to me it dosent matter how brightly a tube glows.......as long as i can hear the difference in sound..its fine...
but i do agree that u get what u pay for....if u are payin' "peanuts" for behringer stuff, dun expect them to work wonders too.....
i've got a behringer mic200 n it works fine, does adds the "tubey" sound to ur tone....but obviously cnot compare to the higher-end stuff that u pay 2 or 3 times more......
