Boutique quality that won't break the bank.

The Seymour Duncan SFX-08 Power Grid Distortion Pedal is a high-gain, solid state distortion stompbox capable of myriad tones, thanks to a 3-band active EQ section. The Power Grid is a perfect distortion pedal for all genres of rock.

As a guitarist, when you need power, it's generally because you want to lay down chunky rhythms or you need to bust out a blazing solo. Enter the Seymour Duncan Power Grid, designed to provide powerful overdrive and distortion, The Duncan Power Grid is a guitar pedal suitable for rhythm and lead playing, thanks to 5 stages of class-A discrete circuitry cascaded to provide nearly 100dB of gain. Now that's power.

But the Seymour Duncan Power Grid is not an untamed beast. All this raw horsepower is managed by a multi-element gain and volume control system that gives you fine control. For example, if you crank the gain, you'll get a very thick, saturated "Modded British" distortion, reminiscent of the big guitar sounds that defined metal. But if you back the gain off, you'll get a very responsive "crunch" distortion similar to the Rhythm Channel on the Seymour Duncan SFX-03 Twin Tube Classic. And in between there are varying levels of overdrive and distortion to fit your ideal sound.

With the Power Grid distortion effect, your tone is further refined thanks to a three bands of active EQ. Each band allows for up to 12dB of boost or cut at frequencies selected for maximum control of the electric guitar. This allows you to create tones with a far greater degree of surgical precision than what's possible with any distortion pedal with passive EQ. With all the power and control built into the Seymour Duncan SFX-08 Power Grid, it could just be the last distortion pedal you ever buy.

This is the perfect pedal for all rock, blues and fuzz. the metal is a bit too fuzzy for me, but i am sure most people will still enjoy it. i like the 9v adapter so i can use it on my pedalboard without a problem. everything is straight forward, no guess work here. would be nice if there were some tubes on it, but it still kicks without them. if you are not sure what distortion is right for you, start here, you may never need another one.

The best pedal I have

By Anonymous

from Undisclosed

I been a guitarist since 14 years old. I'm 41 now. I have lots of guitar effects from Analog, Digital Floor Effects Processors, Rack Mounts (I won't mention the names of the products because they might be offended) If there is a gear rehab, i would be there already. Power Grid is the best pedal for me. It is very universal. And it works great with any kind of pickups. Turning the gain knob at 1 o'clock then you can have EVH sound. At 12 o'clock you can have Joe Satriani. At 10 o'clock you can have Santana. This is my last distortion pedal on my pedal board. Thanks Mr. Seymour Duncan! Praise the LORD!

Great Vintage Distortion

Simply the best distortion pedal i have ever bought and i have been playing for thirty years.I have never been disappointed with Seymour Duncan products or Musician's Friend. This pedal is great for classic rock, mellow blues, even metal, you just have to play around with it a bit and it will deliver. If you like their pickups then get their pedals.

This pedal is serious about tone.

By RebelRocker'73

Buy it. It's the one to own.
The Power Grid* pedal is very well designed,with the guitar player in mind. Virtually runs the entire range of tones and gain. From moderate,to ultra saturation. The bass,mid,and treble controls DO enable you to dial in the exact sound you want. Basically,filling the place of any other pedal out there. That being said,however,for someone wanting to change tones with the speed of a footswitch,some would probably prefer to still have their other pedals too. I don't need to,because my Marshall has a new Ruby* tube; so I have perfect clean,classic overdrive,and now with the Power Grid* pedal I have a great third-channel overdriven lead tone!
This thing is built like a tank. Will last,and has great tone. The TRUE bypass..(for some reason not mentioned in the manufacturer's product description)..is a TRUE bypass,and is ultra quiet. No noise,and seems to actually condition,or balance the signal a little better than just plugging straight into the amp.
I bought this pedal on sale. Well below half of the original price. Having owned the pedal a while,knowing what I know now,I would pay full price for it if I had to again.

Overall this is a useable distortion for sure. A respected name, plenty of knobs to get at least close to the sound in your head you're seeking.
The Seymour Duncan Power Grid Distortion- Metal jack imputs, metal casing, 3 band eq, vol.& gain. It's very similar to a Danelectro Daddy O which has has the same features. I rate it a little higher overall than the Daddy O. The eq is more responsive on the Seymour Duncan giving it more versatility in sounds.
I've not had it very long, but initially it seems very solidly built. Build quality is high, sound quality is fairly high. I might use it in place of my Boss Metal Zone because it has a thicker sound.
I aquired this stomp box on a clearance. So, value is fantastic. I've paid more for pedals that were not nearly as solid as the Power Grid.


Hi gain on tap that responds very well to guitar volume

Ask me a question

Even though you can get some nice older OD tones, but this pedal was made modern rock.
Active EQ and very reactive controls.
I own too many dirt pedals to list (tube and SS). This pedal can create tones that can be a smooth OD to cutting higain meyhem. All the while able to provide thick higain chunk and also cut lead lines through the mix at the same settings by the guitars volume setting and pick attack. The cascaded gain comes on in stages by increasing the pedals gain, yet still lets the guitar control the level - much like a good tube amp. Great addition to my collection.
