After reading the reviews, I was skeptical about buying the amp. I bought a cheaper used version, and I am amazed by the quality of this amp. It does have a strange smell to it, and no serial number is present on the back of the amp either. It definitely packs a lot of power despite it being short in size. I bought it to replace an amp I had been using, but wanted one with more power. I would highly recommend this amp for someone who wants a good guitar amp that does not want to pay $200-$300 for one with similar wattage.

The sound is clear, and does not produce any noticeable hum as I had seen in other reviews. Well worth the money, if Amazon ever gets the 120 watt version back in stock, I will order that one as well.

Great little amplifier. My wife had an old guitar amplifier that she used for many years to play music for her various fitness classes. I replaced the speaker in it a few times and the speaker went out again recently so I decided to give this a try. So far so good! This amp works great as a small public address speaker, guitar amp or as a music player. I saw other reviews that said to not use it over 1/4 volume but this has not been a problem so far as she uses it regularly at 1/2 to 2/3 volume most of the time.

I played guitar for more than 10 years and tried several amplifiers. For some obscure reason, amplifiers are very expensive. I mean, for what you get at the end, they are really, very very expensive, and If you would like to start playing electric guitar in a band and you are not a neurosurgeon, and would like to actually hear your own guitar over the dam drums, the expensive common brands offer your extreme prices for tiny amplifiers. The ridiculous 10-15 watts amplifiers are almost useless in real life.

Pyle-pro 60 watt amplifier is the perfect starter-amplifier for who wants to be present at gigs with friends and actually hear his own guitar in the middle of the chaos made by the usual overexcited drummer.
The speaker is solid, middle-sized, and powerful; the distortion is not great, but you can buy a $25 distortion/overdrive pedal on amazon and the amplifier will sound better than an overpriced common brands.

Dead On Arrival. BUYER BEWARE!!! As others have stated, which I didn't listen to, there is NO SERIAL NUMBER OR MANUFACTURER'S DATE on these amps. Something's not right. I received the amp in perfect condition. Unpacked it, plugged it in, got a power light, plugged in my Les Paul, got no sound at any volume. No sound even with volume cranked and plugging in and unplugging 1/4" plugs. The amp was dead. I've been playing since 1983. I know what I'm doing and how to use an amp. This is a bad amp in a shady situation considering the lack of serial numbers and manufacturer's dates.

Listen to this review like I didn't listen to others'. Save yourself the time and trouble of having to package the stupid thing back up and take it to a drop off station to return it, then having to wait 2-3 days for a credit AFTER it's been received by Amazon. Amazon is awesome and I think that's perfectly fair on their part. But, if you don't buy it in the first place, you won't have the headache. Trust me. Don't do it. Pick a different amp/company.

Updated 4/17/2015:

I read the reviews before buying this and decided to take a chance. Have messed with it for several days now and can report that various issues in most reviews are accurate, but if used with a good source the amp seems to work quite well. Here's some detail:

1) Hum. Yes - if you drive it from a very high impedance source, it has noticeable hum. But even the Fender Mustang 1 V2 has similar comments from some users. I'm guessing this is at least partly due to how exposed the wiring is in whatever guitar/etc you're using. For source impedances below about 1K Ohm, the hum is virtually gone. For example, I used a midrange Electrovoice mic and it works perfectly. Also worked fine with an electric guitar that had normal (unamped) pickups.

2) Smell. Yes - there was a noticeable smell from the glue/etc when I opened it, but it dissipated quite quickly and I don't find it significant now.

3) Good sound overall. YES. Seems to work nicely as a vocal amp, where the tone controls ("equalizer") do what they should. While it is not a replacement for a good receiver with high-cost speakers for making your ipod louder, it seems more than adequate for a vocal amp. Sounded fine with a guitar as well, but a) I am not a guitarist, and b) it doesn't have the "voices" that competing amps do. So its probably going to come down to a tradeoff - do you want a bit more power, or more refined tone/sound options.

4) Volume. Very good. It claims 60 Watts and my initial measurements suggest this is a reasonably accurate number for the _peak_ output (measured about 2.5A peak into the (assumed) 8 Ohm speaker. Soundwise, it is very loud before it clips, so the speaker in the case is decently efficient too. But as other reviewers noted, this is not enough for some (larger) stage environments. It's a 60 (ish) Watt amp. And no - it is not a class D design. It's a normal linear amp.

5) Fidelity. Good. If you set the bass all the way up and the treble and midrange at about 10 to 20% (close to all the way down), the amp itself is reasonably flat from about 100 Hz to over 20 kHz. But it rolls off a lot below that. 20 Hz signals fed to it appeared to be maybe 20 dB down - and it doesn't sound anything like my home receiver and EPI speakers on music recordings with lots of bass. In its defense - it is a guitar amp...

6) Effects. Has a basic reverb with up to a few hundred ms delay. Acts like a simple one-tap echo, which is fine. Both delay and "depth" adjustments work well. For what its worth, the reverb is implemented with a PT2399 integrated circuit which itself has good specs.

7) Imperfections and oddities. Yes, it has some. The hum is definitely there when the cord is not plugged into a guitar or mic. It might have been less had it been built with a three-prong plug and/or had better shielding. But nothing can prevent hum from a poorly shielded source. It may also squeal some, depending on how exposed the cable is. Kind of weird. I can understand the hum, but squeal is unexpected. But both went away when the source was plugged in (except for normal feedback issue when using a mic of course). The 3-band equalizer controls work reasonably well (especially on vocals), but are pretty strange in that the freq response is not flat at mid setting. The main strangeness though is that if you turn down all three controls, the sound stops! So there's some kind of parallel summing of the frequency bands being done I think, rather than the typical series processing found in entertainment amps.

In summary - the unit I got is loud and worked fine. The sound effects are not as refined or adjustable as something like a Fender amp - but you get somewhat higher wattage here and a reverb that is quite simple and effective. I actually wanted a simple amp and reverb, so I'm happy. (A fun thing to do is adjust the delay while the thing is echoing. It changes the clock frequency in the delay IC and this results in neat sounding frequency shifts :-)

Overall, I think this amp is worth the money. But consider the more refined Fender unit if you don't need 60 Watts and plan to play mostly guitar. For vocals, this one might be better. Personal taste to a large extent seems important in deciding either issue...
