Frequently Asked Questions
It's a good approximation of a classic speaker cabinet, but lacks the flexibility of an IR loader. It’s more than adequate for basic recording and PA applications though.
The monitor output’s re-amp functionality works well for direct recording, though a dedicated re-amp box might offer slightly more headroom and flexibility.
The noiseless buttons help reduce hum, but their effectiveness varies depending on the pickups; high-output pickups will still generate some noise.
