Some models including the CMD combos and the LM3, have stayed in production for many years and probably make up the majority of sales. I consider Markbass to have been the most innovative bass amp manufacturer over the last 15 years. It constantly adds and removes models from its offering but no one should feel pressured to keep replacing theirs as if it were the latest iPhone. A common feature of all Markbass amps is the Markbass own design class D power amps of various output levels.
Even though the LM4 has recently been announced I still prefer the LM3 feature set or the Big Bang if you want to pay the extra for a mute switch and aux in. (I still prefer the LM3 XLR balanced line in on the front panel).
A relatively low risk, low cost entry to the Markbass amp tone is through a second hand LM2 or LM3. Some of the more complicated designs lose a bit of the trademark punchy sound of these earlier models in my experience.
