## Overview

The Monoprice 1x8 Guitar Combo Amplifier delivers 20 watts of solid-state power through an 8-inch, 4-ohm speaker, featuring 86dB gain for rich overdrive tones. Equipped with a 3.5mm AUX input for jamming along with MP3s, a headphone output for silent practice, and a line-level output for recording or live mixing, this compact amp is engineered to push volume controls beyond the standard max, making it a versatile and affordable choice for bedroom players and gigging musicians alike.

## Description

Crank it up to 11 using this 20-watt, 1x8 Guitar Combo Amplifier from Monoprice! This guitar amp employs a 20-watt amplifier driving an 8-inch, 4-ohm speaker. It features both a solid clean tone and an overdrive tone with 86dB of gain. It has a line level output, which allows you to send the output to a recorder or mixing board. It also features a 3.5mm AUX IN jack, which allows you to plug in an mp3 player so you can play along to your favorite tunes. The 3.5mm headphone jack disables the speaker when in use, so you can practice in total privacy. Unlike most amps, which top out at 10, this amp has been engineered with volume controls that go to 11! This allows you to crank along at 10 for most of a show then, when you want that extra push over the cliff, you can crank it up to 11 and really send the audience into a frenzy!

Review: Great practice/basement amp for a reasonable price - I've switched over to mostly playing amp-less via amp sim pedals into a DAW + monitors, but still wanted to be able to sit down and quickly start noodling. Monoprice is known for producing decent amps at low prices that over-perform and so I took a chance on this little guy. Glad I did. The amp sounds pretty darn good for the price and you can dial in some nice clean and overdrive tones without the use of pedals. I do have a full pedalboard on the front end, and because the amp takes pedals well, the range of possible tones is pretty wide. Keep in mind that this is an inexpensive solid state amp with a mediocre 8" speaker, so it's not going to sound like a Blues Junior. But I can genuinely say that I am more than satisfied with this amp, and relative to what it cost, I rate it at 5 stars. As mentioned in other posts, there is no onboard reverb; I would suggest buying an inexpensive reverb pedal to go along with the amp (depending on the style of music you play).
Review: Great like everyone says - I bought this based off of all the positive reviews, and ill say so far the first couple of hours have been great . It does have a good sound and everything works great. It was built well , uniform stapling and corner bracing , everything looks great. Ive paid twice as much for comparable amps that looked like they were built on a hungover monday. Sounds like more expensive solid state practice amps with plenty of dirt on the overdrive channel. Loving the 3.5 input for my phone to play some backing tracks to shred on. Perfect for the bedroom or a jam session as long as your bandmates arent trying to drown you out on purpose. If thats the case you need practice in the bedroom some more lol.

### ⭐⭐⭐⭐ Decent practice amp
*by S***N on January 14, 2023*

Arrived in good shape. I was pleasantly surprised at the open back design and good clean sound. The only oddity is that it doesn't work unless power and overdrive are both turned on, this seems to me to be a design flaw.
