yesterday i had the pleasure of using AK's ES5Pro and Alpha Ghost.
i took the opportunity to string two Revelations with the same string (Gosen R4X 110) and tension (24/24) and compared the resulting string job.
i tried to do the same procedure the same. same pattern, same tension (24/24).
the result was a little interesting.
i did the ES5Pro first, i only managed to get the ping frequency of that 30min after. it was 1171Hz. the freshly strung from the Ghost was 1161Hz. immediately there is a slight difference (although AK claims that both machines are calibrated equal using his digital fish scale)
so it appears that there is slightly more tension loss from the get go for the Ghost.
and not only that, we have AK and another very experienced (10+/day) stringer present and both feel (and me) that the ping tail (resonance) of the racket coming from the ES5Pro sounds better, and the one from the Ghost sounds more dead.
18 hours later, the frequency of the one from ES5Pro was 1152Hz, and the ghost one was 1131Hz.
so probably a 30Hz drop from fresh, and un-used. that's around 1lb, which is reasonable.
today the ES5Pro is probably less lively than before though. so maybe the liveliness is from the completely fresh string?
not sure.
thoughts?
