I have had a CMD 102P for quite a while now and I like it a lot.
I wanted something lightweight & fairly "transparent" that would allow my bass to sound pretty much like it does through my cafe walter headphone amp... and for a single-unit/all-in-one combo, the CMD 102P is pretty darn close.
I can just plug my bass into it and play - I don't use any EQ on the combo or on my active fretless instrument.
Basically, my bass... only louder.
And it fits nicely onto the passenger seat of my Toyota pickup.
I would've definitely considered a CMD 121H if G.C. had had one when I was shopping, mainly due to the fact that it has the compression driver w. the custom horn, rather than a piezo tweeter like the CMD 102P - but they weren't yet available in the U.S. at that time...
No regrets: they'd have to yank the CMD 102P from my cold, dead mitts to get it away from me!
