5-Watt, 1x8 Guitar Combo Tube Amplifier with Celestion Speaker
Get superior guitar tone in a small package using this 5-Watt 1x8 Guitar Combo Tube Amplifier with Celestion Speaker from Monoprice!
As the title indicates, this guitar amplifier features a 5-watt tube power amplifier and a Celestion brand speaker. It uses a ECC83/12AX7 preamplification tube and a 6V6GT power tube for the amplifier section, plus a Celestion Super 8 GBA-15 speaker.
The amplifier handles frequencies between 80Hz and 10kHz, with hum and noise -75dB below the rated power and 0.5% total harmonic distortion. It includes a Low input and a High input, with the former attenuating the signal by approximately 50% and the latter being easier to overdrive.

Of Course everyone is going to rave about the price and you will keep on seeing the words "for the price"
Yeah, for the price nothing compares.
It is a tweed Champ style amp that does the classic Champ tone very well. The tweed Champ is the entry level amp that every novice amp builder puts together as their first project. It is also often the first custom built boutique amp that most Mojo tone chasing aficionado's will obtain for their first high-end Boutique amp.
This amp obviously isn't built to the high premium standards of a custom boutique amp or many of the DIY built 5e3 builds. But to most average ears ya almost cant tell a difference. Probably the biggest sonic difference is the speaker and MDF cab. Otherwise this is a great sounding Champ.
Now for the price? There is no way ya can build a complete amp for this price point. The whole reason I bought it for was the fact that I could tinker around and get a single ended output tranny, power tranny, chassis and a cab for a cheap price, not to mention a "Celestion" speaker and Ruby Tubes too? ITS LIKE A WIFE.... YA CANT BEAT IT!
Only problem is that it is ultra quiet and hum free with great tone, I just can't tear it apart to build something else. Too bad the surface mount components dont lend themselves to modification too easily. So instead I have been doing my best to melt this one down. It takes a hard beating and keeps working well. If you need a quiet blues amp for the recording studio give it a try. To gig with, ya need to mike it but will still have trouble loosing it in the monitors. Instead I just hook it up into a Marshall 1960b 412 cab @ 16ohms (impedence mismatch but sounds better than 8 ohms).
I also disconnected the NFB circuit to give it some more growl and looser jangle. It does have nice chime without any icepick! I also have a old RCA Blackplate 6L6GT that I replaced the 6v6 and I am abusing it with! I dont know how or why the wimpy looking iron remains so cool to the touch? I even tried a old shugan 6550 too! (actually got a little bit headroom back with that tube after removing the NFB )
If you like a loose touch sensitive bluesy output tube distortion tweed style tone at bedroom level? Get this amp and remove the NFB and you got boutique sounding champ at ridiculously affordable budget!
PROS: PRICE! Fact that it is a true single ended class A 6v6 amplifier. Pretty tough to kill too.
Nice tone and decently voiced!
Excellent output tube distortion without too much volume!
Great looking and very tasteful styling.
CONS: Small Fake Celestion (licensed by) 8" speaker.
Surface mount components on the printed circuit board for tone stack circuitry.
Too many people will find out about this little secret !
I purchased this thinking it was going to be a Champ clone and it does sound very champ like, but after taking it apart-as i am one to do- i quickly realized this is a reboxed laney cub 8. It says it right on the circuit board and the internals match all the laney cub gut shots I have seen.
But how does it sound? THICK. In all the right ways. With my tele and strat I can get awesome OD tones from noon to 4 o clock on the gain control. They are rich, articulate, and just sound awesome overall. With my p90 LP and tele deluxe the head room plummets but i still get awesome sounding OD with using the HI input.
The tone control has a very smooth and gradual sweep all the way until just before 10. For that last 1/64th of a turn you get a massive increase in the high end, but it is all VERY usable.
I used this amp 100% stock for 1 Praise and Worship gig and it did pretty well. I missed the clarity of my HT 40 as the headroom was lacking, but what do you expect? I then decided to swap out the stock tubes for a JJ6v6s and a JJ ecc83MG in the pre amp and I was able to rock my LP with effects with awesome results at the last PW gig (gain at 1, lo input).
All in all this is an awesome amp. The OD cleans up VERY well with the guitars volume knob and it just sounds awesome on its own. With some new tubes and a 10" speaker you can have a perfectly gig-able amp for almost all genres.
PROS: sweet tones
laney cub 8 at almost half off
CONS: little headroom
PROS: Solid build, 6V6, open back, value
CONS: None yet
Mine had a dent in the front cloth. It was stretched out too much or something. I set my iron to low and wiggled in over it for a second and it went back to being taught and straight. In case that happens to anyone else.
great at all volumes
high and low gain give a little diversity
CONS: not enough of them in stock. Which is a good problem to have.
