Hey guys, I've been GASing for a lot but the main thing I have been wanting is a
7 string, I can wait till after college with a well established job before I start buying too much gear to carry

I really want one with a Trem, so I was thinking about getting a used
Rg7620 since they are a reasonable price and not too hard to find.
Just I wanted to ask if there are any other guitars that I don't know about that you would recommend over the 7620 for around the same price.
Also tell me a little about the JP7, I won't buy one as my first 7 but if I love them as much as I think I will I want to know more about other 7's also.
Btw I started playing upright/electric bass before guitar so I figure I'd like 7's a lot since I get low notes almost like an extension on the upright or a 5 string electric.
