Less pressure, more speed, and plenty of Nymans rosin.
That seems to be the ticket.... although I found that I can bear down on the Gamuts as well, and get a pretty astounding volume level in the process.
It will take some time and finesse, but I blew through a couple of arco solos last night without any major drama. The transition from the Evahs to the Gamuts is pretty seamless on my bass.
