Amptweaker / TIGHTFUZZJR

Based on the classic fuzz sound, this high-resolution fuzz also suits the modern music scene.

The Amptweaker TightFuzz JR is a compact fuzz pedal that can create a wide range of modern fuzz sounds.
The basic sound is a vintage style such as Fuzz Face and Tone Bender. At the same time, it is noiseless, highly resolved, and has modern clarity. By simulating the impedance of a typical guitar in the gain stage, you can achieve fuzz performance in any connection order, just like many modern effects.
The built-in auto bias control ensures a clean and natural tone at all times. By combining an EQ switch with 60s, 70s, and Modern modes, a Tight switch that switches the low end output, and a switch that can switch between germanium and silicon, you can create fuzz sounds with various textures, tones, and gains.

It can be driven not only by 9V but also by 18V. It can also create an open and high headroom sound.

● JR Series
The Amptweaker JR series was born from many requests to create the high-quality sound of an amp tweaker in a small pedal.
It inherits as many of Amptweaker's standard model functions as possible, and also incorporates the experience of the multifunctional Pro series.

Although functions such as the effect loop, LEDs that illuminate the control knobs, and power switches have been reduced, as many tone-related functions as possible have been consolidated into this size.

In particular, the Tight switch that switches the low-end output and the EQ switch that controls the entire EQ both have three modes. By being able to select normal mode and two modes, you can set it to suit your preferences and equipment.

Although it is the same size as many compact effects, the housing is original to Amptweaker. It is a slanted housing that makes it easy to operate the foot switch and prevents you from accidentally stepping on the knob on stage, and the back panel can be removed with a single thumb screw. In other words, no tools such as a screwdriver are required when replacing the battery. The bottom of the back panel is flat, and it is easy to attach the hook-and-loop fastener.
In addition, the back panel has a ""tie-wrap hole"" that can be used to attach the pedal to a pedal board such as a slatted type pedal board with a cable tie, and a ""screw hole"" that can be used to screw the pedal to the pedal board. You can attach only the back panel to the pedal board and remove only the pedal with a thumb screw to replace the battery.
This is a compact pedal made with the player's perspective in mind.
Equipped with a true bypass switch, it can be powered by a 9V battery or a 9-18V adapter. There is a difference in dynamics like a 50W amp at 9V and a 100W amp at 18V.
Controls
・Volume: Adjusts the output volume.
・Tone: Adjusts the output of the high range. You can strengthen the highs or balance them with the lows.
・Fuzz: Adjusts distortion.
・EQ switch: You can set the style of fuzz from the 60s, 70s, and modern.
・Tight switch: Tight creates an aggressive attack, while Fat creates a thicker, more ""buzzy"" distortion.

・Transistor switch: Switches between germanium and silicon transistors.
