Conclusion

The best tube amp is under 100$—unbeatable price to quality ratio. If you are a beginner, looking for a second practice amp to have fun with, or desire a good-sounding tube amp without busting the budget, this is it… This small wonder will pay itself soon enough through the savings made on buying new batteries and keeping the guitar tone intact. If you are a more experienced player or want to have one of these in your studio, again, this amps is the right choice as well.

This amp is an excellent value for money. Considering the performance, you can’t do much better at this price point, so I’m going to give it a 5/5.

We would recommend this one first while considering buying a cheap tube amp. If you’re looking for something higher-end, then it might be worth going up to the Peavey Valveking range.

What Makes a Good Tube Amp?

Power

The power section of the amp kicks all sorts of butt. It’s made for driving high impedance headphones, so it has quite a bit of power on tap. At 12 watts per channel, it probably won’t have any problems driving most headphones. It’s not going to cause a pair of Sennheiser HD650’s or anything, but for around $100, you’re not going to find much better.

Sensitivity

The amp is surprisingly sensitive, and even the most feeble sources can drive it. I’m driving it off an iPod now, and everything sounds fine.

Noise level

The amp is dead silent, making it perfect for nighttime listening when you don’t want to wake anybody up.

Tubes

Tubes are always a great thing in an amp! They warm things up and give the music some extra life. Plus, they can always be replaced if one goes bad.

Just like all-tube amps, this one has a warm, lush sound. It’s not as sterile and crisp as some solid-state amps I’ve heard, but it still packs plenty of detail. The music sounds lovely and genuine on well-recorded albums (especially classical and jazz). There’s nothing quite like listening to live instruments come to life in your headphones.

The sound can get a bit messy and congested on poorly recorded albums. Things still sound good, but you’ll have to adjust the amp’s tone controls to cut some of the mud out of the music. A little tweaking with these knobs brings out a lot of detail from even mediocre recordings.

Ease of Use

Well, it’s a tube amp. You can’t expect to plug it in and go. It has no safeguard shut-offs, so you have to ensure the volume is completely down before you power it up or switch tubes. Other than that, it’s pretty straightforward.

Build Quality

The amp feels very sturdy and well built. It’s light enough to carry around but heavy enough that you don’t want to throw it across the room. The metal grills and knobs look classy and should stand up well for years of use.

The remote control works well and is a nice touch; however, I wouldn’t recommend using it much. Most people will probably only use the volume control on it, and at that point, you might as well use the knob on the amp. It’s a nice luxury to have, though.

Looks

I think this thing is beautiful! If you like quality, sleek-looking audio equipment (and who doesn’t?), this amp will make a welcome addition to your home system.

Price

You get a lot for only $100. This is the cheapest tube amp I’ve ever seen, and it can’t be beaten in terms of what you get for your money.

Overall, this thing rules! If you’re looking for an amp to sweeten up your sound on a budget, this one will get you where you want to go.
