GTR® (Peterson) is a proprietary electric and acoustic guitar setting geared toward “sweetening” the 4th and 5th intervals on a standard tuned or ½-step-flat guitar (and bass when played in combination with a GTR-tuned guitar). GTR improves other intervals as well. For best results, use the default EQU temperament for intonation (string length setting), then tune open strings using GTR.

BAS® (Peterson) is a proprietary bass Sweetener™ useful for percussive playing and when playing along with a stretch-tuned keyboard (acoustic piano or other string or bar-struck keyboard). For best results, use the default EQU temperament for intonation (string length setting), then tune open strings using BAS.
BFTS® (Buzz Feiten Tuning System) The Buzz Feiten Tuning System is a tempered tuning formula which uses a compensated nut and saddle to correct intonation problems on stringed, fretted instruments. Buzz Feiten-equipped instruments can take advantage of preset open string and intonation settings within StroboSoft™.
Note: The SWEETENERS™ section is part of the complete profile that you can create and store inside StroboSoft™ for your instrument. It should be noted that Sweeteners apply to a particular tuning and the creation of new Sweeteners rely on the tuning being appropriate for the instrument. |
