  • Rhino Beast Update - NAD!!!

    I forgot to post this here, but I got this a couple of days ago.

    My latest Ebay impulse buy arrived today at work. I hit Buy It Now for this thing purely out of curiosity, and my inherent desire to find bargains in defiance of others' advice. I had heard only negative about Rhino amps in general, but I figured for $199, it would probably be worth it for parts alone, or at the very least, I could re-sell it and recoup my losses easily. However, I was warned that the parts were almost certainly cheap junk, and that I had just wasted my money.




    Upon getting this thing home, opening it up, and taking a look inside, it honestly looks as well made as any mass produced modern amplifier. The trannies are nice big chunks of iron, and look identical in size and shape to the Hammond JCM800 set I recently bought. While the pots and ceramic power tube sockets are board mounted, there doesn't seem to be anything obviously cheap or low quality about this amp. Sure, it's not boutique or mil-spec by any means, but these days, ya gotta spend big bucks for that kind of thing anyway. The one thing that they obviously skimped on (and they're not alone in this respect), is that the chassis is somewhat flimsy. My Slo-Clone chassis is 14 gauge steel with welded corners. This is how an amplifier chassis should be made. The Rhino chassis is 16 gauge steel, which would be fine, except has no welded corners. Without the welded corners, the chassis has a little too much flex IMO.



    Anyway, I plugged in the amp, let it warm up for a minute or so, set all the EQ knobs to noon, the gain and volume right down, and turned it on. Running through a Lopo 2X12 loaded with English made V-30s, I tried the clean channel first, and I gotta say, it's pretty damn good. The BRIGHT and CRUNCH switches, make it very versatile, doing anything from a true clean, all the way up to a nice sparkling AC/DC crunch. This thing is actually very Marshall-like. In other words, it's not super clean, and breaks up quite easily.



    The dirty channel was also a pleasant surprise. Starting at a pretty low gain level, with all the EQs at noon, this amp is pretty much a hot rodded 800 but with some tone stack changes that don't quite hit the mark. Running up through different gain levels, all the way to wide open high gain, it is immediately obvious that it has far too much bottom end for higher volume levels. It seems like they attempted to make a 100 watt Marshall that could be used as a low volume bedroom amp. Pretty silly really. However, having said that, backing off on the low end a little, and adding some mids makes a huge difference. The gain structure is very aggressive, and reminds me a lot of a Fortin Bones I heard recently. It took barely any time at all for me to dial in a useable tone. Curious about how it would take to a boost, I plugged in a Boss SD-1, level cranked, drive at zero, and tone at 9 o'clock. WOW! The nay-sayers aren't going to believe me until I can back it up with a decent clip, but this thing really is a Beast. I was able to cop a convincing Zakk Wylde Blessed Hellride tone. I also briefly tried a Boss EQ in the loop, which is switchable from parallel (with a mix level control), to a series loop. I didn't try the parallel setting, but in series mode, the loop works well with the EQ pedal, and an ISP Decimator noise gate.



    I'm looking forward to playing this at band practice tomorrow, to see how well it sits in the mix.

    The Ebay seller told me there was a problem with the rectifier, and that it wouldn't switch from 50 to 100 watts. As it turns out, it switches between 50 and 100 watts no problem. The only issue the amp has is that it has a switch on the back with 3 sag settings: NONE, MEDIUM, AND HIGH, and the only setting that seems to function, is the NONE setting. I'm not very optimistic about finding a schematic for this amp, but I am going to do my best to track down the problem anyway. If I can't fix it, it's not really a big deal, as the NONE setting sounds great.

    I recently purged myself of a Peavey Windsor that I picked up for around the same price as this, and I was glad to see it go. I bought it on a whim just like with this one, but that was based upon testimony from several people, that they actually sounded pretty good. A couple of years back, I also traded my B-52 AT-100 for a Laney Pro-Tube 50. Again, this was based largely upon the opinion of several people that they did the "hot-rodded Marshall" thing quite well. Both of those amps were a huge, and immediate disappointment. The Windsor sounds gritty and harsh, had tiny, cheapo transformers, and was generally pretty low quality. The Laney was built well enough, but sounded so bad, I took it to a tech immediately, thinking there was a problem. Other than repairing the effects loop (which was still pretty much useless) he said there was nothing at all wrong with it, and that they all sound that bad. I guess he doesn't like them either.

    The bottom line is, barring any future reliability issues (which are an unknown with virtually any amp), I am very much not disappointed with this purchase. I'll do my best to get clips up this weekend.

      You pretty much nailed it on the head with this review. I also got one this week on a trade deal and I love it. A buddy of mine came up and tried it out today and also loved it. I keep forgetting about the sag switch on the back though. I'll have to mess with that. The only difference between my and your amp is that mine is covered with tolex instead of the carpet covering. I mean for the money you can't beat 'em. You can hear some sound clips at www.rhinoamplification.com .

        Cool sound clips!

        I don't like the grey carpet on mine. I wish it was the tolexed version to be honest. However, since I plan on keeping it, I've decided I'm going to re-cover it in grey Mesa style tolex, and make a custom front panel for it.

        After spending a couple of hours playing this thing again tonight, I have to reiterate that this amp really epitomizes the phrase "hot rodded Marshall". I don't think it really excels at modern high gain sounds, at least not without some help. I'm sure with the boost in front, and an EQ in the loop, I could easily get it there though. Since I've been playing a shit-ton of classic and hard rock lately, the Beast fits the bill perfectly. I'll even go so far as to say that it does this kind of stuff better than my Soldano. Don't get me wrong, the Soldano is amazing, and is overall a better amp by far, but it's definitely more comfortable doing smoother high gain type stuff. It's not as aggressive and in-your-face as the Rhino. I haven't managed to find a schematic yet, but I'll keep looking. I'd really like to figure out how to repair the sag switch on mine.

