I'm an old guy. 51yo. I've owned a bunch of Mesa amps over the years. I started with an SOB, then a Studio 22, Mark IIc+, Mark IVa, 2ch Dual Rec, Triaxis/2:90, Lonestar, 3ch Dual Rec, etc. Each time looking for an amp that would do 3 good sounds; clean, crunch and rock/metal. It was tough to do with a single amp, cab and a few pedals. I'm not saying that any of the above didn't have more than one good sound, they did, all I'm saying is you couldn't get it without tweaking for the room, for the day, for the venue, for the house current coming out of the wall, etc. I would have to agree with the comments that have been made that this amp doesn't sound EXACTLY like all of the modes whose names were given of great amps of the past but they sound close enough. The one thing that a lot of guitarists that that state this amp isn't the re-incarnate of the amps of yesteryear are forgetting is that with those amps you had to have only that 'one' sound at a time.
Until recently my amps of choice were a 3ch Dual Rec Voodoo Deluxe mod w/BB Preamp and a Mark III blue strip. The Mark V has retired those great amps from daily use. I won't be getting rid of those amps but the Mark V is my go-to amp for almost any kind of music and it is easier to get close to the sound I want with almost any speaker cab and darn near any volume with very little effort. In fact, if you have learned how to set up a previous Mesa amp quickly, the Mark V is the Anti-Mesa amp, it is so easy to get a great sound with.
I wasn't looking at this amp, I was looking at the Electra Dyne, but not for it's simple layout. The ED is a great sounding amp with what I wanted in an amp, 3 good sounds. I was reading on this forum about some of the differences in the ED and the MkV and then it dawned on me, Mesa is putting the Lonestar clean circuit in all of their new professional level amps. When I bought my Lonestar, I loved the sounds I could get from the first channel, but didn't like the second channels gain sound. My thoughts were this, 'what if the Mark V had the cleans I wanted, the gain of the Electra Dyne in channel two and the third channel could get into the Dual Rec territory? Well in my opinion, that is Exactly what Mesa did. It is quieter, louder, meaner, cleaner, sparkly, growly, all in a good way, better.
This amp has far exceeded my wildest expectations for what an amp from this company could do, and I've been buying their products for 25 years.
Well Done Mesa Engineering and thank you Randall Smith!!!
