Our Mission


Foundling Audio Labs was created to offer all the essential qualities of handmade, tube-based audio equipment at an unpretentious price point. We believe great sound should not be the sole prerogative of the wealthy, and that more accessibility to tube gear will only strengthen the continuing appreciation of these devices for generations to come.

our mission

Our Approach


We are not necessarily interested in reproducing museum pieces precisely as they once were, but rather in creating practical items that are better suited to a user's needs today. Foundling's unique, original designs are elegantly and unapologetically simple, and thus beautiful examples of what makes tube sound so incomparable. Our goal is a versatility and usability that lives up to the legendary originals, but also improves upon their often temperamental nature.

our mission

Our Quality


With a gentle and iconoclastic pushback against common notions of magic and fad-driven myths, our components are carefully selected and artfully combined based on tangible results from exhaustive R&D. In an age of oft-repeated nonsense and poorly-informed internet lore, we honor our ears above all else. Simply put, we build what will sound best with the greatest reliability as cost-effectively as possible.

REVIEWS / TESTIMONIALS

⭐⭐⭐⭐⭐

I am blown away! This amp is incredible and the tones across the entire spectrum are fantastic. I got more than what I was hoping for in this little monster. Running it through an open back 1x12 cab with a vintage 30. Bodie was awesome to work with, was able to accommodate my requests, kept me well informed on progress and options, and had it turned around quickly. Outstanding product and service.

⭐⭐⭐⭐⭐

The sound from my Rapscallion is so unbelievably organic, beautiful, raw and a complete shocker when I first heard it; it still laves me in awe every time I turn it on. The sound washes over me and surrounds me. It has THE BEST sound just before breakup and the response to my playing aggressive and then softly is divine. The attention to detail under the hood is impeccable. It is capable of so much with effects but most of the time I just play straight in. I love this amp so much and it is an absolute jem. It has secured its place amongst my most coveted amps in my collection. Above any vintage Marshall, Orange or Fender, and I own them all. I wish you the best for any future endeavors but sometimes I wish this little guy stays my little secret πŸ™‚ -Graci

⭐⭐⭐⭐⭐

This amp is fantastic. When you have a great amp you only need one knob. It is voiced amazing, is very dynamic, I run it through a 1x10 with a warehouse green beret and it sounds fantastic. It also takes pedals well. One other thing to note is it is super quiet. This circuit has basically zero noise. If you are in the market for a 5 watt amp head, buy this one.
