Sporting a simple three-knob layout for volume, treble, and speed that summons whirling sounds from lush waves to whirring torrents, the Danelectro Billionaire Big Spender Spinning Speaker captures true rotary tone in a compact and affordable piece of gear. Kick in the Ramp switch to direct the flow of the signal up or down for lilting soundscapes that could fill a canyon. An excellent experimental addition to any board.
