When a RUclips video asks a yes or no question, bet on the answer being no. Nevertheless, analysis would be great to understand how instrument design relates to sonics.

Hmm. Could we see the test on a guitar strung up to pitch. Then when it is un-strung . Also use a fiddle bow to energize the strings instead of the present popular method. It would be more revealing. The top plate undulates much differently when stressed with string tension. Also electromagnetic excitation is only good for certain results.

Fabulous! Love the approach! Is there a way visualize multiple dimensions measured, like frequency, strength and decay time in a single 3D waterfall plot? Lots of computing needed for that I would guess.

Wow!

Are you recording the guitar flat?

Se habla mucho de teoría pero no hay ninguna demostración de sus guitarras... ¿qué sentido tiene? Mostrar las guitarras y algo de sonido. Somos guitarristas, no constructores.

I learned on a 13 mm and I live with it. It came handy when I picked up a double bass. I only leaned a soft touch on violin where you don't have to, and shouldn't, most of the time, press all the way to the fingerboard. Now I am designing my own guitar and I am still undecided on what action to choose. I guess I will go with heavy gauge steel strings, slightly longer scale length and low action to make the strings tight, as I play alternate picking tremolos with single finger flesh, and the nylons are jumping too much when I play loud, while the steel strings return themselves in time for the next stroke. I guess 2.4 and 1.6 mm could be good, plus the old guitar for playing violently.

Tengo el honor de poseer una guitarra clásica construida por el Sr. Jesus Bellido. Es muy ligera con un sonido magnífico y muy cómoda para tocar.

No tiene ni puñetera idea de lo que está diciendo. Explicar no es lo tuyo desde luego.

Nice guitar design, the head and the rosette ,well done Ahmad .

Mas o menos que seria el precio de una guitarra como esa--en España, gracias

24:40 Spanish guitar maker Casimiro Lozano makes Double Top guitars .

Wow, great interview with a fine maker, really enjoyed his insights and in depth explanations, lots to think about here, thank you!

Grazie mille!

32:30 debe ser por eso que la mayoria de las guitarras de fabrica tienen una pesima afinacion ... me pregunto a quien se referira al final del video , alguien por ahi destruyo una leona "corrigiendo" las medidas ? 39:40 no me digas que le hicieron eso a una original torres ?? :o

Great maker. What is the disadvantage of a zero fret? Lowest possible action, straightforward fitting and far less time-consuming. Sorry, ggeorge already said this.

cuando dice triple a que se refiere ??

Que hermosa guitarra...

This is the best video I have seen on this subject with a level of detail that does not leave doubts in your mind. At a higher level I can see many of the ideas can be generalized to acoustic and electric guitars

Muchas gracias.

Great instrument...

outstanding!

fantastic !!!

mi guitarra clasica la configure de la siguiente forma. uso cuerdas tension normal, cambie cejuela y selleta por unas de hueso real ya que da mas sustain y mejora bastante el sonido a la guitarra. altura en cejuela, (E .50mm) (A .45mm) (D .40mm) (G .50mm) (B .45mm) (E .40mm) y en selleta 2.75mm y no tiene zumbidos. para mi es la configuracion ideal, claro esta que cada quien tiene gustos diferentes, tambien depende la tecnica y forma de ataque con los dedos etc... creo que los zumbidos son mas propensos cuando bajas demasiado la cejuela ya que es mas delicado el ajuste. pero igual si no te quitas el miedo hacerle mantenimiento y ajustar tu instrumento entonces jamas podras tener un instrumento comodo a tus gustos y necesidades (solamente que pagues a alguien claro esta) realmente es algo sencillo solo hacer las medidas con precaucion y listo. ademas si estropeas la cejuela o la selleta todo tiene solucion. es facil de conseguir y cuesta 50 pesos mx. o 3 usd.

Sehr gutes Interview - Ich habe eine Andres Marvi Ceder Gitarre von 2004 (Nr.159) - ein phantastisches Instrument: voluminöser, warmer aber glasklarer Klang wie aus einer Glocke und einem Cello zusammen, ausgeglichen in allen Lagen und auf allen Saiten. Nach direktem Vergleich mit einer Ignatio Fleta (die auch Spitze ist) würde ich nicht tauschen. Weiterhin alles Gute Andres - Paul Hutter

Gracias Javi por tu trabajo. Paco de Granada

Very well explained. Yes, there are so many factors involved that it is better to go in person and play a few different guitars because you will know it when you feel it, you do not need to bring your ruler to the shop even. The scale also will have some impact, 640mm will be more comfortable than 660 mm. i prefer 2.5mm on the first string if possible. Thanks!

Hola Sergio!… muchas gracias por tu legado. Soy aficionado a la guitarra, y quiero agregar la construcción de guitarras a mis hobbies, y sueño hacer mi propia guitarra. Quiero preguntarte si tienes algún curso por internet, y si tu libro lo puedo conseguir en algún lado… o si me lo pudieras enviar a Mexico como PDF. Felicidades por tus logros, y que Dios siga bendiciendo tu trabajo!… quedo atento a tu respuesta… gracias!

La mision del tornavoz, es Ademas de modificar los bajos . Es proteger el interior , de la caja de la humedad del smbiente.

At 18.5 he says "wolf notes here or there"---Well if you stick a tape label under the string and write what those notes are you will find they are all the same note . I had one with 5 dead notes --all on Bb--. Use some bluetack stuck on the bridge to make those notes resonate . .One guitar only needed 10.5 grams of weight to clear those notes . Substitute the bluetack with Stainless steel rod 1/4 inch thick and glue to the bridge under the strings with Evostik . Each dead note "cured" also improves the notes above and below.So you get three note improvements each time . This was on a Roca guitar with a nice tone .

The best sound comes from adding another fret where the nut goes. I have done this with my guitars. Then there are no adjustment slots to be concerned about, the tone is the same on open notes as fretted notes, and it plays exactly the same on all frets.

Sin dudas unas de las mejores entrevistas que has hecho,humildad y sabiduría ….pero que bonito poder terminar con el sonido de una de sus guitarras……. The cherry on the cake!

Very nice playing 🎉

Bravo 🎉

Bravo 🎉

Real masterclass Marcus! 🙏🙏
