Testimonials from True Musicians:

We feel proud and honored to serve the string instruments community, by providing excellent technical support and assist to help you to find the best violin that will fulfill your needs!

"This violin far exceeds my expectations in the quality of the workmanship and wood, it's truly a beautiful piece of craftsmanship, the pictures on your website don't do it justice. I've played it for 2 hours and it responds evenly on all strings, a rich sonorous G string responding beautifully in high positions on all strings despite barely being played in. I've just played Paganini's 4th caprice on the violin, not easy on a familiar instrument but I was stunned how playing on this violin was so comfortable.

Anyone looking for a quality instrument at such a reasonable price need look no further than ifstrings.

Very best wishes,
George Ewart.

My name is Boris, I am a professional violinist, for 10 years I was assistant concertmaster at the Santiago de Chile Philharmonic. Now I am a violin teacher at the Catholic University of Valparaiso. I have purchased 4 Ifstring violins, all master series, and I can say, that is by far the best choice on the internet, in sound, workmanship, playability and price. I bought for my students many other similar violin online, but these are definitely superior. The last violin, surely not the last, see you soon. Thanks Ifstring!

I fully 1000% endorse the Master Build line of violins made by Leon Sheng. As a former concert artist (studying at the top music conservatories and with top coaches), I have been fortunate to have played on some of the most wonderful historical instruments gratefully loaned to me by various private patrons, including violins by Antonius Stradivarius, Guarnerius del Gesu, Nicolas Amati and Giovanni Paolo Maggini. Unfortunately, the duration of my loan for the Stradivarius and Guarnerius del Gesu violins are coming to an end soon. Therefore, I have acquired violins made by outstanding makers including Christophe Landon, Gregg Alf, and Nicolas Gilles. I have also tried and really like violins made by Frederic Chaudiere, Marco Coppiardi, Feng Jiang and Shan Jiang. One day, I happened to come across the website for Infinite Strings and the Master Build collection by Leon Sheng caught my attention. Out of curiosity, I ordered a trial of the “Soil” Stradivarius replica by Leon Sheng and I could not put the violin down. In addition, I ordered the Leon Sheng “Leduc” Guarnerius del Gesu replica for one of my top students and we both were awe-struck by the violin. I have shown these violins to top soloists and my trusted luthiers and we are all blown away specifically in the areas of tone (including projection and range of colors), appearance (including varnish), playability, and pattern/measurements of the original. They blow out any of the competition in the price range and actually match up in quality to the top contemporary and historical Cremonese makers. The only difference is affordability. In terms of affordability, I have always been on the look out for the best tone/quality/price violin for my students. I used to recommend the Scott Cao (STV-750, 850, or 1000), Jay Haide L’Ancienne, or Snow violins to my intermediate to advanced level students. Going forward, I will recommend the Leon Sheng Master Build. Finally, it has been a pleasure to do business with Lance. He offers great integrity and customer service. What an amazing discovery and I wish you the very best of success for your business. If any prospective customer has doubts or needs to talk to a live reference, have them contact me via email through my website.

"We are the proud owners of a Master Build Series violin, with the Vintage Modification, and a Viola, also with this modification. These instruments are extremely comfortable, responsive and have an amazing projection. The Viola is played by my husband who uses it everyday at the Puerto Rico Symphonic Orchestra, and it is now his instrument of choice, for its responsiveness and playability, over his well above 10K Stopka.  When working on my husband’s viola, they are able, from audio clips of famous instruments my husband gathered as a description of what he wanted, to alter the modification for this instrument until it had the same qualities. The violin is a copy of a Guarnerius and the impression from everyone who plays it is how well they were able to duplicate the “fat” or big round sound of a Guarnerius.  It offers the refinement found in older instruments, as some ot the characteristics found in 100 years plus violin I owned, but with the projection and power of comtemporary instruments, needed for today's highly demanding halls and violin orchestral/solo repertoire. But even above the high quality of this instruments, and how unbeatable they are for the price Infinite Strings sells them, the single most admirable quality about this company is their CUSTOMER SERVICE, quick, dependable, there is no question they will not answer, if you have problems with your instrument they will always respond, and their recordings, pictures and descriptions are always accurate. A pleasure to do business with, for real musicians, a their professionalism really puts buyers at ease regarding the quality of instrument they are receiving.These violins are addictive, most people that buy one, come back shortly for another one!

"Now that the 10 day trial period is almost over, I can tell you that I realy enjoy playing this instrument. In fact, it's well above what I first expected. It is now very close in terms of depth, projection, response and tone quality to some 20k Del Gesu copy that I've tried before. The dynamic range is very impressive as you advertised. I've had friends playing it and listening to me playing it. They all loved the way it sounds, reacts and feels.

"WOW! I just got done trying out the violin for about an hour, which I received today. I am incredibly impressed with the handling, sound, and maturity of an instrument so new. It is amazingly even across all of the strings, immediately and easily responsive, and quite rich and complex in its sound for a brand new, never-before played instrument. My "regular" violin is a beautiful 1702 Stainer model in the $80,000-$100,000 price range. I also have two very good 19th-century instruments, and several lesser 20th-century instruments. Yours is by far at the top of the heap after the Stainer -- no comparison to any of my others, and I feel as though once I break in your Guarnerius and play it regularly, it will sound even more spectacular. A fine, fine second instrument to back up my 18th-century violin at an unbelievable price. I have tried several "new" strad and guarneri copies in the past few years by well-known makers that sell in the $15,000-30,000 range -- I can tell you quite honestly, that this violin I now have is every bit as impressive. Keep up the fine work, and my infinite thanks!

"It has been about a year since I bought my fourth Master Build Cannone from you and although I continue to collect violins of all types and ages, I keep returning to this violin, which you said at the time has just the tone I want..... What I treasure about this violin is it's tremendous clarity of tone, very easy response, the warmth and roundness of the sound and the great depth I can pull out of the lower strings. This violin allows me to express the full range of my emotions in my playing, something that many others do not quite do.  Although I have several other finer level violins from China, none matches your Guarneri copies (of which at this point I still own three and have sold two to friends who wanted them). This violin, as well as the others I have from you, offers just as much warmth of tone....a golden sounding tone...as any of my antique violins, but adds more projection than any. Thank you so much for your wonderful instruments. The fine craftsmanship, beautiful wood and little bit of antiquing make this violin visually pleasing as well.
