Thanks Chris B. I'll see how I get on with the weight issue and may have to lighten up later but have gone for the DB212 as I think I'd just compare everything else to it for now.
Graham, you are right!
Thanks for your thoughts gents, so looking forward to getting it into a gig this weekend. I'm not used to new gear, keep the set up I like and stick with it for ages. I enjoyed the PF 500 until it packed in for the 2nd time recently I front of a big crowd! Thankfully the d.i kept going and had in ears for that gig! Must dust of the bassman siverface 50 head, will be interested to hear how it sounds through the DB!
Thanks guys.
