Frequently Asked Questions (FAQ)
What exactly does a lefreQue do?
A lefreQue sound bridge connects different parts of your instrument in a unique and patented way, allowing vibrations to be transmitted more effectively. This results in more resonance, better intonation, and more powerful projection.
For which instruments is lefreQue suitable?
The lefreQue sound bridge has been developed for all brass and woodwind instruments such as:
- flute
- saxophone
- clarinet
- trumpet
- french horn
- trombone
- euphonium
- tuba
- sousaphone
- and more
The IntoniQue series is also suitable for string instruments, such as guitar, violin, and harp.
What is the difference between lefreQue and IntoniQue?
- The lefreQue sound bridge is for bridging parts of the tube of a wind instrument.
- The IntoniQue bridges the inside and outside of the body of a stringed instrument or a body of a wind instrument. But also, the front and back of the headstock of a guitar.
- Both products improve sound, intonation, and projection, but in a different and complementary way.
What kind of difference can I expect?
Most players experience:
- more resonance
- better intonation
- more projection
- a faster responce
- feel more connected to the instrument
- The effect is immediately notable.
Does lefreQue have a solution for every instrument?
For almost every instrument (string or wind), a sound bridge or an IntoniQue, or both together, can bring about a huge improvement.
Are lefreQue products only for beginners?
Certainly not. lefreQue is used by:
- beginners
- advanced players
- professional musicians
- orchestras worldwide
Even on top level instruments, the improvement is surprisingly large.
Can the use of lefreQue replace buying a more expensive instrument?
Many players experience that their current instrument (provided it is in good technical condition) often sounds better with lefreQue products than a more expensive instrument without. It is a very effective upgrade without a large investment.
