Ok, so my initial plan was to get a high end, high powered combo amp; i.e. MarkBass or something else intending to add an extension cab later. Then pricing shock occured. So after some research I ended up with Carvin's new BX700 head & their relatively light and portable BR 410 - 4 ohm cabinet. As my daughter would say .. OMG. Right now I'm pushing 500 watts, and when I add another cab (1x15 or 2x10) it will be pushin 700 watts @ 2ohm! I mentioned in another thread this thing BOOMS, PUNCHES & SCREAMS. The tonal options on the head are mind numbing plus Carvin threw in the footswitch that controls the amp's mute and equalizer on/off functions. All this for nearly the same $$ than the combos I was looking at (including the extension cab). I've read complaints of the BX500 reliability in the past but they are seemingly outwieighed 3 to 1 by the positive reiviews. The guys at Carvin told me they've made enhancements to address past quality issues. Hopefully this "new & improved" version will stand the test of time. So far I think this is an incredible value for new gear. Can't wait to add the extension cab!
