The Universal Audio Ruby '63 Top Boost Amplifier is a premium amp-in-a-box pedal, designed to deliver the rich, chimey tones of a legendary '60s British valve combo. Whether you need jangly cleans, complex overdrive, or immersive vibrato, the Ruby '63 provides authentic vintage amp character with studio-grade clarity.

At its core, the Ruby '63 features faithful modelling of a classic British valve amp, ensuring organic warmth, dynamic response, and touch-sensitive breakup. The built-in vibrato captures the immersive depth of classic studio effects, making this pedal perfect for Britpop, rock, and indie tones.

The pedal includes three distinct amp channels, inspired by iconic British circuits:

• Normal - Warm, balanced tone with smooth breakup.
• Brilliant - Bright, chimey response with enhanced treble clarity.
• Vibrato - Classic modulated textures with lush movement.

Players can engage classic boost circuits, including a Dallas Rangemaster treble booster and a Maestro EP-3 preamp, adding extra harmonic richness to their signal chain.

With stereo I/O, the Ruby '63 enables immersive amp tones, making it perfect for direct recording, live performance, and pedalboard integration.
