TREBLE BOOST

In the past, the general idea of a treble booster was obtained by cutting the bass in half, and giving the treble more volume. Burns, however, have developed a new principle which leaves the bass exactly as it should be, and just boosts the treble. The sound is really fantastic. It is run from two V.T.4 batteries, which will last for a year. The surface noise is practically non-existent, and the whole unit costs 6 gns.
