Petrucci (Awake) and Loomis (Dead Heart) made me crave a 7-string. And that while I was still not having a clue about using just 6 strings to their full potential.

I want another 7 SO bad.

I had an 8-string electric made in 1990 by a local luthier in Wales, with intentions of playing Scriabin's piano music or something very like it on guitar. That never quite materialised, not least because the high A string kept breaking; I was stringing it B-A, like a 6-string with an extra string each side, but whatever gauge I used for the A never lasted more than about 2 days, it drove me crazy. I was getting into death metal at the time, though, especially Obituary and Carcass and other detuned bands; so the low B appealed to me. So I got the guy who made me the 8 to make me a 7-string, very much based on the Washburn MG series - I had an MG-74 at the time - and never looked back. From about 1992 onwards I've played 7-string more than 6-string ...I guess Steve Vai and Trey Azagthoth (Morbid Angel) were the first people who inspired me to learn other players' 7-string parts, 'Passion And Warfare' and 'Covenant' being the first albums where I remember transcribing 7-string guitar stuff.

John Petrucci, and now still John but with addition of Jeff Loomis, Chris Broderick, Fredrik Thordendal, Steve Vai and Devin Townsend

i read through a good portion of the answers here and i didnt see any refference to the 2 bands that got me into 7s. Lord Belial (swedish black metal with lots of death influence) and Emperor (well at least the Prometheus album) i was hearing standard range chords and leads, and then hearing these really low heavy rhythms and was just like "Wtf?! he was just playing a 24th fret high E now they are tuned down to Bolt Thrower and At The Gates range!" and a small search on the interweb led me to seeing that they were using those "silly nu metal guitars" and made me realize there are other possibilities with them. i got a cheap one for a while and got rid of it quick, then i started listening to alot of Meshuggah and Novembre (if you like Opeth, this is a more melodic italian version, with 7s) and that refueled it.still with out one, but im making a down payment on a Sherman weds.

when i had one i tuned standard, Bb, and A.

Vai was the start for me then it just trickled down the line from there anyone that plays a 7 no matter the type of music

[Obscura]

Morbid Angel and Mithras.

Meshuggah, Deftones and Negativa keep me interested. Luc Lemay has a crazy S7 in the Negativa videos.

For me it was first hearing Linchpin by Fear factory and hearing Here to Stay by Korn, at that point I needed to go down to A, as soon as I saw SYL in total guitar with open C and a low G that was it and I wnated the seven right there

Went to guitar center one day, picked up a seven, played the low b, and i said i want one. That simple
