Can any Hellcat VI owner tell me what the string spacing, the bridge width, and/or the tailpiece width is? I definitely intend to get one, but today I had the strange notion of bolting a Bigsby vibrato on it. So I did a bit of comparison via photoshop between the Gretsch Jet Baritone and the Hellcat VI, being that the Gretsch's scale length is a mere 1/4-inch shorter. I did this to see if the Bigsby model B50 would fit on the Hellcat. Unfortunately, it won't (not enough space between the bridge and the end of the bass). But then I remembered the ABS "Les Trem"... The bridge/tailpiece of the Hellcat VI look to be similar to that of a Gibson guitar, and if the dimensions/spacing are the same, then the Les Trem (which has string spacing of 3 1/4") *might* be a viable option for what I have in mind.
The total width from E to E is 2" (center to center). The string to string width is about 7/16". The width of the bridge itself is 3 1/4". The bridge studs are 3 7/8" apart.
It is exactly the same as the TonePros tune-a-matic type bridge on my Schecter C1 Classic guitar, which is the standard Les Paul size. It is a TonePros locking guitar bridge, with the saddle slots widened a little to accommodate the thicker strings.
Hope that helps.
