Oops! JHS made an uh-oh, but this mistake is anything but. The Fumble JFET boost effect pedal delivers a tone accidently introduced in their NOTADÜMBLË V1 pedal, now in a standalone enclosure that provides the long-cloned history of a Dumble BBC-1 circuit that was actually sourced from a 1970s Barcus Berry piezo acoustic preamp. The history is messy, the reasoning is complicated, but the sound is superb.

This two knob clean boost, inspired by a clone of a clone of a clone of a etc., performs JFET boosting with a unique control scheme that shapes your sound like no other in its class. The output control works as such—crank it up or turn it down to the desired output volume. The input control, however, behaves differently than expected. When the knob is fully to the right, it can be considered as a bypass for clean JFET boosting. When the knob is turned to the left, bass frequencies and gain start attenuating simultaneously, resulting in a slightly thinner, but overall tighter response. No other boost delivers this sort of shaping, and can be assigned the "secret weapon" label when applied properly.

Here's what you do: use it as a permanent tone shaper and boost at the front of your board. Set it however you want and never turn it off. Alternatively, the Fumble can be the overdrive lift you've been searching ages for. Rather than muddying with another pre-drive drive (what a headache), the Fumble adds more level and color to your favorite characteristic dirt. Push a driven amp, boost your board at the end of the chain, or, if you're feeling adventurous, try it as originally intended in the 1970s with an acoustic guitar. Let us know what you think about that one.

With analog circuitry, true bypass switching, and standard nine-volt center negative power requirements, the Fumble JFET boost proves that some wrongs can, in fact, be made right.

  • JFET boost inspired by Dumble's "repurposed" 1970s acoustic preamp
  • Input bass and gain attenuator control
  • Output master volume control
  • Analog design with true bypass switching
  • Standard nine-volt DC center negative power requirements

Dead batteries
Format: Board book
The book itself is nice but it came with dead batteries. Now I have to buy and replace the batteries before I can give it as a gift to a toddler who loves pushing the buttons. If not for that, would have given it 5 stars. But the inconvenience of finding the batteries in the first place when I shouldn’t have to is extremely annoying.

Good, cute talking book. Good audio
Format: Board book
This little book has pretty good audio and has lasted quite awhile. The story is cute, my little dude liked it, and it was well made. Thick board book so it's perfect for little hands. (Amazon VIne people, please accept me into your ranks. I know this review wasn't as good, but IDK what else to really write, I got this for my nephew for Easter I think two years ago and it was destroyed after awhile intentionally. I don't have the greatest memory of it, but we kept the speaker part after because he liked it before we finally just got rid of it while cleaning...sorry lil dude if you ever come across this review, I'll get you a new one if you're that passionate about it)
