The Mesa Boogie Electadyne is another more recent attempt by the company to capture that stripped down and simple British vibe. It features (shockingly for them) a SINGLE channel with a very basic EQ structure of preamp volume (gain), master volume, bass, middle, treble, and presence. It's got a switch on the far left to switch between 3 different modes. There is a clean mode, a Lo mode (lower gain) and a Hi mode (higher gain). These modes are all footswitchable, so in theory you are still getting some level of versatility by being able to run different levels of gain/saturation at the touch of a footswitch. There is also an onboard reverb with hard bypass if you want a totally dry signal, as well as a switch to toggle between 90w of power and 45w of power. Here's the full list of specs:

Simul-Class Power Amp (Patents 4,532,476 & 4,593,251) featuring a 45/90 Watt Power Switch that incorporates concept elements from our Patented Multi-Watt and Duo-Class technologies (Patent Numbers 7,602,927 & 7,173,488) providing two power and two operating class options: Choose 2 power tubes operating in time-honored Class A/B producing 45 Watts or 4 tubes running in Mesas legendary, Patented Simul-Class Power that blends the best of Class A and Class A/B simultaneously to produce 90 Watts of pure tonal magic / 4x6L6 (or 4xEL-34), 7x12AX7

UTILIZATION

Getting a good tone out of this amp can be a little bit harder than other Mesas by comparison. This may sound strange, as they're normally very complex and hard to dial in anyway. However, I find that when I'm limited by a single set of EQ and gain controls and am trying to footswitch between different levels of gain that it can be a sheer impossibility at times. The biggest caveat I had when setting up the amp initially was trying to balance the gain level between all three modes. I prefer a very pristine and low-gain clean tone. However, in order to get this, the preamp volume had to be lower, and as a result the Lo and especially the Hi modes didn't have near enough raunch for what I wanted. Conversely, to get the amount of saturation I wanted on the gain modes, I had to dime the preamp volume which caused the cleans to be too broken up for my general liking. I ended up simply using the Hi mode with full preamp gain and just rolling down my guitar's volume when I needed cleaner sounds...

SOUNDS

I've tried this amp with various Gibson, Fender and EBMM guitars. It's definitely got a lot of that classic British flavour on tap and sounds decidedly like a hot rod Marshall with a bit more of that atypical refined Mesa thing going on. The clean mode, when set for a more pristine clean sound, has that spanky and slightly scooped out hollow clean tone that reminds me a lot of an old Marshall JMP. It's got a bit more warmth a-la Fender, but it still is a very UK clean tone. The Lo mode basically sounds like a Marshall JMP head that's running full tilt to my ears, but with smoothed out highs and a slight bit more compression. The Hi mode takes things up one notch to be like a hot rodded Jose or Cameron modded JMP/JCM800. It has that really great set of even harmonics and overtones as well as that biting top end, but it never loses definition or muddies out at higher volumes. Very cool! I like the Hi mode a lot because it really does a good job at giving the storied Marshall hot rod tones, but STILL whilst retaining the feel of a Mesa amp.

OVERALL OPINION

All in all I think the Mesa Boogie Electra Dyne is a very admirable amp from the company. It's certainly a departure from their feature-ladden Rectifiers and Mark Series amps but it sounds every bit as good. Because of the single channel, it can be a bit more difficult to really dial in the sounds to go from clean to mean but if you compromise a bit on both ends you can make it work. At $1,800 new I'd say this amp is priced a bit on the high side for what you're getting, but they can be had for a fair bit less than that used if you look. If you like Marshall but want a Mesa, give this a go.
