88 out of 100. Incorporating 250+ ratings and reviews.

Thanks to Bugera, you no longer have to drill a hole in your pocket just to get a good tube amp. The G5 Infinium is a good example, a true to form 5-Watt tube amp head with tone shaping that covers a wide variety of tones, and lets you do so without setting you back too much.

Speaking of tone shaping, the Bugera G5 Infinium comes with a Morph control feature, which lets you shape the voicing to one that mimics American amp tones, and change the voicing to British style amp tones as you rotate the knob.

Volume flexibility is also provided for, thanks to its built-in power attenuator which lets you set the power rating lower, down to 1W and 0.1W.

At the heart of this amp is a single ECC83 preamp tube and one 12BH7 poweramp tube. These are connected to a Class A dual channel amplifier and comes with Bugera’s Infinium technology, which helps prolong the life of the tubes installed.

It also comes with built-in reverb and 3-band EQ.

Response to the Bugera G5 Infinium can be summed up with this statement: It is an excellent amp for the money. Many appreciate its morph feature and the built-in attenuator, which make this amp very versatile in terms of tone and usage. And since it uses tube, reviewers find that it sounds better than other similarly priced amps that use digital components.

Some users are not too fond of the built-in reverb. There are also some who recommend swapping out the default tubes for better tone and performance. With its max 5W rating, this is not meant to cut through a loud rock band on stage.

If you’re looking for a budget friendly, versatile and affordable tube amplifier head, then definitely check out the Bugera G5 Infinium.
