I bought this amp head a few months ago and it is now my favorite amp. And it is seriously under priced !! I especially like that I can try out different tubes without having to re-bias everything. I don't know how they work that magic, I just like it. I also like the reverb on this amp. Not too intense, nor tinny. A warm more subtle reverb. I also make full use of the effects loop, where I run an analog delay (and at times some other effects). The amp takes pedals on the front end well, though it has so much gain available you don't really need additional gain pedals. The one pedal I do run on the front is a Boss Blues pedal. I run it on the clean channel, just for some bluesy gain. The clean channel is about as "clean" as you can get with a tube amp. But I'm no expert on clean; I hardly ever play totally clean.
I run this amp to power a 2X15 cabinet with EVM15L speakers. Yeah, originals. This amp absolutely DRIVES them. I mean LOUD. But the bass, middle and treble controls on the amp have great range and I can manipulate the tone quite a bit, especially with a "presence" knob. I play a Fender Strat and a Gibson ES335 through this amp. Two quite different types of guitars and both of them work great with this amp.
I wish, just for the sake of balance, that there was some big negative about this amp, but I heat it up every day and so far so good. I don't really see any bad points. Maybe one small downside is that you can't run this thing on lower volumes and get any gain to speak of. But to me that's to be expected on a 50watt amp. After all, it's not a little 1 watt bedroom amp. (those are cool, too, and I can get gain at low volume on my 15watt Fender SuperChamp head).

regards,
Waddie

I've had my Randall RD50 Diavlo head about a month now and I'm really quite pleased with the purchase of the amp.Build quality looks and feels quite solid,with all the switches,pots and jacks feeling as good as that on much higher priced amps.The built-in fan is relatively quiet and does a great job of keeping the amp/tubes cool.Also,the well voiced 3-band EQ and presence control offer lots of tonal flexibilty.The real surprised was the sweet tones that come from the RD50.While I expected the excellent higher gain sounds,it was the clean,crunch and classic rock/metal tones that really made me smile with satisfaction.Through my Celestion G12K-100 loaded Lopo Large Slant 1-12 cab,the cleans are warm and punchy,with very good harmonic content.In overdrive mode,with the gain at around 10 o'clock,the sound is very much cranked old school Marshall.Kick in the tube driven boost and you're in 80's hair metal land.It's like having a third channel.Crank the gain past noon and you're in modded vintage Marshall territory,with the boost giving the same tone a thick,sustaining layer of harmonic goodness,helping to make leads really stand out.Anything above 3 o'clock is like a boosted/cranked modded Marshall,and maybe into Soldano SLO land with a guitar with hotter/active pickups.

Personally,I love running my Les Paul [57 Classic's] through the unboosted gain channel,set to around 2 o'clock,which gives me great Neal Schon/George Lynch/vintage Steve Lukather like tones.Running a quality delay in the well implemented effects loop adds even more to those classic sounds.My Strat and Tele also sound sweet through the RD50,letting the base nature of each guitar to shine through.Btw,while not a huge reverb guy,the built-in spring unit sounds very good,if maybe a bit subtle.And yes,the Diavlo can get really loud.Also,the excellent master volume allows for some very good bedroom level tones.An all around great job from the guys at Randall.

This is my second Randall and I think it's safe to say I consider them to have THE tone I am looking for. Clean channel is clean, noise-free and full of dynamic range...all the usual descriptors apply, spanky, chimey, sparkly, but turn the clean channel up all the way and kick in the boost and you get a great rhythm/crunch channel that just adds to the flexibility of this amp. Built in spring reverb is very nice...subtle spring all the way up to "surf" territory. The overdrive channel is spectacular and very different from my other Randall while still retaining an open, articulate distortion that seems inherent to "the Randall sound". Push the gain up to noon and bump the mids and you have yet another voicing for rhythm/crunch channel, but with more saturation. The boost button is the secret weapon of this amp...kick it in on whatever sound you have dialed in and things get juicier, meatier and greasier! Run the amp flat out and pull the mids back to taste and you are sure to find whatever metal sound you are looking for. I have a ton of amplifiers and this may be the most versatile of the bunch. As with other Randall products the construction is substantial and the build and component quality is very high for an amp in this range. Randall is one of the few manufacturers that don't skimp on quality tubes in their budget priced gear. They seem to use Ruby 12AX7HG preamp tubes in most of their amps. I have swapped these out of my other Randall and put them right back in because they sounded better than the JJ, Tung Sol, Mullard, etc, that I replaced them with. Same story here...Ruby preamp tubes and a nice set of JJ EL34 are a big part of this amps amazing tone! Yes, this is one of the Mike Fortin modded ones. Sadly, this model seems to be disappearing and has been replaced by a newer Diavlo series, but the new ones are all designed by Mike Fortin and I'm sure sound awesome. If you can find one and the price is right, don't hesitate!
