Role in the IEM system: Bass sends a clean DI to Front of House for clarity and low-end control, while the bassist monitors the mic’d bass amp for final tone and feel.
Why this works: FOH gets a reliable, noise-free bass signal, and the player hears the full character of their amp, pedals, and cabinet in their IEMs—exactly what’s happening on stage.
Key takeaway: FOH hears clean. The bassist hears finished tone.
