I've got a couple EF's that I like?namely the EHX Q-Tron and the Moog LPF/EF. I've made a small travel pedalboard that I'd like to put an envelope filter on, though the real estate is limited. I don't like the Micro Q-Tron. MXR doesn't make the EF for guitar anymore. I'm tempted to try the new MXR Bass EF. Has anyone ever tried a Bass envelope filter with a guitar? If not, any speculation as to whether or not it would sound any good?
