Amptweaker Lefebvre TightFuzz
The Lefebvre TightFuzz was tweaked so that setting the knobs straight up matches one of Tim’s favorite settings, which he likes to leave on almost all the time as his main tone…… then cranking the Fuzz is another favorite of his for certain applications where he wants a heavier tone. While most vintage fuzz boxes have very few controls, the Lefebvre TightFuzz includes a Tone control to tame the fuzzy edges and the Tight control, a mainstay of Amptweaker pedals, which varies the pick attack from smooth and thick to tight and aggressive. This is particularly helpful for tweaking a fuzz tone, since many tend to be too flubby on the lowend…..and with the added Dry Low knob, you can tighten up the Fuzz and still blend back in some deep lows. While many modern fuzz boxes have chosen to create wacky over-the-top fuzztone, the Amptweaker approach is to make something that has a lot of flexibile but usable tones.
Tim preferred the Bass TightFuzz set to Germanium output stage, with its softer, lower gain breakup. This cool pedal also has the ability to get lower gain tones easily, with an Auto Bias that adjusts appropriately with the Fuzz control, to get the cleanest and dirtiest distortions possible with one control.
One of the important differences between the Lefebvre TightFuzz 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 from the bass….but in a compensated way. A common problem with the original fuzz designs is that circuits with low output impedances like those in overdrive pedals or from active basses, can completely change the bias and gain structure. The result is often an odd sound or squeals, unusual feedback etc. The buffering in the Lefebvre TightFuzz simulates the impedance of a passive 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. This includes making it work well with active basses and wireless systems.
Standard Amptweaker features include an effects loop with Pre/Post switch to add delay or combine other distortion and EQs to further tweak your fuzztone. Other features include the LED illumination of controls, Battery On/Off switch, and magnetic battery access door.
