The Tone Bakery Creme Brulee Boost makes your lead tones sing and your rhythm tones warm and fat. It started life as a recreation of the most highly valued boost of all time, then we added a slight bump in the midrange to make it extra creamy. Think Warren Haynes/David Grissom. The Creme Brulee doesn't take anything away from your natural tone, it sounds like an extension of your amp. You might never shut it off!
