Setup
Battery Installation

The amPlug3 Tone Hammer requires 2 AAA batteries for operation. To install, slide open the battery compartment cover on the back of the unit. Insert the batteries, ensuring correct polarity as indicated inside the compartment, then close the cover securely.
Connecting to Your Instrument

The amPlug3 features a 1/4-inch plug with five adjustable positions to accommodate various bass guitar input jack orientations. Insert the plug firmly into your bass guitar's output jack. Adjust the plug's angle as needed for a secure and comfortable fit.
Connecting Headphones and Aux Input

Connect your headphones to the dedicated headphone jack (3.5mm) on the amPlug3. For practicing along with backing tracks or external audio, connect an external audio source (like a smartphone or music player) to the AUX input (3.5mm) using a stereo audio cable.
Operating Instructions
Controls Overview

The amPlug3 Tone Hammer features three main control wheels on the top surface, along with side buttons for power and effects/rhythm selection:
| Control | Function |
|---|---|
| Gain | Adjusts the input level from your bass guitar. Turn clockwise to increase gain, counter-clockwise to decrease. |
| Tone (Tilt EQ) | Shapes your sound by balancing low and high frequencies. Turning the knob adjusts the overall tonal character, boosting lows while cutting highs, or vice-versa. |
| Master Volume | Controls the overall output volume to your headphones. |
| Power Button | Press and hold to turn the unit on or off. |
| FX/Rhythm Button | Cycles through onboard effects and activates the drum machine. |
Dual Analog Channels
The amPlug3 offers two distinct analog channels, indicated by the color of the LED on the unit:
- Clean Channel: Provides a warm, dynamic, and uncolored bass tone. (Indicated by a green LED)
- Drive Channel: Delivers a rich, overdriven sound inspired by the Tone Hammer amplifier series. (Indicated by a red LED)
Switch between channels by pressing the dedicated button on the side of the unit.
Onboard Effects
Enhance your sound with three built-in effects, accessible via the FX/Rhythm button:
- Compressor: Modeled after the Aguilar TLC Compressor, this effect helps to balance dynamics and enhance clarity, providing a more consistent sound.
- Reverb: A room-style reverb adds subtle space and warmth to your tone, simulating acoustic environments.
- Chorus: Inspired by Aguilar's Chorusaurus pedal, this effect adds dimension and motion to your sound, creating a lush, swirling texture.
Press the FX/Rhythm button repeatedly to cycle through the effects. The specific effect engaged may be indicated by a combination of LED flashes or by listening to the sound.
Built-in Drum Machine
The amPlug3 includes built-in rhythm patterns with adjustable tempo, providing a versatile backbeat for practice and songwriting. To activate the drum machine, press the FX/Rhythm button until a drum pattern begins. Use the Tap button on the side to adjust the tempo of the drum beats.
Direct Recording
The amPlug3 Tone Hammer can be used for direct recording. Connect a TRRS cable from the amPlug3's AUX input/output jack to your recording setup, such as a smartphone or audio interface. This allows for high-quality direct recording of your bass tone with all the amPlug3's features.
Maintenance
- Clean the unit with a soft, dry cloth. Avoid abrasive cleaners, solvents, or harsh chemicals.
- Remove batteries if the unit will not be used for an extended period (e.g., more than a month) to prevent battery leakage and potential damage.
- Store the amPlug3 in a cool, dry place away from direct sunlight, high humidity, and extreme temperatures.
- Avoid dropping the unit or subjecting it to strong impacts.
Troubleshooting
