Can the R-09 be used in a standard mono pedalboard setup?

Yes. Plug your instrument into INPUT L and run OUTPUT L directly to your amplifier or subsequent pedals for clean mono routing.

What is the difference between Series and Parallel connection modes?

Series mode feeds Channel A's output directly into Channel B for complex cascading modulation, while Parallel mode runs both channels side-by-side.

Does the R-09 include a power adapter?

No, the power adapter is not included. It requires a 9V DC center-negative adapter. No battery compartment—adapter only. Isolated power supply recommended for cleanest performance.

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.

What parameters does the "CONTROL" knob adjust?

The CONTROL knob adjusts an effect-specific parameter for each modulation type. The exact parameter shaped varies depending on the active modulation type.
