All instruments produce a pitch.
The instrument like any wind instrument produces sound by vibration. The tone produced does not naturally change in pitch the Vibrato effect is created by moving the instrument against the lip lightly or moving the jaw producing a wah-wah effect.
A percussion instrument with no pitch is (obviously) a percussion instrument, but with no recognisable note in any scale, producing a beat rather than a note. Examples of these instruments are snare drum, bass drum, tomtom drum etc.

An instrument that has a pitch lower than a flute is the clarinet. The clarinet typically plays in a lower register, producing deeper and richer tones compared to the higher-pitched flute. Other examples include the saxophone and the oboe, both of which also have lower pitches than the flute.
The flute is a C pitch instrument.

You can easily change the pitch of an instrument by the embouchure you are making with the instrument or perhaps even make an adjustment on your instrument. If it is flat, you must pull out your instrument, if it is sharp, you must pull it in.

Pitch refers to the highness or lowness of a sound, determined by the frequency of the sound waves. Tone, on the other hand, refers to the quality or timbre of the sound, which is influenced by factors such as the instrument or voice producing the sound.
A pitch box is an electronic device that inputs a signal from a musical instrument such as an electronic guitar, distorts that signal, and then mixes the input with the distorted signal to produce an output. Typically the pitch box is capable of producing a variety of types of distortions. To hear what's possible you might try searching youtube.com for pitch box.
