Hi, My next bass amp puchase is comming up and I wanted some feed back about a couple of amps. First off any thing good to say about the ampeg pro -6? I currently own a old pro -4 and love it, but I have heard ampeg is not what it used to be. Second, I am considering the ThunderFunk 550. What do you all have to say about it..is it realiable, loud..etc. O Yeah this head will be powering a Bergantino HT 322. Any help would be much appreciated Thanks
