Can't decide on a micro head. I'll be using it with a CN212 and a 64 Pbass. I don't slap bass just finger pick. MBF800 or TH500. I have been using a WT-400 and a 210xst. I know KJung will chime in because he loves the TH500 and CN212 but I need opinions from others. I tried the Streamliner 900 and didn't care for it. The two amps I suggested are the only two I am interested in. Thanks
