oh and as far as getting recordings of the tones changing from good to bad.
I am all for it. Trust me.
But remember I do work for a living.
Through the day then bids, paperwork or measuring new jobs in the evenings.
Also the KPA has to cooperate.
Maybe there has been a misunderstanding.
The KPA generally stays in a good state or a bad state to some varying degree. But when it works it is excellent. No mistaking it. All in the same rig. I am not basing any of this on changing from one rig to another.
When this first reared its ugly head I actually heard the extreme change while playing. This has never happened before. Or since.
It usually will start up good or bad. The bad has been more prevalent now. The bad can get worse as playing though.
Hope this is better understood.
