The RG90-4's cabinet is constructed from high-quality plywood, ensuring durability and resonance. It features a pair of 12-inch Celestion speakers, renowned for their ability to deliver clear, powerful sound with just the right amount of warmth and character. These speakers work in harmony with the amplifier to produce a sound that is rich, full, and responsive to your playing.

Adding to the amplifier's vintage charm is its traditional design, with a simple, easy-to-use control panel and a distinctive silver-faced fascia. The RG90-4 also sports a pair of input jacks for foot-controlled effects, making it easy to integrate pedals into your setup for even more tonal possibilities.
