Seems many are constantly on a quest for the perfect tone. I constantly see people flipping amps each year when the new ones hit the market. I made the mistake of not researching before I bought and wanted a nice sounding boutique amp. I went with the Aguilar TH350. Overall I am happy with the purchase. However, I wish the amp had some of the features the new Mesa has. In addition, I wish I would have purchased the TH500. Then I came across someone that used a TH Pedal and a Crown Power amp. That got me thinking about a few questions. 1. Why are rigs with a power amp and preamp pedal not that popular? 2. Why haven't we seen more micro class D power amps like the SWR amplite? Seems like if a small high quality Class D Power amp existed, one could just buy a few preamp pedals and have a wealth of tonal opportunities. Maybe I'm thinking about it wrong. Am I missing something here?
