I ordered my new Viper last Saturday. I received it the following Monday. It’s hard to beat that kind of service. Now that I have had it a few days, I thought I would offer some observations on the Burke Viper.
I will add that I got my first low D from Mike Burke in 2000; as I recall it was called the Al Pro low D. It was a great low whistle and had the very handy rotatable low joint for easing the stretch for the right little finger. Since then, I have experimented with some fine low Ds to include Overton, Copeland, and MK. Now I have made full circle and I’m back to Mike’s latest rendition of the Viper Low D. The Viper is in a class by itself. This is not a comparison to other low Ds that I have owned, as they all have their virtues.
The new Viper is another piece of art from Burke. Beautiful fit and finish with an integrated look that is real eye candy. On the one hand, a very futuristic look while at the same time, an almost ancient aura. Let me quote Mike from a recent email; " The earlier tuning slides were a simple square shaped cylinder, and the new ones have a more streamlined profile. The very newest Vipers also have a Delrin lined interior to make it smoother in operation and less likely to stick. Also it has a top slide as opposed to the old ones that had a bottom slide and a breakdown joint below the slide unit to make it easy to transport".
This whistle is a real gem to play. Mike states that the tone holes have a completely new lay out and I can say that playability is absolutely first rate. The action is fast. The tone holes are chamfered making slides and half holing effortless. The tactile feel gives great feedback as to finger placement and fingering feels very natural. The bottom joint is so well done it is hard to see the joint seam and of course this helps the little finger make the stretch. BTW, Mike told me that the bottom joint should not be disassembled for cleaning, it should stay put.
Before I ordered the Viper, I asked Mike if it could honk. I had mentioned that another forum member had written about how great it honks. Oh, yeah, this dog will hunt, er honk. The first thing I did when I put it together was slam a low D and it took awhile to get the smile off my face.
Again, from Mike’s email; why it honks: “The head was completely redesigned to have more backpressure, though I would characterize it as moderate back pressure, you are able to get a tactile feel for the instrument and that makes it a pleasure to play. The lower octave is more powerful and it still retains the clear upper octave. Trying to maximize back pressure is something that I have tried, but it will cause you to give up some power and clarity and therefore I have chosen a middle road on this, producing a whistle that does not leave you gasping but that has a lot of dynamic power in it. Remember that the power must come from somewhere and that means it must come from the player”. I believe that the dynamic power that Mike speaks of promotes dynamic volume, as I can play relatively softly or let it sing and be heard in a crowd. That’s no mean feat and be in tune. BTW, the tuning and intonation are spot on.
This is a very well balanced and efficient low whistle. The combination of the new tone hole placement and the well thought out back pressure gives the player great control of dynamics and tonality. The player has a wonderful palette of sound at hand; this is a very expressive low D. Playability is excellent. I find breath requirement moderate and finger fatigue very low. I have had no problem playing about an hour or so, without a break; partially due to the good ergos and light weight. I will be glad to answer any questions you might have.
The above are my observations after about a week of playing the Viper. As you can probably surmise, I am very happy with this great instrument. I will close with a last quote from Mr. Burke, that shows his typical understatement: “The instrument has evolved over time and I am still tweaking a little, but it is pretty close to what I want in a low D”.
