I'm buying my first decent amp for home practice and stage monitor (I have PA support). I would like to buy something that I won't be looking back in 6 months saying I should have spent the extra and gotten.... So, I'm thinking Markbass mini CMD 121P or Carvin MB12. Both can take an external cabinet if plans change. Carvin: doesn't have effects loop Markbass: doesn't have built in compressor (may have to add a pedal) and it's twice the price Is the Carvin close? What else am I missing? Can anyone compare the thump and tone? I've played the Markbass several times at GC. Thanks!
