James Brown (no, not the Godfather of Soul), the ingenious amp tinkerer, has grabbed the good old Fuzz pedal and combined vintage sound with contemporary technology. As usual with Amptweaker, the Tightfuzz pedal offers a wide range of control options, which make the pedal incredibly flexible. Fuzzpedals often have problems with modern, buffered effect pedals. Vintage fuzz pedals are tuned to the high impedance of a guitar pickup and sound very strange with low impedance signals. Amptweaker has solved the problem by developing a special buffer circuit, which simulates a guitar pickup and is connected to the fuzz circuit. Unusually also the Fuzz Pot: both Fuzz intensity as well as the BIAS of the transistors is simultaneously influenced. The Tightfuzz can easily be integrated into modern pedalboards and delivers a variety of convincing sounds.

TightFuzz

Der Curveball ist ein 3-Band-EQ mit Dual-Boost-Funktionen und kann sogar als Clean-Kanal-Vorverstärker verwendet werden. Die wichtigen Mid-Frequenzen sind per Mid-Schalter wählbar, um 3-Band-passive EQs von klassischen US-Verstärkern, UK-Verstärkern und die Thrash-EQ-Einstellung, perfekt für Metal zu simulieren. Der Mid-Regler boostet den gleichen Frequenzbereich wodurch Cocked Wah Sounds perfekt nachgeahmt werden können. Der Low-Regler boostet wie ein Shelve Filter, cuttet aber in gleicher Weise wie der Tight-Regler ab, so dass du dein Attack weiter optimieren kannst. Der High EQ boostet ebenfalls wie ein Shelve-Filter, cuttet aber wie ein Gitarren-Tone Regler. Somit bietet er dir die größtmögliche Flexibilität für die Optimierung deines Front-End Boosts. Die sekundäre Boost-Funktion ist ein großartiges Feature, um entweder zwei verschiedene Gitarren mit unterschiedlichem Pegel auszugleichen oder zwei verschiedene Boost-Pegel einzustellen. Durch Drücken und Halten des Fußschalters wird der EQ dauerhaft aktiv geschalten und der sekundäre Boost scharf geschalten. Drücke nun den Fußschalter erneut und du bekommst bis zu 10 dB zusätzlichen Boost!

The Curveball is a 3 band EQ with dual Boost functions and can even be used as a clean channel preamp. The all-important Mid frequency is selectable using the Mid switch, to easily simulate 3 band passive EQs from classic US amplifiers, UK amplifiers, and the Thrash EQ setting puts the middle right in the sweet spot for metal. The Mid knob also boosts in a peaky way through that same frequency range, making this a great way to get great parked wah tones by boosting it. The Low knob boosts in a shelving way, but cuts more like a Tight control so you can further optimize the attack. The High EQ also boosts in a shelving way, but rolls off highs like a guitar tone control. This provides the most flexibility in tweaking your front end boost.The secondary boost feature is a great way to either make up for two different guitars or set up two different boost amounts. By pressing and holding the footswitch, the EQ is locked ON, and the secondary boost is primed and ready to go. Press the footswitch again and it gives you up to 10 dB of additional boost

The DepthFinder is an active boost-only EQ pedal that simulates the tube amp Resonance and Presence controls, but without having to be done in the power amp. This means you can use it with an amp that doesn’t have Resonance and Presence, by patching it in the effects loop. It also works great for building a pedalboard direct signal, since that low damping factor is a key ingredient to the overall tone. It can easily make a solid state amp sound and feel more like a tube amp, and can actually widen the bandwidth since it boosts at very low and very high frequencies.

