on all of my basses, I use GHS strings. on all of my guitars, I use d'addario with amps, pickups, guitar, and string technology advancing, it dawned on me that maybe it was time for the guitar to change in a way that made it possible to take advantage of some of those technologies. Consider downtuning, for example. Many years ago, some of the guitar pioneers made the determination that guitars and amps were capable of producing lower frequencies than those that were being used at the time. But how low can we go!!! Today, we are blessed. A few years ago, 7 string guitars were all the rage. For whatever reason, they are not very popular right now, and this is to our advantage. As far as I'm concerned, the more strings it has, the better. I was able to buy several very good guitars off of Ebay for just a little over $100. Now I was in a position to do some serious experimenting. My guitar signal is basically split into two signals using a rack mount mixer. One of the splits goes through the POD, and becomes my "clean" channel. The other split goes through the triaxis and into the Mark III head. My bass rig is basically just the SWR When it comes to guitar, I like the chording and scale patterns that a standard guitar tuning presents. But I always wondered what the instrument would sound like if I changed the pitch of all the strings equally. Not just detuning the low string, but detuning the entire guitar. Likewise, a 7 string guitar is an interesting instrument to play when you raise the frequency of all of the strings. When you are playing through a boogie rig like mine, and you have it turned way up, the guitar becomes a whole different instrument. The basic problem with alternate tunings is that the guitar is begging for you to change the string gauges. If you try to tune a string too high, the string ends up being too tight. Even without the obvious problem of breaking it, when it's too tight, it's hard to get the kind of vibrato that you want, and the harmonics tend to disappear. Also, you might notice that the volume level of the string drops off. When you detune a string, it ends up being too loose. This makes it hard to control. Again, you tend to lose the vibrato and harmonics, and the string will buzz and flap around. The worst part about detuning is that the string will appear to be louder than the rest of the strings. This is a big problem when you are trying to play complex chords. Ideally, we would like to get the gauges in some manner of order so that each string is equally tight. That way the volume levels of each individual string is consistant, and you get good control and harmonics. I have been doing some experimenting with gauges on my various guitars. I don't have it down yet, but I'm getting close. You'll notice that the gauges are a bit heavy. When I'm playing a regular old six string, if the guitar is capable of handling it, I will string it with 13's on top. That's right .... 13's. Yeah .... I know, that's way out there. It definately takes some getting used to. Maybe you have to have strong hands. I don't know. All I know is that it's worth it when you get that kind of tone. You can have the shittiest pickups, and still get blazing tone if you use the right strings. OK .... I usually designate my guitars by the tuning of the lowest string. A standard tuned 7 string would then be a B tuning. The smallest string you can buy, that I know of, is a .008 . This particular string diameter seems to work well when it is tuned to an A . That's a whole 4th higher than a normal tuning of the highest string on a guitar. If you were to raise the tuning on all of the strings of a 7 string guitar such that the highest string was an A, then the lowest string would be an E, which is the equivalent to a normally tuned low string on a 6 string guitar. I believe this is the highest possible tuning for a 7 string. The largest string that d'addario offers in a nickel XL is an .080 . I believe that a string this size on a guitar would be comfortable tuned to a C which is one half tone above the low B string on a 7 string bass. I believe this might define the lowest possible tuning for a 7 string guitar. Now, you're saying ........ good god, that's ridiculous. Well, with the guitar technologies that are available now, you would be surprised. And one thing is for sure. Even though the string is the same size as some of the bass strings out there, this is not a bass guitar. It's not a bass amp. It's not a bass string, and I'm not playing it through bass pickups. It's a totally different beast, and it is the DEATH guitar. When stringing guitars in such an extreme fashion, one other problem is encountered. The bridges on a typical guitar are designed to handle string gauges of a certain size. When a string is used that is significantly larger than what the bridge was designed to accomodate, the string rides on top of the bridge, and is not supported the way it should be, ultimately resulting in poor sound. Eventually, I will redesign the bridges to accomodate the larger strings. As you can tell, I have a lot of experimenting to do, and I need to buy more guitars!!! Without further ado, here are the different tunings with the string gauges that are currently in place. 7 STRING GUITARS ( standard tuning intervals ) E>.042 A>.034 D>.021 G>.014 C>.012 E>.010 A>.008 D>.046 G>.036 C>.024 F>.016 Bb>.013 D>.010 G>.008 A>.050 D>.042 G>.036 C>.022 F>.018 A>.012 D>.009 esp (A)7 G>.054 C>.046 F>.038 Bb>.030 E>.024 G>.017 C>.014 E>.056 A>.046 D>.040 G>.034 C>.028 E>.024 A>.017 D>.064 G>.056 C>.048 F>.040 Bb>.032 D>.026 G>.021 B>.067 E>.059 A>.049 D>.042 G>.034 B>.029 E>.024 7 STRING GUITARS ( thirds ) A>.056 C#>.046 F>.040 A>.034 C#>.028 F>.017 A>.012 dean (A 3rds)7 7 STRING GUITARS ( flatted thirds ) F>.035 Ab>.030 B>.024 D>.021 F>.017 Ab>.013 B>.011 ltd (F b3rds)7 G>.032 Bb>.028 C#>.024 E>.018 G>.015 Bb>.011 C#>.009 douglas scope (G b3rds)7 D>.080 F>.072 Ab>.064 B>.058 D>.051 F>.040 Ab>.028 douglas scope (D b3rds)7 B>.058 D>.051 F>.040 Ab>.028 B>.024 D>.022 F>.017 douglas scope (B b3rds)7 7 STRING GUITARS ( hybrid alternating flatted fifths and fourths ) D>.080 Ab>.072 Db>.057 G>.030 C>.024 F#>.017 B>.014 peavey (D hyb b5 4)7 7 STRING GUITARS ( hybrid alternating fifths and thirds ) G>.064 D>.050 F#>.034 C#>.016 F>.013 C>.010 E>.008 squier stagemaster (G hyb 5 3)7 7 STRING GUITARS ( hybrid alternating fifths and flatted fifths ) C>.080 G>.068 C#>.055 G#>.030 D>.017 A>.013 D#>.010 ibanez rga7 (C hyb 5 b5)7 7 STRING GUITARS ( special ) E>.089 G>.072 B>.052 F>.032 B>.024 F>.018 B>.012 douglas scope (EGBFBFB)7 6 STRING GUITARS ( duff memorial C(6) and other standard intervals ) C>.068 F>.052 Bb>.032 Eb>.026 G>.021 C>.017 duff fretless starfire (C)6 A>.036 D>.026 G>.020 C>.015 E>.009 A>.008 D>.049 G>.037 C>.028 F>.018 A>.014 D>.011 paul (D)6 Bb>.052 Eb>.038 Ab>.028 Db>.018 F>.014 Bb>.011 goldtone banjitar (Bb)6 E>.045 A>.028 D>.017 G>.032 B>.024 E>.016 adeline (E gambale)6 A>.032 D>.028 G>.024 C>.016 E>.018 A>.014 adeline (A gambale)6 6 STRING GUITARS ( fifths ) Bb>.052 F>.040 C>.028 G>.013 D>.009 A>.008 soprano strat (Bb 5ths)6 G>.056 D>.046 A>.036 E>.025 B>.017 F#>.011 E>.049 B>.038 F#>.030 Db>.024 Ab>.019 Eb>.014 Eb>.072 Bb>.064 F>.032 C>.024 G>.019 D>.013 SG (Eb 5ths)6 Ab>.068 Eb>.052 Bb>.028 F>.013 C>.011 G>.009 soprano strat (Ab 5ths)6 6 STRING GUITARS ( flatted fifths ) E>.059 Bb>.040 E>.042 Bb>.030 E>.024 Bb>.014 D>.046 Ab>.036 D>.026 Ab>.016 D>.013 Ab>.008 ibanez mikro (D b5ths)6 Bb>.046 E>.036 Bb>.026 E>.016 Bb>.013 E>.008 ibanez mikro (Bb b5ths)6 6 STRING GUITARS ( hybrid alternating fifths and flatted fifths ) G>.049 D>.038 Ab>.034 Eb>.022 A>.016 E>.011 jackson (G hyb 5 b5)6 6 STRING GUITARS ( hybrid alternating flatted fifths and fourths ) E>.072 A#>.059 D#>.044 A>.036 D>.022 G#>.014 memphis (E hyb b5 4)6 6 STRING GUITARS ( hybrid alternating fifths and thirds ) D>.044 A>.041 Db>.030 Ab>.013 C>.009 G>.008 esp f jr (D hyb 5 3)6 6 STRING GUITARS ( hybrid alternating fifths, flatted fifths and fourths ) C>.051 G>.030 C#>.023 F#>.015 C#>.009 G>.007 laguna (C hyb 5 b5 4)6 6 STRING GUITARS ( thirds ) F#>.046 Bb>.031 D>.023 F#>.018 Bb>.014 D>.011 fender squier mini (F# 3rds)6 12 STRING GUITARS ( standard intervals ) A>.021 D>.019 G>.017 C>.009 E>.014 A>.011 rickenbacker A>.049 D>.037 G>.028 C>.018 E>.014 A>.011 D>.019 G>.017 C>.015 F>.008 A>.012 D>.010 rickenbacker D>.044 G>.033 C>.025 F>.016 A>.012 D>.010 8 STRING LAP STEEL GUITARS ( hybrid 2 b3 3 2 b3 3 2 ) B>.043 C#>.039 E>.030 G#>.028 Bb>.024 C#>.018 F>.015 G>.014 vorson BASSES C>.090 F>.070 Bb>.050 Eb>.035 rickenbacker C>.095 F>.075 Bb>.055 Eb>.040 fender fretless jazz G>.104 C>.091 F>.078 Bb>.065 Eb>.045 Ab>.030 Db>.020 conklin G>.095 C>.085 F>.070 Bb>.055 Eb>.040 Ab>.025 ibanez fretless D>.160 G>.110 C>.090 F>.070 Bb>.050 Eb>.035 Ab>.025 Db>.020 galveston C>.090 G>.060 D>.030 A>.020 cecilio
