I did a search and didnt find much info on it. What are the advantages? Disadvanages? What are some good pre and power amps for a rock musician looking for a punchy/powerful tone. I was looking into all tube, and also considering a Schroeder 410 to run it out of. EDIT-I was thinking of a an SVT CL tube preamp, running it to a sansamp rbi for a little grit and such, then I was looking for an tube poweramp. Anyone know of any tube poweramps? I saw some Mono block that was WAYYYYY out of my pricerange. It was 2600. Something a lot less than that and preferably 300 watt.
