A game changer!!!
Have you check the Mooer Radar pedal?
It's a very tiny device that can replace your Katana or any other amp's cab.
It comes loaded with 30 cabs including cabs for Bass.
You can choose between 11 different microphones, a power amp section with 4 different types of tubes, plus 3 equalisers to tailor the tone precisely as you want.
Very easy to use interface and software both for Mac and PC where you can save your presets, export and import your own IR's (Impulse Responses)
