I run a couple of rigs depending on size of where we are playing.
Mid/large gigs I run my HD150 with all the built in effects.
Smaller gigs I run my Behringer 2x 12 amp with my Digitech GNX4.
One things nice about the non built in effects like the digitech is I don't need a amp I can run it directly into the soundboards. Most setups for small I run the pedal into the board for a Mains, and use the amp as my personal monitor. Works great.
What worries me is if my HD150 goes out I am screwed.. So I have been bring the backup just in case.
Just wanted to add in a small area you would never be able to crank the 150 up. It really is over killer but hey I am a man over kill is in my DNA..
Do what you think is best for you.
I have been looking at a Pod, and a 6505 + head and some pedals. Love these toys.
