Are they spring assisted?
Yes Gamma 6004 clamps are spring assisted.
They're said to be similar to when you flip a light switch up or down.
Just to be clear: The clamp bases of the Gamma 6004 are spring assisted.
I believe all clamps on any swivel base whether spring assisted or cone lock are spring assisted to some extent. I really like the feel upon closure of the string that the Gamma has over the Eagnas and Alpha clamps. There is something about the way it closes that it feels nice and firm, yet not damaging to the string. They do feel very smooth.
Good point, Doc..
Gamma 6004 Clamp Bases
To answer the question, yes these are spring loaded.
These bases are copies of the Toyo Zouki clamp bases. The throw on the lever is longer than the Toyo. The internal mechanism drives a wedge into an inverted cone like the original Babolat, but is achieved in a round about way by of a Wire EDM'd linkage.
These same bases were used on the Wilson "Black Matrix" machines at the US Open. These are temporary, as the final version of the bases will be drop release style and the clamps will be tube over post setup.
After 3 weeks of hard use at the US Open the Gamma bases can stick and jam in the locked position. Certainly a surprise to me, but a point of information for users.
In my mind the Gamma clamp base is a poor copy of the original Toyo Zouki design.
I assume you were using the new Wilson machine. What is your opinion of the "Black Matrix", is it a better machine than the Star 5?
Wilson Black Matrix Machine
Is it better than a Star 5? Yes, it doesn't overshoot reference. Prototype clamps are sound, but need to be a lot better to match the Babolat. Frame support is very good, though can block frame holes. Where the Matrix wins hands down is the Ergo-Tilt mechanism. It's the one thing I miss after returning home to string. The machine has a custom height and tilt for installation of mains and a different height and angle for the crosses, all are user settable. Touch screen is very good.
So overall, the Matrix machine has raised the bar. The only question remaining is what will it cost. We will have to wait until January to see.
So there are pluses and minuses in both machines. You have to set your own priorities and choose what is most important for you.
If I could keep the Ergo-Tilt and tension head and use the Babolat frames support and clamps, it would be the best of both worlds.
In Gamma's terminology which type are considered spring action and which are cone lock?
here is info from another post about Gamma's clamps.
not to start an argument but I would have switched the definitions if i was asked this question.
GAMMA has had 4 different swivel clamp bases:
2. Quick Action Bases - spring assisted handle for returning - basically a nut and bolt that tighten to the track. won't ever lock while turning, handle is always in the same orientation when opened on the base. they are on our current table tops, 5003, 5800 & 6500.
4. Switch Action Bases - cone inside, similar to the #3 but improved, there is a spring & cam that lets you know when it is secured, some people describe them to be like a light switch. come with the 6004 & 8800.
#2-4 has springs to help the handle return to the open position, but the spring in #4 also helps to make the closing a lot easier too & there is a cone, so i would consider the cone lock clamps to be the more expensive & the nut & bolt design to be less expensive.
