Update: I just got a Roland AC-60 and love it. I have moved the other two amps into the attic. I had been noticing the CM-30 was sounding a bit like a hornet in a can and this fixed that problem.
It has a kick stand on the bottom to angle it up a bit. But it also has a 1½” speaker mount on the bottom. So for use with a violin I have a tripod speaker stand to get it up off the floor to ear level so I can hear myself.
It weighs about double the CM-30 but it is still “man portable” as they say in the Army.
If this discussion is still alive....
I found the violin always needs a preamp if you are fussy about your sound being really good. I play classical recitals and rock gigs, and I always use the preamp. I use a SansAmp Paradriver with the 3000kHz range dialed out (it has parametric EQ which lets you select a frequency that is too shrill and lower or drop it out). It gives me a warm sound when I want it, and by pushing the bass and treble up to full it adds awesome tone for rock.
Then I run it into anything - guitar amps, PA systems etc - because I have already fixed my sound.
But my personal favourites are the German made HK-Audio PA with a small bass bin and 2 small satellite speakers for when I want a real violin sound or a huge range of tones (especially with a distortion pedal, or an octave pedal set to drop 2 ctaves down), or my Fender Blues Junior all valve combo amp which is a rock amp with real tone.
For FX I use SansAmp GT2 overdrive and amp simulator for creamy warm Mesa Boogie drive to edgy biting Marshall cabinet sounds, and from there a bunch of Electro-Harmonix pedals. I use the POG2 multi octave pedal, Cathedral Reverb, Memory Man delay, Pulsar tremelo, the Q-Tron+, and the Poly Chorus.
The tones are awesome. Have a listen on my page.
Hope that is some help.
