Round Core (not Hex Core) Steel Hand Crafted Strings. Read more about the difference below.

Watch how a handmade string is born:


"The original PB*Round was designed by Guadalupe Custom Strings founder, Francisco Gonzalez.  I continue to make the formula for Phosphor Bronze 13 gauge strings today.  I built the rest of the line of acoustic from extensive testing and feedback from both players and luthiers. This line definitely builds on the classic punchy sound of the PB*Round string set while offering consistent tone and more durability without the use of any additives or coatings.  

For Resonators, I recommend 13 or 14 gauge PhosphorBronze, remember to opt for Tailpiece length strings which feature the stronger and tighter LongTwists.  

I personally love the result of Brass 12s on Taylor x14 sized guitars and Brass 13s on Gibson J45s.  "

A HandMade Tradition

"Gabriel Tenorio Strings (GTS) are made solely by hand using traditional techniques that are far too labor intensive and costly for the vast majority of string companies.

For over 20 years, we have worked with luthiers, builders, players, and technicians around the world to develop the highest quality strings available.

We are a very small workshop with less than a handful of string makers."



"We only use the highest quality American made products including Round Core steel.  Round Core steel is the key to making a superior metal string.  Hex-Core provides a very inexpensive and accessible string to the mass consumer, however a great deal of the value of the string itself is compromised.  Many string companies may claim customized strings, but we've been doing that for 20 years.  Some may claim to actually wind by hand, unless they are using round core, there is no comparison."

Milkman Sound "They are amazing--have to say that I'm a convert!... Great Strings! I was in twang heaven last night! My lead tone was outrageous. Pedal steel players have a phrase: string separation. It applies here, too!" "I had a great gig with those strings. My Tele sounded more "Tele" than it ever has before. Your strings - my amp - and that Creston guitar is a *crazy* good rig!" TM

Ryan Ashley "Gabriel Tenorio, you have totally let me down!! your stupid string broke on me...after only 14 months! Screw you, man!!" RA

Scero Guitars "I mean sure, the strings are perfect, a joy to play, don't wanna use anything else ever... all i use on my customers' guitars now" LS

Wilborn Guitars "I would describe them as very rich and warm.  They really brought out some color and depth in my double top OM. None of the jangle of new 80/20 strings.  Very cool. Ilove the fact that they are made by a real person tending to each string.  They also produce a very steady tone-my strobe tuner reads them very well. Kudos to Guadalupe Custom Strings!" BW

Porter Pickups "...strings are killer.  As someone who makes his living winding, I'd say he's a pretty good winder in his own right!" BP

Schuyler Dean Pickups "Excellent strings!" SD

Recycled Pedal Boards "I like to stay away from superlatives like, "best," "greatest," etc., because everything is subjective...but [Guadalupe Custom] Strings are right up there with my personal favorites...they might be at the top of the heap. Hand wound, in a little shop, making a living! These are the folks I like to give my money to."  CS
