Useful Tip 

Use your JAM Pedals Wahcko as a tone shaping tool.  Turn the Wahcko on, leave it at the toe down position, and experiment with the six different settings of the rotary switch. The JAM Pedals Wahcko offers many interesting tones for your lead or rhythm overdriven parts. 

JAM Pedals Seagull: To properly operate the Seagull effect, make sure your guitar has passive pickups. 

  • Engage the effect with the toggle switch 
  • Turn your guitar’s volume knob all the way up 
  • Change the effect’s pitch by manipulating your guitar’s tone pot

Artist Quotes 

"I’m a mad user of JAM Pedals! I probably have more Wahckos than anybody in the world!  The reason I use Wahckos is because of expression.  The moment I played a Wahcko, the type of expression was undeniable.  It was so human like in a way that it just touched my soul." Nile Rodgers

“I love the sweep of the Wahcko, very vocal like and sweet!  What a fantastic wah!” Steve Lukather

“The Wahcko is fantastic! Now I finally have a great wah wah pedal!” Bill Frisell 

"JAM Pedals make the best wah pedal of all time as far as I’m concerned.  It has more dexterity than anything else.  Best wah-wah I’ve ever had and I’ve had a bunch of them!" Richie Sambora

"The JAM Pedals Wahcko is amazing.  Ive never actually owned a wah before because I always found them a bit underwhelming but this is very grimey and musical!" Ruban Nielson

“I absolutely love it!  Beautiful job!  Every setting on the switch sounds great and the vocal sweep is perfect.  Finally, finally, after all of these years a wah I will actually use and not want to sell or destroy!” Julien Kasper

“The Wahcko exhibits a rugged, broken in maturity.  It sounds like a sweet old wah with lots of miles on it and provides superb tone sculpting choices for clean and distorted amps!”  Vintage Guitar magazine

“One of the best of its breed”  GUITARIST magazine

"Love the smooth action of the JAM Pedals wah pedal and how you can change its voice to accentuate your guitar’s natural tone." Sean Ono Lennon
