Start by matching your device (iOS or Android) and your primary use to the irig interface black lineup. If you mainly need to plug a guitar or bass, pick a model designed for instrument input; for general line or mic work, choose a more versatile option. For simple, portable needs, iRig Simple or iRig Mobile are good starting points, while the iRig Guitar Interface suits guitar-specific setups, and iRig Universal or iRig Digital Interface offer broader compatibility. This approach keeps your workflow smooth across practice, recording, and streaming with the iRig family.
