So I've had the Germino Lead55LV for quite a while now and have tried it with a number of different guitars. Here are some semi-coherent thoughts. First, this amp isn't for everyone. This isn't one of those amps that can be described as "flexible" and suitable for every style of music out there. No, the Germino Lead55LV is pure, unapologetic Marshall of the old school variety. It's the old four input design, so there are a lot of tones to be had in there, including the ability to bridge the inputs with a cable to create even more combinations. But in the interest of being clear, all of the tones you will get are classic Marshall tones. If you're looking for the soul-crushing vibe of, say, a Triple Rectifier, you won't find it here because that's not what this amp is about. Apples and oranges. I won't waste time trying to describe the general type of tones the Lead55LV produces, because chances are if you're reading this then you're already a fan of the Marshall flavor and are well familiar with what that sounds like. But just to be a bit more specific, this is plexi territory and not JCM800. In other words, there's an instantly recognizable sizzle and rawness to the top end that has a different overall tone than the later Marshalls. In laymans terms, this amp is great for early AC/DC and perhaps some old school metal, but it won't go into modern metal territory without help. And, no, it doesn't have an effects loop, in case you're wondering. So let's get down to the good stuff. You've been trying different amps looking for the elusive tones from those old cult records of the '70's and want to know, is the Lead55LV the amp to get you there? Well, yes and no. Mostly yes, just as long as you know what you're in for. First, let me start by saying this amp does faithfully reproduce many of the Marshall tones people still love. It does them and it does them well. The problem is, this amp not only replicates all of the good characteristics of those original amps, it also suffers from the same weaknesses. This isn't a new design where Germino attempted to "fix" some of the perceived shortcomings of the old Marshalls by adding more features while trying to maintain the same classic tones. Instead, this amp is really just a high quality recreation of a classic old design, and it makes no apologies for being what it is. There's only one channel here, and there aren't a bunch of switches and toggles to help you tweak the sound in different ways. If you like old Marshall amps, then you'll probably love the Lead55LV and feel right at home. But if you find the lack of a dedicated clean channel annoying, or you don't like playing by messing with the volume on your guitar, then you'll probably find the Lead55LV a tad cumbersome and somewhat one dimensional. But don't judge this amp on what it isn't, judge it on what it is. So what did I mean when I said "yes and no" regarding this amp's ability to get you into old school tones territory. Well, obviously as I've already said this amp can do the thing, meaning it can get you those tones. However, there is a price to be paid if you want to cross the river Styx, and that price is volume. Make no mistake, this amp is LOUD. (By the way, don't mistake the LV in the name for meaning low volume, as that stands for "low voltage." It has to do with the internal voltage and how the amp is setup, not what's going to come out of your speaker cabinet). At half volume, this amp peels the paint right off the walls, and at full power it's no joke. I tried it cracked wide open -- briefly -- and my liver almost died... But do you really need to run it at such outrageous volumes to get the good tones? No. But it is fair to say it starts to lose a lot of its magic when you cut the volumes down to reasonable levels. The rawness of the top end sort of turns into mush and the mids wash out at lower volumes. And it doesn't react the same way to the pick attack, either. But what about the master volume feature, you ask? Yes, this particular model is one of the new Lead55LV's with an integrated master volume on the back panel. But as Greg Germino himself has commented, the MV feature is best used to tame the amp just a little bit and not to cut it down to family-friendly levels. Understand, I'm not a purist when it comes to having to have am amp loud for it to sound good. But in this case, even I am forced to admit the amp just isn't the same when turned down, and unfortunately I found the master volume to be of questionable help in that regard. If you crank the MV too far (i.e. where it actually makes a meaningful difference) it tends to suck the soul right out of the amp. I also found I got some rather nasty, weird harmonics with the master volume cranked down. YMMV. I also ran the amp wide open with an attenuator to see how that worked. The only attenuator I was able to test it with was a Rivera Rockcrusher, and I personally found that was a vast improvement over the amp's own master volume. With the Rockcrusher, I could run the amp wide open and still retain most of the character that makes an amp like the Germino Lead55LV special. There is a lot of debate out there over which attenuators work best with specific types of amps and a lot of differing opinions regarding attenuators in general, so that's really another discussion for another thread. I'll just say I was reasonably happy with the results I got using an attenuator, but not the master volume. You can find more discussion on the volume issue of Germino amps here: Is a Germino too much amp for me? In closing, if you're looking for old school Marshall tones, the Lead55LV will certainly do it. I'm surprised that there aren't more Youtube videos showcasing what this amp can really do. The ones I found generally show the amp being played at lower volumes to produce a nice blusey sound. But make no mistake, turn it up and it will morph into a fire-breathing, rock 'n roll beast . But unless you play in a stadiums on a regular basis, this amp is way too loud to use without an attenuator to tame it. And although I had reasonable success pairing it with an attenuator, if you mostly play at more moderate volumes there may be other options out there better suited to that.
