What the Wahcko Bass Does
The Wahcko Bass is our bass-specific wah pedal—built to let deeper frequencies shine through while preserving that classic, expressive wah character.
We redesigned it to pass more low end and adjust the sweet spot of the sweep so it responds beautifully to bass guitars.
If you want a wah that keeps your low register intact and adds dynamic expression, the Wahcko Bass does exactly that.
About the “Achenbach Series”:
John Achenbach is a Storyboard Artist and Animation Professional with a long history on the legendary show “The Simpsons” and a guitarist/musician. The “Achenbach Series” is the result of a loving friendship that has developed through the years out of mutual respect for what each of us does!
Here’s a little insider’s look into his process for coming up with his designs, using the “Achenbach Series” Tubedreamer as an example:
“You just can’t beat nature. For inspiration, I researched the first amplifier tubes to design a JAM pedals character and found this Fleming tube from 1904. Then a friend recently posted a real pic of a virus under an electron microscope. Damn.. that’s freaky.” John Achenbach
