I have a 26.5" guitar and a 25.5" guitar and I honestly can't feel that much of a difference, that is related to the scale, when I play them. The basic difference is that the longer scale has slightly more string tension.
It's been a few years since I've played a Custom 24, but I don't figure I'll be wanting to spend $5-6k for a guitar (that's how much they cost here) unless it's completely custom made to my specs, down to the millimeter. A friend of mine picked one up on his trip to the states, so I'm keen to try it out - though I somehow doubt that model would be ideal for metal. Certainly not with the stock HFS pickup, nor the Full Shred that Mike had his equipped with for years.
ESP LTD EC-1000VB/Duncan, e-guitar, LP-style, mahogany body, mahogany neck (thin U-shape), 628 mm scale, rosewood fretboard, 24 XJ frets, nut width: 42,0 mm, 1x Seymour Duncan JB pickup (bridge), 1x Seymour Duncan ´59 pickup (neck), 3-way toggle, 2x volume, 1x tone, ESP locking tuning machines, Tonepros locking TOM bridge and tailpiece, golden hardware, colour: vintage black
I've got an LTD MHB-400 with a 27" scale length, and honestly it's not a big deal going from a 25.5" or even a 24.75" scale guitar. I expected the extra inch and a half to really trip me up, but it plays much easier than one would think. Sometimes I don't even really notice the extra length.
I've got the exact same guitar here. Stays in tune realy good, grover tuners, ebony fretboard etc. At first I've only noticed the difference to normal scales for a few hours and after I haven't played it for a while. Depends a lot on the size of your hands actualy. If you are blessed with Paul Gilbert'ish hands the transition should be easy. Coolest thing about it is the fact that you can play string diameters and string tension that you are used from your other guitars while playing lower tunings.
Currently mine is stringed with 10-52 and tuned in C. The string tension is almost the same as my "standard" 10-52 in D on a strat-like guitar.
@ERMZ: If you aren't too fixated on the wood of the neck, give the MHB-401 a try at your local store.
