Are there any frequencies that more often tend to cause feedback than others? Which frequencies would that be? I noticed that maybe those: 1kHz, 6,3kHz, 1,25kHz, 250 Hz… ? Your experiences?

There is some math with 250Hz and 1KHz: If 250 is a problem, check 500, then 1K. In this case 250 is the Fundamental Frequency and its upper harmonics may be causing problems too. 250 X 2 = 500 x 2 = 1K (Times 2). Also good to check 250 x 3 = 750 to see if theres any problem there.

DO NOT blindly follow this suggestion!! Using math is just a place to start, but it can help you get things rung out quickly with less trial and errors.
