Ian, I wondered what kind of music you'd be making on this Stringmaster. Brad's got some nice suggestions as it stands.
I think he said A6 and listed C6, both have several variations. Lots of western swing has been played on both tunings as well as the E13.
The "Jerry Byrd" tuning, C6/A7 is nice to have because it's so versatile. For 7 string it goes:
E
C
A
G
E
C#
C
He's used it to play Hawaiian, Pop, Country, Spanish.
Some of us are using a close relative of this tuning, a C major pentatonic, the bottom D can be retuned on the fly for the C6/A7. It's not a strum tuning, but offers the advantages of the C6th plus somewhat easier scale/mode pockets IMO.
D (pitch is between 2nd str E & 3rd str C)
E
C
A
G
E
D
C
This one can be retuned for the following tuning, but with slightly altered grips.
Also, if you're looking for a modern, unique tuning that can play some fuller pop chords, the Leavitt tuning is an interesting approach. This is the low bass version.
D .017
C .018
Bb .021
G .024w
E .030w
C# .036w
Eb .058w
C .064w
Forumite/musician Mike Ihde has some nice cassettes & tab available on this tuning.
I have a T8 Stringmaster, mid 50's. The nut doesn't adjust up or down. The bridges have intonation adjustments at each end and should be adjusted (once you settle on your string gauges and tunings) to get the 12th string harmonics to be right over the 12th fret.
IMO, the point of departure for pickup heights should be 3/16" from top of pickup to bottom of strings. From there adjust bass or treble sides up or down to get best string response for given tuning. I'd avoid having the pickups up high enough so that the strings contact the tops of the pickup while you're playing. If you've got the blend controls, my favored setting is full clockwise - i.e. both pickups full on - gives fuller, richer low end.
Check out Brad's Page of Steel for more tunings, or feel free to post some more questions.
Hope this helps, Bob[This message was edited by Bob Kagy on 22 June 2000 at 03:39 PM.]
