Boy how things have changed...
I remember the days when we opened the box, spent an hour on the board and headed for the gig.

Most detriments are found on the job, where they always show up

We would set up our go to sounds, easy eight styles, and our control pedals.....and do our thing on the job.

The pa4x is similar enough to the pa900, you have played for two years....it would have been a piece of cake to perform, the day you got it..
The audience would never be aware of the things you worry about, and you would learn much more from experience.

We are not talking about style composing, sampling etc...we are talking about what you always done..comping yourself while singing..
