  • Budget amp
Style: Diavlo 100 Watt Head
The clean channel is workable but lets face it most of us by this style amp for rock/metal. Channel 2 with the built in boost is great for rhythm. Channel 3 is high gain and can be pushed more with the built in boost. This is good for solos, live applications, and for being heard in the mix. I boosted channel 2 with a maxon 808x and it works very well I just did not enjoy the maxon. For me the built in boost works fine and doesnt overly do the mids and treble. I will test out with a fortin grind or Tubescreamer and update my review. The amp is very loud and I can get decent tones at low volume. I am running the head through a 2x12 RD V30 cab. I am relatively new to tube amps having played the Blackstar 60w Metal and the Peavey 6505 mini. I prefer the Randall Diavlo over both those amps. The boxing did arrive a little beat up and there are 2 or 3 marks on the head itself. Foot switch works well and I have gotten an hour or two of playing with no issues. Update: Been playing at louder volumes for practice and this amp is very hard to dial in. The sound is very dry and to get good clear gain while boosted, you lose a little tone and sustain. Bedroom volumes the amp sounded great, now in a band situation even boosted is mush and harshness. I have tried a maxon 808x, Ts-9 and fortin grind. It lacks the warmth and tone of a Mesa. ... show more

  • Wow. Very heavy in sound and weight.
Style: Diavlo 100 Watt Head
All 3 channels are amazing. Clean channel 1 is super clean, channel 2 can do rock to metal, channel 3 very high gain and lots of ooomph. Chug city. Wish the footswitch could toggle the effects loop on/off. Built well for made in China. Red LED lights inside are nice touch for the Diavlo / Devil.

  • Worst sounding amp I have ever played
Style: Diavlo 100 Watt Head
Honestly this amp was one of the worst sounding amps I have ever played. It was extremely muddy, you can’t dial in any kind of real sound other than just deep muddy growl. I play a lot of metal and this head should not be called a metal amp. The clean channel was fine and had a lot of headroom so if you wanted to use it as a pedal platform it would be fine in that regard. Channel 2 and 3 are just so bad. I don’t understand the positive reviews saying it sounds amazing... maybe mine was defective because I like I said I have never played anything as bad as this head. I used it in a stereo set up with my DR and I had it running through a V30 2x12... it looked awesome.. sounded like completely garbage. I highly recommend playing one before buying. ... show more

  • and love the way they pair
Style: Diavlo 5 Watt Head
This amp does everything I could hope for, notwithstanding the features I know it does not have. I read reviews claiming its clean tones aren't clean, but with the gain down low, even with high output pickups I get decent enough cleans if I would ever need them. However, that is far from why I bought this little beast. I play it through a Kustom Defender 1x12 cabinet, and love the way they pair, at least for now. I may eventually replace the speaker for better impedance matching, but I have no complaints. My plans for the future with this are to test the XLR output, and to see how the tone can be further shaped with an EQ pedal, and maybe adding a compressor in front and some time-based effects in the loop. I'm also debating maybe a boost before the input to act like a switchable channel, and maybe playing with a few other ideas. I had heard "tube volume" is louder than solid state, and let me tell you: This little guy seems as loud, if not louder, than the 12 watt practice amp I used to use regularly. It's a blast! ... show more

  • Small amp, big grind.
Style: Diavlo 45 Watt Head
This amp is killer. I use to have a Randall Cyclone in my hay day and had to downsize over the years. This little guy certainly has amazing distortion. I have it going through a Randall RG 2x12 cab. It rips and is certainly worthy of gigging. My style is metal and hard rock and it can easily satisfy those genres. If you like really hard hitting grinding distortion, this amp is for you. I have had many amps over the years such as Fender , Mesa Boogie, etc....and to me, nothing compares to Randall. ... show more

  • Do your research
Style: Diavlo 45 Watt Head
Well first off. The reviews and YouTube videos on this were misleading. I received my first head and it worked for 2 days. I then returned and received a replacement. Same exact result. The sound was decent at most. I play heavy metal. And it was not enough gain. I tried boost pedals eq etc.. Regardless it just stopped working. Got a refund. I’ll stick to my line 6 or Marshall’s ... show more

  • Nice amp for the money!
Style: Diavlo 1 Watt Head
This amp is made overseas and quality isn't super-high, but I didn't pay $1000 for it either. It has a loose screw rattling around in it that I had to retrieve and reinstall - not a big deal. The sound is amazing though! I love it! Killer tone without making my ears bleed. Note - it does get plenty loud! I'd buy it again, no question. In fact, I might be in the market for one it's bigger bothers in the future. ... show more

  • Otherwise the sound is good and musical
Style: Diavlo 45 Watt Head
Lotta reviews say this is a high gain amp with lots of gain on tap. Be aware that this is not quite true. The gain is growly and does not saturate. The included Ruby tubes are veeeery trebley especially on the cleans. I'm debating a tube switch, adding an MXR 10 band eq, or just shipping it back. I wanted an all-in-one high gain head and this is not it. To get anywhere near saturated I needed to run the boost at all times. Otherwise the sound is good and musical, just needs a bit of help and I didn't want to run pedals on this rig. I tried this with two different guitars, a stock Jackson late-80's soloist, and my custom OAF 8 string with Blackout pups. Using a Budda 4x10 cabinet, which if anything should have better dispersion at lower volumes than 12" speakers. I've read some reviews saying assembly on these is iffy and to check the tube pins and such. I haven't done that yet. I will give it another run though tonight and check the tubes, then I will have to decide what to do with it. ... show more
