Vintage 70's recording gear. A smooth, natural sounding reverb
From the original ad ... The Master Room XL -305 is a totally new design approach in reverberation technology. For the first time, the qualities and properties of a live acoustic chamber are available in a rack mount unit at an affordable price. There is a natural sound on percussion, as well as voices and all other musical instruments. This quality has not been obtainable from other compact reverberation devices. The XL -305 exhibits no unwanted side effects; it's as natural as a live chamber itself. To hear this new advancement in reverberation, see your professional audio dealer and ask for a demonstration of this exciting new unit. Hear the XL-305 "Acoustic Chamber Synthesizer" for yourself, and you too will agree .. It's INCREDIBLE.
