Ampworx Vintage Series Preamp Pedals
We all love a great vintage guitar amp, but what makes it unique? The sonic flavour, or how it looks and feels? It’s a personal matter, and we found that, in most cases, it’s a combination of things that ignites their vintage vibes.So, we covered all bases when we set out to recreate three classic vintage amps from scratch.Our AmpWorx technology is the sonic cornerstone, as we used it for modelling every component of the original amps. But we also teamed up with Celestion to find the perfect speaker IR match for each pedal and to preserve the look and feel. We stayed true to the intuitive control designs.
