"I am astounded by the Black Box as well, and normally not astounded without great difficulty. Weir called me to tell me about it. That's unusual. You know it's got to be good. Now, I already had one because I dabble in the steel guitar thing, but he had one really interesting observation preceded by a long disclaimer about not being too mystical or new age-y about it. He said that 'alchemically you're putting fire first', which I interpreted as "you're introducing this element right from the start" so, ok. Fire. But that's kind of a schematic interpretation, I think mabe fire just gets you to places you can't get to without fire. Which is pretty much what the Black Box does, it takes you to a couple of very useful places that you just can't get to without it. It's difficult to even relate exactly what it does if you haven't used one, it's not an "effects pedal", but the results are simultaneously very subtle and quite dramatic. It's an excellent tool."

"The dark, selfish, Gollum side of me wants to keep my new Precious a secret....However, my indebtedness to the vast pool of information that is TGP (The Gear Page) dictates that I must share this incredible find with my Gear Headed Brethren. In short, yes, you need Sarno's Black Box. It gives you all that's promised and more. If you are tired and sickened by tone loss on your pedalboard, hear this call and follow the light. I promise you, this is no ordinary buffer. You will be astounded. That's all I'm sayin'!!!"

"I'm loving you Black Box. It's making my guitars explosive!"

"WOW! What an incredible difference and improvement to my tone. The Black Box smoothed out my tone while giving it more depth and a bigger dimension. I can't imagine playing without it now. I really believe in this product. It is like hearing fm radio for the first time after listening to an unclear channel on an a.m. pocket radio."

"The STEEL GUITAR BLACK BOX” is one of the greatest pieces of gear to come along for steel guitar in a long time. With the BLACK BOX, I can get the power and punch from my solid state amps, and enjoy the warmth and tube sound like that of a vintage tube amp."

"SWEET, SMOOTH, and WARMTH with a SUPERIOR CHILL FACTOR" were the terms used to describe the sound of my guitar... I also have a Martin D-35 with a Fishman Matrix pickup, and the Martin sounds like "buttah" through the "Black Box" ... You're definitely right when you say the guitar sounds like wood and strings and NOT like a pickup when the "Black Box" is used... Thanks!!!"

" I just wanted to tell you that I was just overdubbing a steel solo on the new Gretchen Wilson album.....and they asked if I could get a little "fatter" sound. I plugged in your Black Box and the producer's eyes lit right up!!! I'd say we hit a tonal home run!!"

" I received the Black Boxes in good condition yesterday. Thank you, they look great! They look indestructible. I plugged one in and ran my Acoustic guitar through it into my old Gibson amp. 1. the Sunrise. I noticed an increased signal (sunrise has very low signal strength) tuned the vary Z in. Sounds great, smooth and very acoustic. 2. the  K & K's..Really smoothed out the "nails on the chalkboard" in the high end. Also seemed to even out string volumes. This sounds great! Can't wait to use these with my String Cheese setup!!"

"I have nothing but praise for the Black Box and for your creativity and development of it. My opinion, for what it is worth, every steel player in the world needs the Black Box. Thank you from a satisfied customer."
