I often do fairly quiet gigs where I could get away with not using an amp but would like to hear myself just a bit better so I go amplified. I have a GK MBE150 which is nice but is overkill for these gigs as I barely have the amp turned up at all - just enough so that there is some sound pointing towards me. As portable as the GK is lugging 25lbs in a shoulder bag around NYC gets painful and it would be nice to find something more suitable for the gigs which require just a bit of filling. This has me thinking about a small monitor like Roland's cm-30. I assume something this small would be worthless for bass but I'm curious if anyone has used this or something like it.
