ok, ive heard that some say if you adjust the BOV correctly that it will eliminate the stalling issue, is that true or is the dual port the only way? Quote
no matter what you do to adjust the BOV you will still have to stalling problem. i would recomend a dualport one, because if you do get sick of the sound that it makes you can very simply pull the trumpet off the BOV and cover the port with the backing plate.
