Re: RG1527 reputation
The RG1527 did take the place of the RG7-620.
I have one of each - the two are quite similar all around, and the 7620 really helped to define for me what I personally was looking for in a 7-string.
Of course, the 1527 has the EdgePro7 - decent design, but I'm pretty sure I'd rather have a LoPro7 if I had that choice... but I've got the EP7 working just fine, fluttering well, very nice return-to-zero, etc. so I'm not outright complaining.
Neck construction of the 1527 is technically superior in terms of method, rigidity, and the volute, as opposed to the scarf joint of the 7620.
(I re-profile the neck shapes quite a lot anyway, but I like both as 'platforms' to start from.)
The fret size on the 1527 seems slightly smaller than the 7620 (and, again, no complaint outright, but if I were choosing feature-by-feature, I'd duplicate the giant 7620 fret wire size... =])
Very significant difference; out of the box, the 7620 had, for most people's tastes, far superior pickups, although I found the bridge one was a tad shy of a certain tightness that I look for.
Having said that, I always replace pickups - the bridge one at the very least.
With the 7620, I found that the neck pickup /really/ suits me well, so I have actually sought those out.
So, both my 7620 and 1527 have DiMarzio Blaze Custom bridge plus stock Rg7620 neck pickups. Actually, so does my UV777BK - my UV7BK (black/green) has the Blaze Custom in the bridge, but I haven't changed the neck pickup, as I haven't found a stock 7620 neck pickup in green =] (and don't want to use Toppers to accomplish it).
Over all sound/playability wise - very very similar all around. 1527 is a very nice offspring of the 7620; either would be money well spent if you're debating getting one or the other. Consider the points made above if you might find some little tidbit that tips the scales one way or the other... plus, of course, the 7620s tend to be used, hence tend to cost a tidy bit less.
Hope this helps.
