However, if you’re willing to make the investment, you absolutely can’t go wrong with this tone. Being in our number one spot as the best tube amp on the list, you have to expect the price tag on this amp to be a big one. The Ampeg SVT-VR is a reissue of the early 70’s SVT Blue-Line, and it seamlessly blends the legendary SVT sound with modern technology and features. The warm distortion an SVT produces when it’s overdriven is so natural and instantly recognizable, that it will put a smile on any bassist’s face. They’ve been used in countless albums, from classic rock of the early 70’s, to 90’s punk and grunge, and they are still relevant today. My Review: Ampeg’s SVT line of all-tube amplifiers has been a staple of rock music ever since its birth in 1969.
