I just came online to tell you guys about some of the experimenting I did today, and to declare my undying and unconditional love for my 2 fretless AC6s, my AC6 Classic and my AC6 Signature.
I decided to make today a day for quality time with my basses. Among the things I did was to remove the black coated strings my AC6 Classic shipped with and replaced them with Thomastik Infeld Jazz Flats.
Ordinarily I replace strings with fresh strings, but TIJFs take about a month to break in, and they have a different tone when they are broken in, and since I didn't want to wait to know what they would sound like on the Classic, I pulled the broken in set off my AC6 Signature and put them on the AC6 Classic.
The tension difference is dramatic so the neck got reacquainted with Allen (Wrench). Once I got it right, I couldn't put it down; what a BLAST to play with such a full, warm acoustic tone on a 6 string bass guitar.
My AC6 Signature got a set of DR DDTs (drop down tuning) -- a fresh set of course. DDTs don't come in 6-string sets, so I used a TIJF C string. The DDTs are no where near as versatile as the TIJFs, but I don't care. With the DDTs my AC6 Signature can't do an acoustic sounding tone anymore, but I have another bass for that anyway. Now my AC6 Signature has a WONDERFUL, thick, rich, articulate electric fretless tone I'm totally in love with. Absolutely and unconditionally.
I got the idea of using the DR DDTs from from Edmond Gilmore.
Check out his AC5 with the DDTs in this video.
I have owned, I don't know, several fretless basses. I liked them all well enough, but I knew too that none of them were "the one." Not so anymore.
I have one fretless bass that has such a pleasant acoustic tone I can't wait to bring it gigging and show it off.
And I have another fretless that gives me 6 strings of lush, lively mwah. I have no idea how I can squeeze that into a gig with the music I usually get to do, but that won't stop me from trying.
ACs have been called "The King of Fretless Basses" and they truly are.
