Wide Variety of Onboard Effects to Nail Classic Floyd Tones

Combining biting fuzz, multi-head tape-style delay, and vibrant modulation effects, the Keeley Dark Side Workstation pedal is tailor-made for Floyd-esque psychedelic tone. The fuzz is based on a 1977 op-amp fuzz circuit, tweaked for maximum sustain and clarity. The multi-head tape delay effect offers 12 syncopated delay patterns, and the modulation section provides Flanger, Rotary Speaker, U-Vibe, and Phaser effects. And an Order switch makes it easy to switch the order of your effects on the fly. Get even wilder with your effects by connecting an expression pedal (not included). If '70s psychedelic and classic rock tones are your thing, Sweetwater highly recommends that you check out the Keeley Dark Side Workstation pedal.

Epic Effects Workstation

Keeley's Dark Side Workstation is designed for huge, sweeping tone that drips with character. These effects aren't just previous Keeley effects re-packaged in a new pedal. The Rotary Speaker effect is more chorus-like than their Monterey pedal. The Flanger is a circuit never before used by Keeley. And the U-Vibe effect has a deeper range and more throbbing intensity than previous U-Vibe incarnations. The 4-stage Phaser effect is the only exception - it sounds as sweet as it does in Keeley's Jimi Hazel Phase Delay and in their Bubble Tron pedal (hidden Bank 2 mode).

Keeley Dark Side Workstation Multi-effects Pedal Features:

  • Multi-effects pedal designed around the iconic tones of Pink Floyd
  • Onboard Fuzz, Delay, Flanger, Rotary Speaker, U-Vibe, and Phaser effects
  • Fuzz and Delay/Modulation sections are independently switchable
  • Multi-head tape delay effect offers 12 syncopated delay patterns
  • Order switch changes which effect is first in the chain
  • Connect an expression pedal (not included) for even more fun

Fantastic Pedal!

I recently purchase this pedal and I am very satisfied with it; I own a reissue of the original 77 Op-Amp fuzz and adding the toggle for additional tone modes makes this version very versatile.

Delay is excellent, can dial in classic delay sounds very easily even tough there is no tap tempo option.

Modulation combinations are excellent allowing you to run to effects at once!!!

I will like to give a a shoutout to James Lorann; he is an excellent sales engineer, always on top following up on my orders and keeping in touch to check on my gear!.

Pink Floyd all night long!

There is a guy who plays in a taproom where I play who does a Led Zeppelin night every December. The brewery even brews a special triple IPA called Stairway to Heaven for those gigs. Let me tell you he is great! But I got jealous, and I convinced the brewery to let me do a Pink Floyd night, all acoustic! They even brewed a beer for Pink Floyd night, Dark Side of the Beer! I was angling for Wish You Were Beer, but they wanted people to drink the beer and that name is not really screaming drink me. Anyway I think that I am qualified to review a Pink Floyd in a box pedal having done Pink Floyd night 4 years running. This thing is outstanding! It has earned a permanent spot on my acoustic pedalboard! The delays alone are worth the price, the Fuzz is just the right amount of fuzzy and the filters are top notch. It is literally on all night long! The learning curve is a bit steep because of the color coded delay settings so I keep the one page manual on the floor to remind me but Dang! I love this thing!

"If only you knew the power of the Dark Side"

What a fantastic pedal from Keeley Electronics. I bought this for the modulation and tape delay but ended up really digging the fuzz side. I've sold every fuzz pedal I've tried and this one has something special. It goes without saying that the Dark Side can do a lot of signature Gilmour sounds but that is just scratching the surface. I'm not a fan of complicated knob turning but don't let the controls scare you as it is very user friendly once you understand the creative layout. Tone for days and tons of inspiration to be found in this little black pedal (it's much smaller than I anticipated). Thanks to Sweetwater for delivering exceptional customer service and speedy shipping. If you are on the fence, listen to the Dark Side of the force and snag one of these.

Love this workhorse of a pedal!

Being a huge Dave Gilmour fan I was so excited to get this pedal especially for the delay part of it. I was gonna give 4.5 stars because you can't use any of the modulation effects with the delay but I mean c'mon sometimes we (or at least I) expect so much from our pedals. At this price it's an incredible deal. You get all those sweet phaser/uni-vibe and flanger/rotary effects with an option to blend them for unique sounds. The fuzz side is great too and is very versatile. And of course the delay is so magically beautiful! The folks down at Keeley and Sweetwater share a passion for providing the best products and customer service you could possibly ask for. Thanks Sweetwater and all the people at Keeley for this absolute gem of a pedal!

Inspiration, motivation, and fun

This is one cool pedal. I didn't need this, it was a whim to have a fun toy for my little practice amp while recovering from surgery, which made it difficult to traverse stairs to my performance gear. I've had more fun with this pedal on that little practice amp than I have in years. Its variety of modulation, delay and a very versatile fuzz, offers many combinations of creative vibes. With the addition of the Mission Engineering expression pedal, I can't stop grabbing my guitar to play with this thing. It's becoming a problem, oh no.
Yes there are limitations to its versatility. Specifically, you can't use the delay with the modulation effects simultaneously. So it nice if you have an extra delay or reverb coming out from the Dark Side to add some sweetness to the modulations. My practice amp lacks any reverb or other effects, so I added a EH Canyon delay for this purpose. The delay in the Dark Side is very cool too. Again, add that expression pedal to it and it's some serious psychedelic fun. I do hope they offer a deluxe version of this some day that gives the delay its own switch. Maybe also an output for the fuzz and modulation for a front end delivery to the amp input, with an additional in and out jack for using the delay in an effects loop. Perhaps Stereo outs, and a switchable mods to go to either the amp input or the effects loop would be even cooler.
While I intended this for use with my guitar gear, Bass is my primary instrument of choice, so I had to give it a go. It sounds freaking awesome. I run my main bass rig with a dual amp setup in wet/dry/wet, and there was no discernible cut to the lower frequencies, but the dry amp holds up the lows anyway. So I tried it briefly in a small bass combo amp to see if I was loosing any bottom end. I didn't feel like I was missing anything, but I will need to explore this a bit more.
Over all, the Dark Side is Great fun for the guitar or bass, and it will inspire and motivate you to new musical adventures. Thanks Keeley and Sweetwater for providing me with a fun distraction from my surgery recovery time.
