It seems alot of this is directed at Al,but here are some thoughts.
To clarify why this is a bass is a good .It developed out of bass guitar"genetic code". It's 34" scale to 32" scale-definitly Bass territory,as well as the string spacing.The majority of the strings are bass strings.I play it with my fingers.It's range is lower than any bass guitar in existance,and lower than that of a grand piano. It doesn't get any "bassier' than that.The whole thing smells like bass.
Key Bass indicates bass played by keys with keyboard sounds,but fulfill the bass requirements.Why would a keyboard player ever have to play bass? Why would a bass player ever need to play keyboard parts?-same reason.I've been cut out of gigs because the leader made more money hiring a keyboard player who "kicks left hand bass".That keyboard player tells me"I wish I had a bass player,I hate playing left hand bass all night". I play solo bass gigs and I play the same tunes that a solo pianist would.I have same the harmonic knowledge and chops as a keyboard player. Why should I have to use their instrument to express myself?
For some reason,keyboard players became the center of the universe because they have the entire funtional range of the orchestra at their finger tips-well now so do we.
"And don't say "well a piano player most of the time doesn't need 88+ keys" because I'm talking about the size of the neck being a factor.
A keyboard player playing a C Maj scale anywhere on the keyboard is the same. Not true on a 9 or 11 string. "
-yes it's the same on a 9 and 11- the major scale formula stays the same on any instrument:
1-1 -1/2- 1-1-1- 1/2
"Erfsi (errf-see) noun; (also see ERB) Extended range fretted stringed instrument covering the full range of full piano yet played in a guitar or bass guitar like style."-
Not true-i play piano pieces in a piano style,and guitar and bass parts in the appropriate style.I have my own technique for playing that sounds best on a minmum of 7 strings. Buy my CD and listen carefully to the bass parts-that is why there is a 7 -string bass,11-string bass.The parts really need all those strings to create an original,unique texture.
I work commercial gigs with 7+ string basses and I play the bass parts with special modifications that enhance the sound of the ensemble.I can't do it on a 5 string.I play 4 string often. i love it.My bass parts exceed the range of a 4,5 or 6 string bass,especially on my original projects.I like making music with sounds that have never been heard before.
ERB in this case means "entire range bass" as in all notes. This one has 12 strings in line,a 92 note guitar.Why do you want to make up a name for these bass guitars?They look like bass guitars.Too big for regular guitars. The 12 goes higher than a guitar.There is nothing extended about it. It's it's own instrument. What defines "full range"? Certainly not a grand piano.A grand piano almost has the range of the in-line twelve.
"At what point and please excuse my limited knowlege of "ERB's" out side of owning a six in the past and just toying with a GT-7 (trust me, when I played it, it was toying!!) does the sheer size of the neck hinder your ability to play??"
At no point does the size of the neck hinder my playing-it's an Adler bass. The thinnest bass necks made.Adler made the bass for me-my specs knowing full well I don't want an unplayable monster.
"But one last thing, if you use the ERFSI(

) for what it is, sweet, but why the hell on a Venessa Williams gig, which could be played on a 5 (and maybe a 4) would you use something with a neck wide enough to land a plane on!You can't tell me VW music calls for the range of 9+ strings much if at all. With the exception of a solo spot or two."
How do you know that her gig could be played on a 4 or 5 string bass?
Al is on the gig because.............he is Al Caldwell-a gentleman, an excellent, professional musician. I think he knows best what bass to use.Maybe he plays the double stop note at measure 31 in quadruple stops,giving it a thick rich sound that only 4 notes can do.Won't sound the same on a five string.The neck may be wide to you, but not to Al.Maybe Al likes the way the bass sounds.
It's his gig, and his choice to use whatever he wants.Five strings really don't have the bass that a subcontra bass does,and playing F#0,G0,Ab0,A0 and Bb0 gives you a bass range that is incredible.A "normal" 5 gives you B0 as the lowest note,so on that big ending on an A chord-you only have that puny A1.For that reason alone an 11-string is valid.
"Wouldn't it just be more comfortable to just pull it out when you need the range as opposed to man handling that thing just to play in "normal" 5 string bass range most of the night?'
Man handlimg??? The bass is more comfortable than a lot of 5 and 6 strings.
I think you need to hear more Bb000-Bbo used then you won't settle fot B0 as being "normal".Check out Jauqo III-X's "Low C# Theory".It is a CD that is recorded using the Adler 4 string sub contra fretless bass.
This 12 string is the easiest bass I've ever played-I custom ordered the bass, so it's made for my needs. I don't want to be pulling out different basses on a gig or in the studio.
Al and I make our living with these basses .They may not make sense to you,but they are our everyday working tools.
