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!
