I am still digging on my new Ampeg Portaflex PF800 w/PF210HE. It is the Ampeg tonality that I like. So it has got me thinking SVT. I like Blues,Classic Rock and Stax R&B. I am a gear hog. About 40 guitars and basses. And 9 amps. I do have a massive Ashdown ABM EVO 500 w/ 2 410 cabs. I like it and it is awesome,I plan to keep it.Most modern amps seem too HiFi for my tastes. It sounds like an Ashdown but not an SVT. If I get an SVT it will be a tube model and most likely very few excursions out of the house. I see that Ampeg has 3 tube SVTs. And one is made in the USA. I know that the modern amps do not use the same tubes as the vintage. How do the new ones compare ( and which new one to get if I go that way ?) to the Vintage ? And same thing with the 8/10 cabs ? Last but not least shipping. Buying new I get free shipping. Used could be expensive. I am going to wait on buying until after I return to work this summer. So I seek advice from knowledgeable gear guys.
