Frequently Asked Questions
The cab sims are serviceable for recording or silent practice, but they lack the natural response and depth of a proper speaker cabinet – expect a noticeable difference.
Absolutely! The FX loop is well-implemented and allows you to place time-based effects after the preamp section for a more authentic sound.
The 1-watt mode is surprisingly loud and usable for home practice, providing plenty of gain and character without needing to crank the volume.
