A Clean Boost Built on Legacy

Get to know them!

JHS has a knack for reimagining history’s most coveted sounds, and The Fumble is no exception. On the surface, it’s a simple JFET clean boost, but underneath, it’s a re-creation of a legendary amp circuit, identical to the clean section of the JHS NOTADÜMBLË V1. It’s a sound that’s lived in some of the most sought-after and expensive amplifiers ever built, tracing back to a humble 1970s acoustic preamp. Refreshingly uncomplicated, The Fumble’s two knobs handle everything: Output sets your master volume, and Input simultaneously attenuates bass and gain at the front of the circuit. Sweetwater guitarists find the responsive design moves easily from full and loud to thin and tight. That flexibility lets The Fumble work as a front-of-board buffer, an overdrive pusher, an amp slammer, or an end-of-chain solo boost. However you set it, The Fumble puts one of history’s most sought-after tones right at your feet.

A heritage three generations deep

The Fumble was born from another JHS project, the NOTADÜMBLË V1, which shared a similar goal: a faithful production version of an iconic amp circuit. That JFET preamp design was lifted almost part-for-part from a 1970s acoustic preamp, and built into one of the most iconic amp models ever created. JHS tells us that “The Fumble is a clone of that clone of that clone, three generations deep,” built to enhance your tone in myriad ways. Use it as a buffer to tighten everything downstream, or push the front of an overdrive for a second gain stage. You can also put it in front of a cranked tube amp to slam it for a bigger, more articulate attack, or simply crank the output for solo boosts sure to cut through any mix.

JHS pedals are handcrafted tone machines

When you plug your guitar into a JHS pedal like The Fumble, you're tapping into the care and passion that few manufacturers put into their products. Each JHS pedal is handbuilt and tested by the JHS team in Kansas City, Missouri. Because the company designs its pedals for specific musical purposes, we're sure there's a JHS pedal that's perfect for any player's rig.

JHS The Fumble Features:

  • JFET clean boost pedal identical to the clean section of the JHS NOTADÜMBLË V1
  • Straightforward 2-knob controls for simple adjustment
  • Output serves as the master volume to set the level
  • Input simultaneously attenuates bass and gain for dynamic tone shaping
  • Works as a front-of-board buffer, an overdrive pusher, a dirty-amp slammer, or an end-of-chain solo boost
What is Certified Open Box Gear?

At Sweetwater, we're so picky that what we call "Certified Open Box" is actually better than what most music retailers sell as "new" gear! Our gear hasn't endured hundreds of people a week plunking away at all the keyboards, fumbling through Stairway to Heaven on every guitar or playing with every fader and knob on a mixer or control surface.

Certified Open Box (also known as a demo) means we’ve had it out of the box for our YouTube channel, displayed at events, tested in our studio, or maybe it was in a customer’s hands for a few days and isn’t ‘factory fresh’ as a result. Every Certified Open Box item we sell has Sweetwater’s 2-year Total Confidence Coverage™ warranty and has been tested and verified up to ‘new’ specs by our factory-authorized technicians to make sure it’s in perfect working order before we ship it to you.

When you buy a Certified Open Box item at Sweetwater, you get:
  • 2-year Total Confidence Coverage Warranty™!
  • Products inspected and tested by our factory-authorized techs, guaranteed to function like new (or better)!
  • FREE shipping on most items
  • Equipment that will MEET or EXCEED your expectations!
