Discover the Magic of Vintage Tone with the Fuzz Audio Preamp Tube Collector Pack

Unlock the full potential of your amp with the Fuzz Audio Preamp Tube Collector Pack. This exclusive set is designed for musicians who want to dive deep into the world of vintage tones.

Did You Know? Stevie Ray Vaughn achieved his iconic sound by using a 5751 tube in place of a 12AX7. By simply swapping a preamp tube, you can transform your amp's character and discover tones that resonate uniquely with you.

Customize Your Sound Does your amp sound too sharp? Soften it with a 12AY7 or 5751 tube. Need a stable base for your effects pedals, but your Fender Deluxe Reverb is too aggressive? The 12AU7 or 12AT7 will mellow it out.

Remember, music is personal. Experimenting with different preamp tubes lets you find the tone that speaks to your soul.

Why Vintage? Vintage tubes are renowned for their superior sound and durability. This collector pack includes hand-tested, collectible tubes from the USA, crafted over 50 years ago. Modern tubes simply don't compare.

Dive into the world of vintage sound with Fuzz Audio's Preamp Tube Collector Pack. Discover your sound. Elevate your music.

At Fuzz Audio, all vintage/NOS vacuum tubes purchased through our website are guaranteed for one year from purchase date. We accept returns for tubes going noisy, losing output/performance prematurely, and of course losing function all together.  (Read about power tubes below). 

We will not cover damage from red plating neglect, glass breakage of any kind, loose bases, or other obvious faults that are due to neglect, rough handling or egregious constant use. 

This policy is meant to protect the buyer from having a tube go out on them prematurely from a flaw we missed. Tubes, especially preamp tubes, should last half a lifetime, and well beyond a year, so we want to guarantee each customer that you get a tube that will last.

For power tubes, although we will honor any faults mentioned above, we will not accept a return for a power tube that has obviously been used for 6+ hours a day for every day of the year for one year. Power tubes that have clearly been used beyond their normal wear point will not be accepted. 

If you suspect one of your vintage Fuzz Audio tubes has gone bad within one year of purchasing, simply reach out via our chat or at and we will assist you in the warranty exchange process. No receipt is needed.

Please note, it is possible we will be out of stock of the tube that is in need of a swap. If this is the case, we will either offer a refund, credit, different tube, or send the first available tube of that type when it comes back in stock. 

If you have any questions or concerns, please reach out!