          I'll mess with the sag switch on mine tomorrow and see what it does and how it's supposed to work. I'll let you know the results.

          I wonder if there was a circuit change at all between the carpet covered heads and the tolex covered ones? Reason I ask is that I think mine does high gain really well. It's really tight sounding and get some major chunkage going on. Part of that could be related to the sag switch issue yours has. Plus the last owner fully retubed the one I have with Ruby tubes and also put in 6L6's instead of the stock EL34's. I think these are killer heads. I'm glad you showed some gut shots! I started to take my chasis out to see what was in there but didn't get around to it. If you need any info or part descriptions from my head then just let me know. I'd be glad to help you out.

            I should be more clear. It's not that it doesn't have a lot of gain, because it definitely does. To be honest, I haven't really spent a lot of time with the gain up, messing with the EQ levels. I guess the way I have the EQ set doesn't work as well with the gain up high. I'll have to mess with it some more I think.
            The power tubes certainly could make a difference. Mine has the EL34s, and I believe they are the originals. They are completely blank with no identifying marks whatsoever. I'll probably re-tube it very soon, and mess with the bias a little. It's nice to actually hear from another Beast owner, because these things seem to be kind of rare. What kind of speakers are you running it through?

              I think the only difference between the Beast and the Malmsteen Blackstar is the Blackstar has a build in YJM308 in it. I bet if you throw one out in front you will be good to go.

                I bought one of those a couple years ago. Unfortunately I didn't realize that the polarity on the AC adapter was backwards, and I fried it. I have since replaced the chip, but haven't gotten around to putting it back together. DOD fail for using a non-standard AC polarity, and allowing shit like that to happen.

                  I know what you mean! I just came into mine by chance this week. I had an Ibanez I was trying to sell or trade on craigslist and a guy emailed me and offered to trade me this Rhino head and Laney cab for it. So I took him up on the offer and have been very pleased. Like you though I can't hardly find any information on them. I've been running mine through the Laney cab that came with it which has 4 10" Fane speakers and a 2x12 cab loaded with Celestion G12's. It's cool that we kinda got them at the same time. Did you see the thread I started with the pics of the one I got?

                    Actually I didn't see the thread. I just saw it behind the Westone in the thread you posted about that. Nice score on that by the way.

                    I'm really liking the Rhino a lot. I haven't played it at band practice yet, but I will be very soon. I'm surprised that these amps got so much hate. I've played much worse sounding amps that seem to have somewhat of a following. I had a Peavey Windsor for a while, and that was a complete piece of garbage, yet there seem to be plenty of people over on HCAF who love them. Personally, I'd rather have a decent looking American made 2 channel amp with decent transformers, and plenty of useful features including reverb, than a hideously ugly Chinese made single channel amp, with tiny cheap-ass transformers, no reverb, and really awful sounding gain. Considering I paid the same for both amps, it's a no-brainer. Unfortunately, most of the dudes on HCAF are a bunch of mindless sheep who couldn't form an opinion of their own if their lives depended on it. Their opinions are based solely upon what they have been told by others. There are actually some guys buying Windsors, then spending several hundred bucks having them modded. Talk about trying to make a silk purse from a sow's ear.

                      I used mine today for a gig and it did awesome! I have a push/pull pot on my So Cal Charvel for coil tapping. I used that in conjunction with the clean channel, gain set to around noon with the bright and crunch funtions turned on, for alot of stuff and it just sang. When I activated the dirty channel it cut through the mix really well and sound full and chunky. I plan on keeping the one I have!

                      I haven't messed with the sag switch yet but when I do I'll let you know what it does.

                      I agree with you fully, I don't see why these amps get the "hate" that they do. Seems like a really good quality head in my opinion.

                      Here's the link to the thread I started:

                        These amps get the hate because they were released before all the bugs were worked out. Also.. Malmsteen had several that blew up on him and he stopped using them. He was a major endorsee. On top of that Michael Angelo Batio was an endorsee but he never used them live.
                        I.. personally.. think they got a bad rap and I am happy to see that what I thought all along was true.. they are good solid amps.

                          I hope mine isn't one of the bad ones. It's a pretty damn low serial number, so it has to be an early one. It seems pretty solid so far. There's one thing about them having a bad rep; you can find them dirt cheap, all day long.

                          I just put a set of JJ pre-amp tubes in mine, and it sounds fantastic. The JJs really tighten it up over the Sovteks that were in it. I tried some EH tubes, and they were nice and tight sounding too, but with a little too much sizzle. With the JJs in it, it handles the bottom end a lot better too. I wonder what else I should try tube wise. I might buy a decent set of power tubes for it. There's no telling how old the unbranded tubes are.

                            Check it out.



                            It's actually far from perfect because I just stripped and re-used the original shell. I didn't do a great job of getting all the glue residue off, and the headshell is kinda shitty anyway, so I think I'm gonna make a new one. It will look pretty much exactly the same though.

                              That re-tolex looks pretty good to me. How do you do it? Is it hard? (is there a guide out there, hopefully a video)

                              Sounds like the Rhino is a good deal for $199. I'd hit one at that price. Unfortunately the only one on ebay is twice that. I'll pass.

                              I still disagree with you on the Laney. You must have gotten a bad one, because I have two and the both sound great. And I like the build quality.

                              If you look at the Laney schematic, you can clearly see how they copied Marshall circuits.

                              Also, for diagnosing the "SAG" switch, look for a resistor network being switched in after the rectifier. Sag works better on a Class A amp, and you really need to crank it to tell if the sag is working. It's more of a "feel" thing, and won't really impact the tone much.
