Thomastik strings for acoustic guitar Spectrum Bronze Series nickel-free set SB112 medium light .012-.054

Have used Thomastik strings for years, definitely the best available, just great to get them at a reasonable price for a change.

Quality strings, they make my Dowina acoustic sound far better than the strings fitted from new. Deep bass noticable mids and bright highs.

These are the best strings we have ever used, been using them for years. Not cheap, but in this case you get what you pay for

Well worth the money ,rich sound from them

I play jazz on archtop guitars and Thomastik is my go-to string brand for electric archtops. I thought it would be the best choice for acoustic archtop too. Therefore, I tried the spectrums. Unfortunately, these strings are not long enough for acoustics archtops. These strings are purely for flattop guitars. This is not mentioned though in the product description or the website. So, it was a waste of money and time. And they are not cheap.

I put a set of 12's on my guitar around 2 months ago and they are still resonant and musical. They also hold their tuning and intonation extremely well. For uncoated strings they really do last a long time. I usually prefer phosphor bronze strings as I find bronze strings too bright and a little shrill. Not so with these spectrums, they have a warmth to the low mids and never sound harsh. Great strings and well worth the price I think.

Acabo de probar estas cuerdas en mi Yamaha FSX5, que trae de fábrica unas ELIXIR 12-53 Bronce 80/20. El sonido de las THOMASTIK es indudablemente mucho mejor, más completo, menos chillón, sin llegar a ser apagado. No deslizan tan suave como las ELIXIR pero a cambio son bastante más blandas y se tocan como unas cuerdas de un calibre inferior, son muy muy cómodas. Sólo falta por comprobar la duración de las cuerdas para corroborar su excelencia, pero por ahora son 5/5

I really like the sound and the feel of the round core. Big fan of DR Strings in general. I tried these in place of my regular acoustic strings which are DR Sunbeams. The Spectrums have a really nice sound. The most striking improvement is the enhanced presence of fundamental frequencies. This translates to notes with incredible definition and punch, particularly on my Bourgeois OM's lower register. Gone are the muddy lows – every bass note rings out true and clear, even with complex fingerpicking patterns. This is my first set, so the question really is...how long will they last? If they die quick, I may just go back to the Sunbeams and change more often. The Spectrums are expensive. A few weeks in, they still sound good. They seem worth it so far!

I’ve tried almost every imaginable accoustic guitar strings in over 50 years and this is still simply the best for me. They’ll sound clear and crisp for ever. From finger picking to heavier strumming.

Great on a acoustic/electric guitar.

Perfectas para dar más brillo y sonoridad a la guitarra. Quizá me habría gustado más comprar un número menor por aquello de que no fuesen tan gruesas. Pero aún así, no se sienten muy duras al pisar.
