A When playing a Crafter guitar equipped with a built-in preamp system through an external amplifier, speaker, or audio interface, following the guidelines below will help maintain optimal sound quality and ensure your instrument remains in good condition for a long time.
1. Cable Connection Order & Preventing Pop Noise
Before playing: Connect the guitar cable first, then turn on the amplifier, mixer, or other output device.
If the amplifier is already on, be sure to switch it off before plugging in the cable.
After playing, turn off the amplifier first, then unplug the cable.
⚠️ Incorrect connection or disconnection order can cause “pop noise,” which may damage the amplifier, speaker, or preamp circuitry.
2. Volume & Gain Settings
Setting volume or gain too high can cause feedback (howling) or sound distortion.
Start with low volume, then gradually increase to find the optimal level for your playing environment.
3. Optimal EQ (Equalizer) Settings
If your preamp or connected equipment has EQ controls, avoid excessively boosting treble or mid frequencies, as these can increase the risk of feedback.
Adjust bass according to the room acoustics and stage conditions, but avoid muddying the sound.
4. Cable Type & Usage — Use TS, Avoid TRS
Crafter’s preamp system uses an active pickup with an unbalanced mono output and supports standard TS (Tip–Sleeve) mono plugs.
The circuit activates and starts consuming battery power as soon as the plug is inserted.
→ After playing, always unplug the cable to prevent unnecessary battery drain.
⚠️ Using a TRS (stereo) cable may cause signal splitting, reduced output, noise interference, or even electrical mismatch that could damage the circuit.
5. Battery Management
Crafter preamps typically use a 9V battery.
Always check the battery level before performances or recording sessions, and replace it if in doubt.
For stable performance, we recommend using alkaline batteries.
6. Preventing Feedback / Howling
Feedback occurs when sound from the speaker re-enters the guitar’s soundhole.
Position the speaker so it does not directly face the front of the guitar.
In large venues or high-volume settings, use a soundhole cover (feedback buster) for effective prevention.
7. Storage & Temperature/Humidity Control
Avoid leaving the guitar in high or low temperatures, or in excessively humid or dry environments for long periods.
Store it in its case, and ideally maintain 45–55% humidity.
???? Tip: Following proper connection steps and sound settings not only protects your sound quality but also prolongs your instrument’s lifespan. The preamp and pickup system are delicate electronic components—by paying attention to your setup and playing environment, you can enjoy stable, beautiful sound for many years.