PROS: Well made and nice to look at.
CONS: It isn't a $100 champ, but it rocks.
PROS: Pros: Delivers tone and versatile given two wattage settings. Takes quality OD pedals, humbuckers, and single coils well. Also, if you like to record with microphones and your only option is a higher watt amp that's too loud., this is an asset. Quality built cabinet. If you have the hands, this puppy translates.
CONS: Cons: None.
I have misused this amp with the wrong tubes and found that I have likely created some damage to the rectifier circuit . The power supply was forced to power a 6550 for daily use for a month before developing some hum . I replaced with a NOS Sylvania 5881 for another 3 months before restoring the original Chinese 6V6. The amp is still functioning and other than some slight hum it is still quieter than the unmodified Fender Champion 600. I have been running it into a 16 ohm mismatched output of my Marshall 1960b cab loaded with greenbacks. I dont know how the output tranny has not smoked but it is still going strong without any hiccups despite mismatched output and wayyy wrong output tube selection. Other than the slight hum from likely abuse and damage caused by running such an extreme tube swap, this amp sounds as good as ever and the reliability continues to amaze me. I have a friend that purchased two more of these and both of his are silent quiet with same consistent good tone. The stock speaker does require alot of break in and is adequate for most average use, however is to the most discerning ear a tad muddy. A better choice is a more tighter efficient speaker such as the various Alnico choices Perhaps a Weber.
I run this amp wide open into 412 cab and it is plenty for most decent blues jams. I cant stress enough the simple "modification" of removing the NFB by simply unplugging the jumper off of the circuit board really gives this amp the perfect sparkly growl and breakup that will yield a nice pleasant and resonant controlled feedback when matched with a PAF Les Paul Humbucker. This amp has one of the greatest authentic tweed champ tones except without the hum and noise. Someday I will straighten out my power supply hum. I keep putting it off until I can get around to research a iron swap out with MM on both the power supply and output. (likely cost twice as much and more than the actual amp) just for giggles and grins comparison!
If you are a tinkerer that is into modifying an amp just to modify it , similarly like the champ 600/epi/blackheart crowd have done,,,, then this isnt going to be the amp for you. First the tone is great just unplug NFB (not really a mod) secondly most of those mod hacks are not going to be savvy enough to source quality tone SMD components let alone the skill to do board level component rework.
Otherwise it is a simple circuit. However it has been built to modern design parameters with proper board topicality and it is the subtle layout and SMD board design that probably this amp owes to its idle ultra quiet demeanor and tonal consistency. The only defective units encountered were a few early shipping units that would howl and oscillate when turned on......... The defect???? That NFB loop plug was keyed backwards and this is how I came to unplug the NFB loop altogether and make this amp rock! the pins on the board were inserted backwards. I was hopeful to find a big surplus of defective units offered for cheap but that never came to materialize!
PROS: Totally a sleeper affordable underground sensational blues amp that has a special Mojo regardless of the price, this has that one unique special tweed like tone across the board at any price point. It is very quiet and hum free for any single ended, this one is the one you can place in the studio.
Very stout and rugged reliability, small lightweight and transportable. This thing can stay in the trunk of the car., bounced around the bed of a truck (dont need to put in the back of truck, because it fits well on the passenger floorboard or back of extended cab) or you can even check it in as carry on luggage. Basically you can take it anywhere and everywhere and not worry about it.... it will always work and if it doesnt you can afford to buy another just in case this one gets ripped off or bashed beyond recognition with no worry of losing that special mojo tone as they all have that same tone stock outta the box.
CONS: I dunno about cons......
Maybe that Monoprice is the only single exclusive source and I am unsure of availability? MAYBE the secret will get out on this little gem and everyone will want one and the laws of supply and demand will drive up the price?
The SMD construction does not lend itself well to the modification hobbyist and tone purist wishing to replace with traditional specialty premium tonal boutique components.( Circuit boards and SMD advanced over PtP for many technical reasons beside financial,,,, get with the times people!)
VOLUME CONTROL? Why ? It doesnt need a volume control as it is always is best used on full wide open, who needs volume control!
Later that week we decided to try going indirect and someone had set up an iso cab with a u47 and guess what else? A Monoprice 5 watt guitar amp!
I now am using two of these in iso cabs for a specific edgy classic rock tone that is similar to a Plexi turned up to 11......
I further took the advice that I read somewhere on here that somebody pulled out the NFB loop wires off the board. I simply unplugged the jumper cable and this works really well.
PROS: Cheap, super quiet, lightweight, small, simple to setup, nails that specific classic rock early plexi tone
CONS: one trick pony, classic but overutilized same old burnout classic rock guitar tone
single mail order source and long backorder to purchase more...
PROS: Lots of bang for the buck.
CONS: Would sound much better with a 10 or 12 inch speaker.
