The Vox AC4TVH, however, is designed to solve the problem, When you're practicing - or recording - with your high-wattage all-tube amplifier, it's simply hard to achieve those classic tube tones at listening levels. Already a 4-watt amp, the Vox AC4TVH gives you incredible tone when you need to crank it to reasonable levels. But, for tremendous tone at really manageable levels, you can use its built-in power attenuator to take it from four watts down to just one watt, then down to just 1/4" watt. It's the perfect partner for late night recording sessions, when you don't want to wake up the neighbors. Its a good amplifier for playing rock, metal songs. I really enjoyed a lot playing heavy metal riff n leads on it ..m it has crisp clear sound quality even in higher gain. The amp has great durability too... I m using it more 7 months got no problem with it..even no noisy sound .
