The Green Bullet has a lot of midrange, and tends to feed back a lot.
I've found that a JT30 has a lot more highs, and basically sounds
"pre-distorted" when you tightly hand cup it, and feeds back less than my
I have a feeling you're like me - you like a crunching-dirty overdriven
sound. Unfortunately, the very thing that gives you that sound
(overdrive and limiting) also contributes to feedback.
I use a silver face Fender Champ (6 watts), and have built a very simple
"direct" box (100k 1/2 watt resistor from the speaker to the top of a
100k linear taper pot, and the wiper to a 1/4" jack) and run it through
the PA. Because the PA speakers are further from me than the harp amp, I
can crank it louder with less feedback.
Another hint: get your guitar player(s) to set guitar amp(s) on a chair
or other platform. Have them point the speakers toward their head. Even
the loudest guitarist can be made to reduce volume using this method :-)
(I know - I also play guitar :-)
