    The return of Warr Guitars tapping instruments. New headless, multiscale designs.

    https://www.warrguitars.com/ Mark Warr is beginning to build again. See the 'Phoenix' webpage for renders of the new designs. There is a 'multinut' 'uncrossed hands technique' design, and a 'crossed hands technique' design. Looks like these might rotate on a single large pivot located at the...

    System for Just Intonation on guitar with standard frets (improved minor thirds version)

    This thread is related to my earlier thread https://sevenstring.org/threads/just-intonation-on-a-normal-guitar-by-restringing-and-retuning.335492/ A new thread has been started because the system is now using a superior minor thirds base tuning, and because i am presenting the system in a new...

    Fifths plus minor thirds tuning: Chord shape consistency

    Recently i have become interested in minor thirds tuning, for 2 reasons: 1. It is the optimum tuning for my 'Just Intonation on normal frets' system, detailed in this thread https://www.sevenstring.org/threads/just-intonation-on-a-normal-guitar-by-restringing-and-retuning.335492/. 2. I like jazz...

    'Grand Board' 12 string tapper, by Vellmor Guitars of Japan

    Good to see another tapper from Japan. I liked the Japanese 'Koyabu Symmetric Board' which is no longer in production. I like the name and how it suggests a grand piano. Very good to see this has a 36" scale, ideal for a tapper that loses scale length due to the string damper. Strap button...

    Kemp 'lumped' bass strings for reducing inharmonicity (plus useful physics content)

    https://kempstrings.com/product/lumped-45s/ String physics and experimentation were used to develop a short fatter section near the saddle, this seems to reduce inharmonicity when playing on higher frets. The research paper contains a lot of useful string physics information in one place, i...

    Bridge hardware design idea: String clamp saddle blocks

    Description --------------- Imagine a bridge saddle block of a fixed-bridge guitar or bass guitar. My proposal is that the string passes over the saddle, deflects downwards at the usual break angle, and then immediately passes into a string clamp mounted on the saddle block just behind the...

    New Standard Tuning / Fripp / Guitar Craft / Crafty fifths tuning: Original vision and variants

    The original vision was all-fifths --------------------------------------- From around 1993 and through the 1990s i was very interested in Robert Fripp and related projects, and collected as much information as i could. The information available then described Robert Fripp's September 1983...

    New subforum for strings / gauges / tension / scale / tunings or alter existing subforum description

    Strings and related subjects are a fundamental category, but i am always confused where to post. The most suitable subforum seems to be 'Pickups, electronics & general tech', but strings would then come under '& other guitar hardware' which seems understated for their importance, and i'm not...

    A (hopefully) clear explanation and summary of True Temperament fretting

    The recent thread about True Temperament is quite technical, the first post of this thread is intended to be a more easily understood explanation and summary. Later posts could perhaps be a place for people to ask questions about it. ///////////////////////////////////////// True...

    True Temperament fretting in detail (using an archive of the old site)

    The 'True Temperament' (TT) fretting system was recently discussed in a Facebook microtonality group, and an archive of the old TT site was discovered. There is a lot of misunderstanding of TT, and the old TT site was far more informative, so the intention of this thread is to link to the...

    GigaRackett by Richard Bobo, plays down to 6Hz (video)

    Good ammunition for when people claim that an extended range bass guitar can't be heard if the fundamental goes below 20Hz (*sigh*). This is clear and audible down to 6Hz. GigaRackett at 11:09. Chromatic scale from 12Hz to 6Hz at 14:35.

    Change bass guitar section title to include extended range bass

    Easy change that would encourage ERBassists, who currently have no home outside Facebook, to join and give that quiet section some more life. Creates consistency with the guitar sections. Maybe: "Bass / Extended Range Bass Discussion". ?
