Just buy it

Just buy one. Best amp I own. Immediately selling my boss katana and my artist cremetone after playing this thing. Sounds average on its own but with pedals it is the best thing I've ever owned.

Joyo JTA05 - Get One of These.

By: on 1 June 2021
Bought this from Artist Guitars via ebay. No dramas, thanks again, Artist. Anyway, internet banter tells us this amp is the same as the 50's Fender Champ circuit - for real. It has a Celestion speaker as standard and some modders have gone back to it after trying substitutes. So how does it sound? Really good! I have done a side by side comparison with another 5watt 8" Celestion loaded amp, that shall remain anonymous, and it kicked butt. The other amp was good but the Joyo was fatter. I also played at lower volume at a friends house, with a nice delay in front of the amp and no break up - very pleasing. Humbuckers and singles sound good but this becomes subjective. I tried both and I'm happy. There is one mod that may be worth doing - copied from "Add a 25uF/25v bypass capacitor across the 1K5 cathode resistor on V1 (first triode). This cap adds grit and gain. It is not shown on the original 5f1 schematic but is apparently present on most vintage champs." This mod should brighten the sound somewhat however you might think this unnecessary and the sound straight out of the box is pretty fat and lovely, just not terribly bright, which could be a good thing for lower volume settings. This amp is a steal for the price. Just get one.

Thank you so much for taking the time to leave this nice review. I also sent an email regarding the star rating just to see if this was by mistake.

A great sounding amp!

This amp is exactly what I needed. If you are looking for a small amp with a great sound then consider the Joyo JTA05. The review from a previous customer listing the pedals he used with it was very helpful in my decision making. I have a Big Muff, Fuzz Face, Tube Screamer, and Vox Wah, among others, and they all sound fantastic through this amp. Yes there are no onboard effects on the amp, nor aux input, but the high quality, warm tube sound more than makes up for it. There are 2 inputs so what I have done is use input 2 as an aux input when required. i.e. I use a 1/8" to 1/4" converter and play music from my phone into that input and jam along to it. Just be mindful to change your playback settings to mono when doing this or you will only hear half the mix of whatever song you're playing. There are also 2 speaker outputs for 4 or 8 ohms. I played it through a Marshall 4 x 12 cabinet for curiosity and man it sounded big! It did get fairly hot after half an hour through the cabinet but I guess a 5w combo is not designed to be played through a 4 x 12 cabinet. At some stage I will take the advice of other reviewers and upgrade the tubes, but for the moment it sounds fine as it is. I'm also looking forward to hearing how the 8" Celestion speaker will sound once it's broken in. New speakers usually take 20 to 30 hours of playing time to run in and then tend to sound better. So this great sounding speaker should sound even better soon! If you are considering this amp, just buy it. You won't regret it.

O Joy

I've now had one of these amps for two months. I practiced through a valve 'gramophone' when I was young, and liked the soft clipping it produced, but have no recent experience of other valve amps. Present day comparisons are to a V-Amp through some P.A. speakers, and a Fender G-Dec modelling amp - both model some nice tweed / class A sounds, and can add delay effects and EQ unlike the Sweet Baby. Neither of them has the tone or immediacy of response of this little amp though. It gives a feeling that you are hearing what your fingers are doing (right or wrong!) in real time, almost as if you can hear your fingerprints brushing across the string windings. From Tele twang to humbucker oomph, there's always a musicality, and any breakup when you drive the amp feels tonal rather than harsh. It has plenty of volume for home use and if you are a serious learner thinking of buying a solid state practice amp, I'd say this is well worth the extra coin, and the responsiveness is likely to help improve the dynamics of your playing. I don't gig on guitar (sax player) and if I did I'd probably look into which pedals complement the basic tone, but it's lovely as is. My only regret is the couple of months I told myself I didn't need to buy one - wish I'd got it sooner.

Joyo JTA05 5W Class-A All Tube Guitar Amplifier

By: on 2 March 2021
How they can make and sell these things for the price is beyond me. The sum total for the parts alone is way in excess of the asking price and the build quality is excellent. I have top end amps as well (Brit Vox AC30, Fender Tweed Bandmaster, etc) and this little lady can hold her head up high. It's a ton of fun and sounds the business with any guitar be it single coil or humbucker and you won't miss any tone control 'cos the tone is perfect as is. Whack a decent set of valves in it and it is stunning and it's still cost you stuff all. There's no excuse not to have a decent tube amp when you can get one of these for the price. It's cheaper than a decent pedal! And buy it from Artist Guitars, their service and pricing is excellent. Happy I am.

Warm sounding, simple to use!

By: on 23 December 2020
With just a single volume knob, there isn’t much you need to do to get this thing sounding great. Keep it below 3 (out of 12) on the dial and it’s warm and clean, past 3 out of 12 and it gets both a loud and gritty. Keep turning the knob and it gets dirtier and dirtier. With humbuckers it really snarls - great for blues or Rock’n’Roll. I’ve run a few different pedals in front and they all work really well - couple of big muffs, delays, chorus, fox tone machine, fuzz face, super fuzz, muff fuzz, tone bender (I love fuzz pedals and this amp works well with them all!), and at lower volumes an overdrive works wonders. I think it’s the best practice amp I’ve ever had. And even though it doesn’t have a bunch of third rate fx built in its sound is so good you’ll quickly realise you don’t need 1001 amp/cab emulators - just a great responsive WARM tone with plenty of volume for home practice, recording or jamming with others. I did swap the stock preamp tube with a few different ones I had here, and settled on a tung sol. It also has speaker out jack, and sounded great through a 112. (I was actually planning on building a 5f1amp (which this is a clone of), but the parts alone cost 3x or more what this thing does - just the power and output transformers here in n aus will set you back more than this thing is new - add a speaker, jacks, knob, pot, turret board & components and you looking at the better part of a grand. Granted, this thing has a couple of pcb’s inside and is mass produced in China, but it sounds fine (my plan was to actually gut it, keep the speaker and transformers and re build it, but it sounds great so I’m keeping it as is for now - BEWARE valve amps can keep lethal voltages in the circuits even when switched off - don’t tinker if you don’t know what’s what!)

A new standard at a price musicians can afford

By: on 1 September 2020
I've been a professional musician for 40 years and this is the best deal I've ever seen in a REAL guitar amp. You get a massive valve amp tone , form clean , breaking up all the way through to Marshall-type overdrive, and the sound is not lacking in any way. 5 watts is plenty for home use, but louder than you might think, and the price is half the amount that it would cost to buy a kit to make the same amp your self. To be honest, I'm now eyeing off the 20 watt-er , for the odd gig or 2. Great work Joyo .

Still Going Strong

This is probably the best Champ-Alike on the market. For practice, nothing at this price-point will deliver the same sound and tube feel. Great for technique practice, anything clean (country, jazz, etc) right up to some reasonably heavy stuff - think Led Zep at low volume (almost ;) ) It's rugged and the PCB is mostly (if not entirely) through-hole so you can fix anything that goes wrong. If you're into modding or building, this guy is an unbeatable source of donor parts and chassis/cab/speaker, etc ...
