Greetings all, This is my 1st. post. Glad to be here. Thank you for having such good advice. My question is I have a Marshall dual mono bloc a 9100 to be exact. I also have a Carvin V-3 head. I feel relatively safe in using the line in/line out and daisy chaining the two strickly for power. I would be going directly into a Rack eleven preamp But just in case I may be wrong. I appreciate the time. Cheers!