Das TightFuzz Pro verfügt über einen Germanium / Silicon Wahl-Schalter, einen 3-Band-EQ und ganze 3 FX-Loops sowie und einen integrierten Dual Boost mit Octave-Up-Effekt. Als Amptweaker Pro -Pedal basiert das TightFuzz Pro auf dem beliebten TightFuzz-Distortion-Pedal. Sein 3-Band-EQ macht es zu einem der flexibelsten Fuzzes am Markt. Der Amptweaker Tight Regler macht den Unterschied wenn es um das Einstellen des Attacks geht. Die automatische Bias-Funktion, des Fuzz-Reglers macht es möglich, mit nur einem Reglerdreh von den cleansten zu den gemeinsten Fuzz Sounds zu wechseln. Ein wichtiger Unterschied zwischen den TightFuzz Pro und den meisten "Reissue" -Fuzzboxen ist, dass mit dem Tight-Regler vor der Fuzz-Schaltung der Eingang der Fuzz-Schaltung effektiv gepuffert wird. Ein häufiges Problem bei den meisten Fuzz-Designs ist, dass Schaltungen mit niedrigen Ausgangsimpedanzen die Bias- und Gainstruktur vollständig verändern können. Das Ergebnis sind oft ein seltsame Sounds und quietschendes Feedback. Die Pufferung im TightFuzz Pro simuliert die Ausgangsimpedanz einer Gitarre, so dass die Fuzz-Schaltung wie gewollt, und jede nieder-ohmige Schaltung beliebig davor eingeschleift werden kann. Amptweaker-Pedale sind für Effekt-Loops bekannt, und dieses hat gleich 3: einen Universal-Loop, einen, der zusammen mit dem Boost aktiv ist undden beliebten SideTrak-Loop, der aktiviert wird, wenn das Pedal im Bypass ist ... quasi wie eine eingebaute A / B-Box.

The TightFuzz Pro has a Germanium/Silicon switch, 3 band EQ, 3 FX loops and a dual boost with Octave-up effect. As an Amptweaker Pro pedal, the TightFuzz Pro is built from the popular TightFuzz distortion pedal. Its 3 band EQ helps make this one of the most flexible fuzztones available, and Amptweaker's Tight control really makes a difference in controlling the attack of the fuzz. The an auto-bias feature built into the Fuzz control, allows the knob to control from the cleanest to the nastiest distortions with one control. One important difference between the TightFuzz Pro and most 'reissue' fuzz boxes is that with the addition of the Tight control in front of the fuzz circuit, the input of the fuzz circuit is effectively buffered. A common problem with most fuzz designs is that circuits with low output impedances can completely change the bias and gain structure. The result is often an odd sound or squeals, unusual feedback etc. The buffering in the TightFuzz Pro actually simulates the impedance of a guitar, so that the fuzz circuit works in the normal way it's intended, and any low impedance circuit CAN be used in the loop or in front of the pedal. Amptweaker pedals are known for effects loops, and this one has 3: a universal loop, another active with the boost, and our popular SideTrak loop which activates when the pedal is OFF...it's like having a built-in A/B box.

Amp Tweaker are renowned for their brilliant drive pedals. Establishing this reputation is not easy in such a competitive market, and to stay ahead of the game they have introduced a raft of Jr. pedals. Boasting the same amazing tones that we love about Amp Tweaker, these pedals are in a smaller, more pedalboard-friendly enclosure.
All the Essentials:
The Tight Fuzz Jr. takes the essential features of its larger counterparts, ensuring that no tone is sacrificed. The Tight/Normal/Fat switch lets you adjust the attack and response of the fuzz. If you want a thick and heavy fuzz tone then the Fat mode will provide, whereas the Normal mode delivers a full-bodied, chunky sound with plenty of character. Switch to the Tight setting to shelve some low-end, giving you a more aggressive tone that will cut through in busy mixes with a crisp bite.
As Versatile As You’d Ever Want:
A 60’s/70’s/Now switch gves you further tonal options. You can go from a classic Hendrix-style fuzz bark, to a more modern and saturated tone that works as well for rhythm tones as it does for leads. Essentially an EQ switch, you can also adjust your sound using the conventional Tone control, allowing you to brighten the fuzz the higher you crank it up!
A Germanium/Silicon switch gives you the best of both worlds. Often argued by Fuzz junkies, changing these output transistors lets you affect the warmth and top-end of the fuzz, meaning you will have no problem “tweaking” the pedal for the perfect fuzz sound. See what I did there?
Here's what Amp Tweaker say about the Tight Fuzz Jr. Pedal:
With the popularity of Amptweaker's smaller footprint JR series, we're now adding bass and guitar versions of our Fuzz pedals....introducing TightFuzz JR?, Bass TightFuzz JR?, BluesFuzz JR?, and Bass BluesFuzz 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 our 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 the TightFuzz models, an EQ switch provides 60's, 70's, or 'Now' tones, and there's also a Germanium/Silicon switch to change the output transistor for warmer or brighter/high gain distortion. The same automatically adjusted bias on the Fuzz controls keeps the sweet spot at hand, and is especially nice for cleaner tones. And of course the popular Dry Low control is included on the Bass TightFuzz JR.
