To meet the needs of even more players, we asked ourselves if it was possible to maintain the handsome tone of our OTS amplifiers, marry it with a smaller power section, put it in a small package, and then make it even more affordable to our customers. After a few years of experimentation, the answer is “hell yes”. Instead of simply grafting a lower output power amp to one of our current OTS preamp topologies, we started from scratch.  Conversely, it was important to us to maintain true to the OTS series, and what we found worked best is not seen in any of our other amplifiers.

The clean tones are as sweet as any of the OTS series, but the overdrive has more bark and bite to it.  Fear not, fusion noodlers because you can do that too.  But if you want to rock, you will love this amp.  Don’t expect it to sound like our Plexi or Yeti, because it’s not.  But if you’ve wondered what the baby of an OTS, old Tweed Deluxe, and a JTM50 might be…the OTS Lunchbox is pretty close! The OTS Mini 20 is by far the biggest selling amp we've got. Guitar players across the globe have taken a liking to the phenomenal tones for the money spent.

70's Voicing has a more raw OD.

80's Voicing has a smoother OD with a nice singing sustain. Most players choose the 80's voicing.

As with all Ceriatone amplifiers, we’ve obsessed over component selection, and it uses our specially designed, custom transformers for superior reliability, frequency response, and feel.

I wanted to let you know the amp arrived yesterday. Let it warm up, it is very frigid here, and no problems. A great pack job, and the amp is dead quiet at idle, and of course sounds great. I previously had the 50 watt model, which I gigged a ton. There is not an amp on the market that is a better deal than this amp, and that is true of all the Ceriatones. Very pleased with the purchase.

Have a good weekend,

Sam

If you are thinking about ordering this amp then do it! It sounds amazing and is the best value you will find for a hand wired D-style amp period! Nik’s work is amazing! Well worth it! And Scott’s customer service is top notch! Very happy I finally pulled the trigger on this amp!

Scott,
The amp arrived on Friday. I can't believe it got to Illinois so quickly.
The packaging job was excellent and the amp was in perfect condition.

I was able to play the amp for a few hours this weekend.
Your starter guide got me right in the ballpark.
After a few minor adjustments I have it sounding really good.

I really thought that I would have more issues getting it dialed in, but that was not the case.
I don't think it's complicated at all.
I always use my volume and tone controls on my guitars so I think that really helps.
The amp is super touch sensitive which suits my style of play.
I roll off the volume and the amp gets crystal clean.
Roll up the volume and it progressively gets crunchy.

I didn't have any problems getting the balance between the clean and OD channels.
The amp is super musical. I absolutely love this amp.
Thank you for the great service and communication throughout the process.
It was a great experience.
Thanks,
Jan

I ordered the OTS20. I love this amp. The build quality is amazing and the sound is exactly what I was looking for. Nik and his company are top of the line. Scott at Guitar Amps USA is great too. Facebook has a Ceriatone group where Nik the owner is also the admin. You can find out a lot of info in this group about the amps. Nik also answers question in there but he prefers to be emailed at Nik@ceriatone.com for questions. I also ordered a Silver Jubilee 2550 in April so it should be coming soon. I am super excited. Wait times are long but well worth it.

Very pleased with the build quality and the sound of this amp. This little gem performs way outside it's weight class! If you are looking for the Dumble tone in a small package, buy this!
