It's pricey but a Phil Jones Double 4 will definitely allow you to jam with guitars and a light-handed drummer IME. The Markbass Micromark 8" version will do the same.....not sure if the 6" would cut it. The double 4 fits easily into a regulation carry on bag; that's why I got one.
Some of my heroes: Jean Beliveau, Richard Dawkins, Galileo, Hubert Reeves.....
