The TightFuzz Jr is a very flexible fuzz pedal, with a Silicon/Germanium transistor switch and Tight attack switch.

With the popularity of Amptweaker's smaller footprint JR series, Amptweaker added bass and guitar versions of their Fuzz pedals... introducing the TightFuzz JR. These pedals share most of the tone-tweaking features available on their larger counterparts, while eliminating effects loops, lit controls, battery switches and boost features that some players don't need in order to shrink down the size and weight.

Derived from Amptweaker's Pro series, the Tight control and Fat switches were re-configured into a 3-position Fat/Normal/Tight switch to dial in the attack of the notes from thick and heavy to aggressive and chunky. On this model, an EQ switch provides 60's, 70's, or a setting called "Now", which is dialed in for more modern fuzz tones. And there's even a Germanium/Silicon switch to change the output transistor for warmer or brighter/high gain distortion. Amptweaker's popular automatically adjusting bias on the Fuzz controls keeps the sweet spot at hand, and is especially nice for cleaner tones.

All Amptweaker fuzz pedals have a built-in "guitar-style" impedance, which allows you to put any other pedals in front without the traditional issues associated with vintage fuzz pedals. That means it works fine with low impedance active guitar pickups too.

Other features include true bypass switching, 9-18VDC operation, and a thumbscrew-removable bottom plate with special holes to even accommodate tie-wrap or screw-in pedalboard attachment methods. Power supply not included.

FINALLY... a useful Fuzz for Active Pickup aficionados!


Over the last decade or so, I have been on a quest to find the perfect fuzz for my needs, but every one I tried was missing that certain something. I'm a die-hard EMG guy, and so I Googled something like, "Fuzz Pedal Demos with Active Pickup Guitars," and accidentally came across a TDPRI thread that mentioned Amptweaker's "Guitar Style" technology that automatically adjusts the input impedance according to the guitar's output. BRILLIANT! The buffered, low impedance signal from active pickups can be brutal and too much for vintage-style pedals to handle (and still behave correctly, that is), so it makes perfect sense. Upon delivery of the Tight Fuzz Jr. (TFjr), I plugged my Epiphone Les Paul w/ EMG-89s into the TFjr and then into my humble practice rig [a ZT Amps Lunchbox powering a Rivera 2x12 cab]. Straight from the get-go, the TFjr's tones were buttery, beautiful and inspiring, but best of all... they were "useful" tones! Hands down, it's *THE BEST* fuzz I have ever played through, period! In fact, I have a hard time classifying the TFjr as a mere "Fuzz" pedal, for its usefulness and range far exceeds any fuzz I've ever owned or dinked around with. Lemmie put it this way... a good way to tell when a new piece of gear has the "It" factor is when you start dinking around, and then lo and behold 1+ hour later you find you've moved on from wanking thru standard riffs and licks to creating brand new ones--drawing inspiration from this cool, new musical tool. Honestly, I had a hard time making myself *stop* playing. Even when I used the TFjr in conjunction with my Rivera Knucklehead's Rhythm and Lead channels, the unit still performed beautifully without slamming the amp's input and over-fuzzing everything. IOW, the TFjr plays well with others--pedals *and* amps!
