What is the difference between classical and flamenco strings?

Flamenco black nylon strings are darker, warmer, and more mellifluous on most classical guitars. If your classical is bright and forceful they are dream because they find a happy medium. If your guitar is already warm and dark they don't really work.

I'm new to Flamenco and was told to buy Normal tension - but can't find it on Amazon. So, what's the difference between Custom tension and Normal?

You would be best served by buying normal tension since you are new to Flamenco. Varying tension strengths means different levels of pitch to a large extent. In these days manufacturing is so accurate and so advanced musicians can acheieve sounds they want by using different tensions, usually a specfic set of tensions on a specific guitar. You could easily buy two sets of normal strings and one set of custom and change them about if you wanted to experiment. But best to start with norma alnd experiment later as you develop technique.

are these rectified nylon strings?

I believe D'Addario packaging indicates whether or not the contents are rectified.

Trying to adapt a steel string guitar to nylon strings, would these work? Thanks.

No. There are folk style nylon strings that have the little nubs on the ends that let them fit into the bridge with pins similar to steel strings. These classical strings have to be tied into the bridge.

Excellent choice - if you like the tone

I have tried various strings on my flamenco guitar - Daddario EJ45, Hannabach and Tomatito which all gave a sound that I liked and sounded good whether playing classical or flamenco music. I thought I'd give these a try and the difference in tone has been amazing. The guitar now really sounds like a flamenco guitar, with plenty of "attack", but the downside is that it doesn't sound as good when playing classical pieces. I appreciate that every guitar is different and it may just be the effect on my guitar which may not be the same as someone else's. As other reviewers have said, they do need breaking in but for me it's worth it. And for the classical pieces - maybe it's a reason to buy another guitar ......

TELLERDEKİ ENTONASYON SORUNU !!

Böylesine entonasyon sorunu olan bir tel ne gördüm ne duydum. Profesyonel stüdyo ve sahne gitaristliği yapıyorum. Esteve 9F Blanca gitarım için kayıtlarda kullanmak üzere denemek istedim telleri. 2. gün söktüm attım. Böylesine entonasyon sorunu Alice marka üç kuruşluk tellerde bile yok. Sakın ha sakın almayın
