I am trying to get a sense of how an A2 is different than an A5, tone wise - for example, if I had an A2 and an A5, each with the same wind and same wire, am I right to expect that the A2 would be darker sounding, while the A5 would be hotter? Is one more prone to producing the "quack" in 2 & 4? If this has been beat to death already in another thread, let me know and I will check it out - thanks very much!
