At the risk of sounding stupid I am going to ask anyway.
What are the advantages of getting a separate head and cab over a combo?
As I am in the process of saving up to get one or the other, namely the Boogie Express 5:25+. The head is £1299, but the combo is £1399 with a 12" speaker. Meaning I get a cab for £100 more, to me that is great value and I wouldn't think Boogie make bad speakers, I believe they are Celesion speakers built to Boogie spec.
The advantages that I can see are, more flexibility, especially for gigs if the venue has a cab or take to a friend's.
Weight, you can split it up so it is lighter to carry.
You can combine it with a cab of your choice down the line.
Would that be pretty much it?
Second question, is there any amp in the PRS line up that does a similar job to what the Boogie does, offering 2 or 3 different wattage in the same head unit.
