The Monoprice 611705 gives us genuine tube tones in an affordable and practice friendly package. It packs an all-tube 5 watt amplifier with 12AX7 preamp tube and a 6V6GT power tube for authentic old school tones.

On top of that, Monoprice is able to equip this combo amplifier with an 8" speaker, and it's not just any generic speaker, it actually sports a Celestion Super 8 GBA-15. All of this add up to a very impressive value for money, especially given its price tag. Controls are a bit limited with just two knobs that lets you adjust volume and tone, a power switch, and a 50% input attenuation button that behaves like the high / low inputs found on bigger tube amps.

Market response is generally positive, and most of these positive reviews are from users who are surprised to find a good quality yet affordable tube amp. Sound quality gets a lot of thumbs up, with many describing the amp's tube tone as inspiring and fun to practice on. Others also report that it works nicely with pedals, which satisfies even experienced guitarists.


There are some reports of cosmetic inconsistencies, while others feel that the overall build of the amp is not as solid as they would like. There are some who caution that this amp requires a bit more careful handling, but this is expected, given that it is a tube amp.


All in all, the Monoprice 611705 is not only a top notch practice amp, it is also a great entry way into the world of tube amplifiers.
