted EMG and they said that they sold knobs on their website so I ordered those knobs. They did the same thing. I contacted them again and they wanted me to send them the set with the plate where the pots were attached to. I sent them the whole thing yet they could not fix the problem and sent it back to me with no solution. They are not willing to give me back my money so a year later and I am still stuck with this useless set from EMG. I have installed many high end preamps and also cheap preamps from China and all the pots are always smooth. EMG should be embarrassed to sell this junk. Right now it is still in its box not being used because when I tried to use it the knobs kept sticking and it was very embarrassing. NEVER AGAIN will I by from EMG. They have really let me down. I am at the process of contacting the commerce department in their area to file a complaint. All this calamity because they want to save a buck.
