Welcome! Thanks for purchasing your TightFuzz™

Welcome! Thanks for purchasing your

pedal, another Amptweaker™

pedal, the ﬁrst Amptweaker™ handmade product

designed with

desigded with your advice. The TightFuzz is based

on consumersʼ requests for a more tweakable classic

fuzz box, with both Germanium and Silicon transistors.

Automatic biasing extends the range from very clean

tones to killer fuzz using a single Fuzz control. Keep

those ideas coming!

Cool Ideas:

• True Bypass switching–with special input circuitry,

works great with active pickups or wah pedals in front!

• Tight Attack control lets YOU dial in the chunk

• Fuzz, Volume, & Tone with 60ʼs-70ʼs Tone switch

• Bias automatically tracks Fuzz control for greater range

• Germanium/Silicon output transistor switch

• Edge switch smoothes out the buzz

• Pre/Post selectable Effects Loop-tracks Bypass Switch

• Battery On/Off switch with red ʻDonʼt Forgetʼ indicator

• LED lit knobs when using a DC adapter

good tone comes from tweaking ...

Page 2 How does the work? Transistor SW–selects Germanium(warmer) or Tight– set Silicon(brighter/higher gain) output stage transistor higher for aggressive, Fuzz– adjusts Volume– Tone–EQ, chunky distortion, while it a Master adjusts highs attack or automatically Volume, up and down lower for a adjusts bias for set for to balance...
Page 3 TightFuzzʼs On/Off Switch Specs: • Input impedance: 250K Ohm (effect on) • Output Impedance: 1K Ohm (effect on) • Current: 11mA with 9V battery, 22mA with 9V adapter, 45mA with 18V adapter (adapter adds knob LEDs) •...
Page 4 Pre) to tweak the TightFuzz for more distortion and sustain! • Add a clean boost or EQ pedal in the Effects Loop (set to Post) to add more output level or tweak the TightFuzz tone. • By using higher Volume and lower Fuzz settings, the TightFuzz works more like a clean tone(with Tight DOWN, 70ʼs tone) or treble booster(with Tight UP, 60ʼs tone).
