A case in a wood that suits your room. A front panel in a different finish. Solid timber cheeks on an amplifier that left the factory in plain sheet metal. Lighting with a warmer glow. Work of this kind changes nothing in the circuit and everything in the impression.
Materials and execution we discuss beforehand using samples, not descriptions — wood and finishes look different on a screen from the way they look in a living room. Work begins only once you have held the material in your hand.
