I hear unwanted hum or buzz. What can I do?

This is usually power or cable related. Start with one guitar, one amp, and two known-working cables. Avoid noisy daisy chains, unstable power supplies or power outlet. If the issue continues, send us a message through the Amazon order page.

My guitar sounds very quiet, muffled, distorted, or has no sound. What should I check?

Check cables. If guitar is in OUTPUT and amp in INPUT, signal is reversed—weak, muffled, or no sound. Correct: Guitar → INPUT, OUTPUT → Amplifier. Ensure 1/4" plugs are fully inserted.

Can the XVI R-13 be paired with high-gain distortion and fuzz pedals?

Yes. The XVI is voiced specifically to harmonize with overdrive and fuzz.

Does the MOD knob adjust modulation rate or depth?

The MOD knob adjusts modulation depth only, adding a chorus-like shimmer to the octave voices. The modulation rate is pre-tuned to an optimal sweet spot.

How well does the XVI perform with an electric bass guitar?

It tracks exceptionally on bass. For optimal response below low G on the E string, use the neck pickup with tone open and play with clean, articulate attacks.
