You see a list of included cabs and stuff. Maybe I don't understand your question?
The cabs are IRs with a little extra, compared to traditional IRs, to make them easier to use.
You can use traditional IRs too, but there are none included.
Yes.
Included cabs are quite good IMHO.
And if you already have IRs you can use them. I don't think I quite understand your question, I'm not sure I reply to the question you really have.
I was just wondering if there were any additional IRs that were freely available from Two Notes or otherwise. But yes the onboard ones are great! Thanks for bearing with me
