EMG 57/66 Review (7 String) & Sound Demo

Hello there, back again with another guitar pickup review for you! This time we will be looking at the EMG 57/66 pickups (7 string, 7H)! As many of you know, EMG Pickups is an American guitar pickup manufacturer and are probably the first brand that comes up to one’s mind when active pickups are mentioned!

What are active pickups?

Active pickups are guitar pickups that are powered by a 9V battery. They are designed to ensure a noiseless operation and a low-impedance signal without any loss of signal transmission regardless of the cable length. Active pickups generally tend to sound louder, clear and full but also feels a bit more compressed.

Are active pickups bad?

As you may have already discovered on the internet, there are countless discussions about passive pickups being superior to active pickups. However, it’s just a personal choice and wise guitarists don’t classify guitar pickups this way, instead, they take these as tools to shape their sound for a specific purpose.

Music is our passion!

In my opinion, both are awesome but they are only different from each other. If you want to play with hi-gain settings and want a solid, tight feel while having no noise at all, active pickups are excellent. On the other, passive pickups can also handle a lot of gains and they are almost perfect for any musical scenario as well.

Active pickups vs passive pickups

Passive guitar pickups can be considered the standard when it comes to electric guitars. These pickups are made of magnets wrapped with copper coils around them. So when you hit a string, it interferes with the magnetic field and converts this into an electric signal.

Even though passive pickups usually generate less volume than active pickups, it all depends on the magnet type and number of coil wraps. Their dynamic range is pretty big compared to active pickups, however, they are also more sensitive to electrical and magnetic interference. Especially single coils can generate a lot of hum and feedback under high gain settings. On the other hand, humbuckers can handle noise issues pretty well these days.

Active pickups are manufactured the same way but with less coil wrapping. The signal generated by the pickup then is boosted in the built-in preamp that operates with a 9V battery. Surprisingly, active pickups are almost the standard for bass guitars. For electric guitars, they are becoming more popular every day, however, we can easily claim that they are less favoured by guitarists.

The lower number of coil wrapping will naturally generate a low output. This actually helps to have less interference thus almost no hum or unwanted feedback. Since this signal is boosted by the preamp section, active pickups generally sound way louder than passive pickups. This boosting also compresses the signal, so you end up with a smaller dynamic range.

EMG Active Pickups

To be honest, before I worked in the musical instruments industry, I had very little playing experience with active pickups. But during my service, I had to chance to play and test many guitars with active pickups. I played EMG 60, 81, 85, 89 and single-coil SA pickups on various guitars as well as Schecter‘s own Diamond series active pickups.

I was recording at least hour-long videos using a Marshall JVM205C guitar amp and I can remember the confidence in my playing when I switched to high gain settings. They definitely help with obtaining a high amount of overdrive and distortion without having too much noise as well as providing a compressed tone so that I was able to play more difficult passages easily.

It's a new guitar day!

Whenever I played power chords muted or open, I was able to feel the power of these active pickups. Contrary to popular belief, they did sound very good in clean settings as well. Especially, we had received a lot of positive comments on the Schecter Hellraiser C-1 review video mentioning they never expected active pickups would sound so cool with clean settings.

Having said that, I had never owned a guitar with active pickups nor played EMG 57/66 before! I was looking for a modern metal axe and fell in love with Schecter Hellraiser Hybrid PT-7 electric guitar. Since there was not much online material available on this instrument, I had to trust my experience with Schecter and EMG Pickups and I went for it!

EMG 57/66 review & sound demo

As I always do, I have prepared a video for you!

Signal chain: Schecter Hellraiser Hybrid PT-7 > Cordial CSI 6 PP Silent 6m > ENGL E570 > EBS PG-58 Flat Patch Cable Gold > ENGL Cabloader > Cordial CSM 2,5 FM GOLD 250 > RME Babyface PRO > Reaper > Valhalla Vintage Reverb

Unlike my past experience with EMG active pickups, I must say EMG 57/66 sounds very different and unique! I can still feel and hear a lot of compression and the fact that these are active pickups, but they sound very open and almost feel like a very good combination of traditional passive humbucker sounds with an active pickup vibe.

Both 57/66 features Alnico V magnets and have very pronounced yet smooth mid frequencies. They can easily get into overdrive but still retain the chime and clarity.

In order to show you all possible sounds in a short video, I used the clean channel as well as a boosted clean channel. This clearly shows that it can get overdriven in a matter of seconds, but is still very pleasant to the ears.

Drive characteristics complement Schecter’s acoustic qualities. As you can also hear in the video, in crunch settings, it offers a traditional rock sound without a problem. These pickups can handle a lot of gain by the way (naturally!) Out of my three guitars (single coils, passive humbuckers), EMG 57/66 is able to handle the maximum amount of brutal gain generated by ENGL E570 with a very low amount of gain. Traditional pickups already give in at full gain settings let alone hi-gain switch engaged.

Ever tried coated strings?

As I have mentioned, out of all EMG active pickups I experienced, EMG 57/66 is in another league. I think it offers a great balance between the active pickups vibe and traditional sound characteristics.

I absolutely recommend anyone to try these out if you can! There are many electric guitars on the market that feature EMG 57/66 set, so you don’t actually have to modify your guitar. It’s best to try these modern metal machines and experience this pair of pickups first!
