Artist TweedTone20R 20 Watt Tube Guitar Amplifier Combo

The Artist Tweedtone20R amplifier provides a great vintage-voiced tone at an affordable price. The amp has 2 channels, clean and overdrive. As is typical of vintage amps the 20R has a footswitch jack on the back that allows you to switch between clean and dirty channels seamlessly. The footswitch can be added at small additional cost.

Both channels have independent volume controls that are ultimately controlled by a master volume. This means that you can really drive the clean channel hard to get that nice warm overdrive "breakup" at levels that don't have to necessarily annoy your neighbours. Switching to the overdrive channel provides a thick, creamy overdrive that naturally lends itself to a subtle variety of harmonically rich blues and rock tones.

The 3-band EQ is highly responsive and allows for a vast array of tones to suit your personal preferences.

This amp is loaded with a high-performance Celestion Seventy 80 12 inch speaker for excellent all-around performance and tone.

Absurdly good Amp

Finally got my Tweedtone R20 Amp today and I must say I’m blown away. I was looking for a big rich clean tube tone that could handle the middle position of my Gretsch Electromatic and I’m not disappointed. Beautiful reverb and a drive channel that I’ll explore more deeply later. Price aside, this is a seriously great amp! Thanks to the great team at Artist Guitars.

1 Channel - has onboard FX - still worth it

By: on 18 April 2021
I've owned one of these since 2019 and it's been a very good amplifier. Very recently it's had some noises creep in - probably dry joins and some bad caps - so I cracked it open to see what would need doing (don't do this at home, I'm what you call "a professional"). Well, boy howdy, was I in for a surprise! This is a single channel amplifier with DSP reverb and a weird, 2-stage tubescreamer circuit in front of the input. Each stage of the JRC 4558D has a set of clipping diodes - without disassembly, it looks like some 1N4148 signal diodes on the first stage and a pair of red LEDs on the second. Makes sense when you realise the OpAmp is going to be used for make-up gain since it's only a single-channel amp. Sound is great, even with the weird effects stuff hanging around - should be marketed more accurately, though (not Artist's fault - this is likely straight from the factory)

My TweedTone 20R just arrived and i am in love with it! It sounds INCREDIBLE! Beautiful sparkly clean tones, a drive channel with plenty of punch, and more than enough volume to tick off the neighbours! For this level of quality, at this price point you just can't go wrong. Shipping was super quick (arrived in 2 business days) and as always the crew at Artist Guitars are a pleasure to deal with. A+, 5 stars, 10/10!!

Further to my other post, turns out the whole front grill is held in place by velcro, it pops off, a clever design which makes it quick and easy to get a mic on the speaker. Unfortunately mine has a big overspray of clear glue or paint dribbling down the timber panel above the speaker. If a light hits it on the wrong angle it looks bad but it's only cosmetic. Apart from that I'm enjoying recording with this amp, it gives a solid tube tone!

We are sorry to hear about the cosmetic issues with the amplifier. It is not something that we normally encounter with the amp. Please send us an email to in order for us to assist you in getting this resolved. We have tried to look for the order associated with the email address used to place the order but we are unable to find an order on our system. Thank you and looking forward to your email.

A couple of Problems

By: on 25 February 2021
Firstly one of the screws holding the speaker in place was totally loose ex factory so I had to fix that. Second people should be aware the speaker is at least one inch offset behind the grill. If you want to close mic the speaker at a gig or recording you can't do it easily. Those 57s seem to like being closer to the speaker. I'm contemplating cutting a hole in the grill and fitting a plastic cover thing from a drum shop, drummers use em when cutting into kick drums. Apart from that I like all the controls, these amps are pretty loud and it has a fairly useable valve tone.

Great Amp!

By: on 7 January 2021
This amp is outstanding. Beautiful shimmering cleans, a more than adequate drive channel. It is loud but can be turned down to bedroom level and still sound amazing. I would definitely recommend this little beast. Nice work Artist Guitars.

Artist tweed tone..

Awesome 20 watt tube amp... i own several other amplifiers but since receiving this it has become my number 1... Great amp Great price.. Awesome service overall..

Above & beyond expectations

By: on 9 December 2020
I bought a Tweedtone 20r, which is a great little valve amp for the price, beautiful round clean tone with my Fender & roars on the drive chanel with my Epiphone....but I absolutely must give 5+ stars to the staff at Artist. - Being close to Xmas there was no end of trouble with the courier, but they chased it up on my behalf several times & kept me in the loop the whole way. They were courteous & responsive to my queries & I was never made to feel as if I was a bother. **Awesome Aussie Company ** shop with confidence - JB

One of the Best sounding Combo amps for the money

By: on 2 October 2020
Absolutely a pleasure to play through I have used lots of different brand Amps over the years this one has all the important things you need, I was so impressed with the 1st one I brought another as a backup. For the Money you can't go wrong this is a fantastic Amp with plenty of punch if needed and a great sound all round..

Amazing amp no matter what it costs

By: on 27 March 2020
Too good to be true and I am still shaking my head in disbelief. I am feeling this amp would sound great ran into a 2x12 cab. For the price I paid for this amp brand new I am going to buy another. This amp is gig worthy and can be very loud but sounds great in a band situation. If I had to describe the sound of it then I suppose you could say its a cross between a Vox and Fender, almost Dr Z Carmen Ghia. I would like to try it with a Celestion 2x12 cab.
