I like the Merrow 7 strings, they have a great feel and play well. I like the hip shot bridge a lot on a 7 and the 26.5 scale, while definitely needing a little time to get used to, really suits the 7 and helps your strings flop around much less. Their sound is fairly specific and some people don’t like how it sounds through their rig (pickups plus the body wood) - it’s aggressive and modern sounding.
The two knocks on the Schecter Merrows would be that (1) the coil tap pot they have in their guitars suck. I’m not sure if they corrected the problem in the newer ones but within a year the pot will start to cut in and out so you’ll need to replace it. I’ve also heard people complain about the switch but I’ve not had any issues with mine.
(2) there will probably be minor cosmetic flaws / imperfections on your guitar related to the finish. Mine had some sort of spray that ended up on the pickups - nothing major but it has what looks to be like flecks of clear coat on the pickups in a couple spots, could also be little droplets of your too - we are talking maybe 4-5 pin-head sizes dots, but some people can’t have things like that on their guitar. For the blue one with the carbon fiber styled binding around the body I’ve seen the line of where it is supposed to end be slightly jagged in some spots and smooth in others. Just random small stuff like that
Another small ding on them would be their brand cases suck and it’s harder to find a good case that works with the longer neck.
Just some thoughts. If you’re buying used getting one of the Merrow schecters is a great deal at 500-700 I think.
