I currently have three Markbass amps:
- 801 Micromark, the single 8-inch speaker combo (45W) that I bought mostly for upright, but now use for about 75% of my gigs (small rooms, coffee house, etc.)
- 802 Minimark, basically a more powerful version of the Micromark (two 8-inch speakers, 150W), with a deeper cabinet that I bought to use with a drummer, because the Micromark was just a little too underpowered
- CMD-121P, their flagship 1x12 300W combo amp, which I use for any big room or outdoor gigs I do
I once had an extension cab hooked up to the CMD-121P for an outdoor gig (500W at 4 ohms through a couple of 1x12 cabs), but it was so loud I had to disconnect it. I've never needed anything bigger than the CMD-121P, but I'm not playing big room "refrigerator" amp type gigs. In fact, the two smaller amps pretty much cover 100% of the gigs that I've played over the past five years. Granted, I'm doing mostly singer-songwriter and acoustic level gigs lately, so this won't apply to people playing in double guitar loud rock bands with Bam Bam on drums.
Obviously, I'm happy they have a variety of amps to choose from.
Sorry to come off as such a fanboy, but they just work for what I need (which admittedly, is fairly modest volume levels with good punchy Precision and upright bass tone).
