I've got one in my RG1680, which also has a maple/mahogany body. *Sounds great to me. *Very open but still hot. *I haven't found it to be overly trebly. *Sounds great distorted, nice and crunchy. *Sorry I'm not better with tonal descriptions, just wanted to say I think it sounds great in a
mahogany body. *And as Jimm pointed out, you can always swap it if you don't like it.
