Contrary to what ignorant people on the internet say, this amp is NOT a clone of the Blackstar Ht20. The latter is a cathode bias amp, thus it has a soft, spongy distortion. But if you play rock, hard rock, hard edged blues and you want a type of sound like Marshall, Orange, Hiwatt, etc, you need a FIXED bias amp, which the G20 is (I have asked a Bugera tech). This bias style will give the exciting, powerful, brutal type of power amp distortion like the amps mentioned above, not the soft and spongy type. Another point about why the Blackstar HT 20 and the G20 could not be more different amps, is that the Blackstar HT has a clean power amp of the clinical type. The Bugera G20 has a ton and a half of power amp distortion when you crank it to max. Lastly, the Blackstar does not feature servo bias (Infinium). You will not find another budget priced amp with servo bias, for you see this type of high tech on a tube amp, only on some amps by Hughes & Kettner, which cost 3 times or more than the Bugera. The servo bias is basically an amp tech into the amp… With FIXED bias amps such as the Bugera, you would have to reset the bias correctly every time you change the tubes. Not only that, you dont even need matched tubes (which costs more than unmatched), for the Infinium will take care of all that. AND, it continually balances the load on the power tubes, which means that if one is more worn than the other, the other one will take some of the load off the worn tube. That means that a set of tubes will last significantly longer, probably several years at least. And preamp tubes usually last forever anyways. So, the only thing in common between the Blackstar HT20 and the Bugera G20 is the COLOUR : Wow. How does the G20 sounds? It will cover ANY main tones as used in pop, blues, jazz, hard rock, and more. Crank it up to full and you will be greeted with impressive power amp distortion. As said, the Blackstar HT series has a clean power amp. One Blackstar I have that HAS a lot of power amp distortion, is the Series One, not the HT Series. I have two of these Bugera amps and bought one as backup but I dont really need it. The build quality is also very good: check out some of the metal film resistors in the pics, as well as ceramic tube sockets (not plastic) and an handle in real leather. In short: if you want a REAL tube amp (not these worthless digital and VST surrogate things), that has servo bias, that costs the same as an indifferent sounding solid state amp, in a portable package, this one certainly fits the bill. Keep in mind that this amp sounds a LOT louder than ANY 20 watts solid state or digital amps. And if you boost the FX loop, it will probably put out close to 40 watts anyways. The amp will be packed properly and will be sent with tracked and insured courier. 20-Watt Class-A Tube Amplifier Head with INFINIUM Tube Life Multiplier, MORPH EQ and Reverb.
