## Abstract

A stringed instrument including a housing defining an interior space, at least one string on the housing, an amplifier positioned in the interior space and attached to the housing and a pick-up on the housing and positioned adjacent to the string where the pick-up converts vibrations from the string into electrical signals and transmits the electrical signals to the amplifier. The stringed instrument includes an audio input on the housing and coupled to the amplifier, where the audio input is coupled to a digital music player and sound stored by the digital music player is coupled to the amplifier. At least one speaker is mounted in the housing and coupled to the amplifier. The amplifier converts electrical signals from the pick-up into live music and the speaker emits both the live music and the sound from the digital music player to enable a player to play along with the sound.

## Claims

### Claim 1

A stringed instrument comprising:
a housing defining an interior space;
at least one string on said housing;
an amplifier positioned in said interior space and attached to said housing;
a pick-up on said housing and positioned adjacent to said string and being constructed and arranged to convert vibrations from said string into electrical signals and transmit said electrical signals to said amplifier;
an audio input on said housing and coupled to said amplifier, said audio input being constructed and arranged to be coupled to a digital music player, whereby sound stored by the digital music player is coupled to said amplifier; and
at least one speaker mounted in said housing and coupled to said amplifier;
wherein said amplifier converts electrical signals from said pick-up into live music and the speaker emits both the live music and the sound from the digital music player to enable a player to play along with the sound.

### Claim 2 (depends on 1)

The stringed instrument of claim 1, which includes a plurality of pick-ups.

### Claim 3 (depends on 1)

The stringed instrument of claim 1, wherein said speaker is a built-in speaker.

### Claim 4 (depends on 1)

The stringed instrument of claim 1, which includes a plurality of speakers.

### Claim 5 (depends on 1)

The stringed instrument of claim 1, which includes at least one additional audio output for a headphone.

### Claim 6 (depends on 1)

The stringed instrument of claim 1, which includes at least one battery for providing electrical power to the instrument.

### Claim 7 (depends on 1)

The stringed instrument of claim 1, which includes at least one controller on said housing and coupled to said amplifier for controlling volume.

### Claim 8 (depends on 7)

The stringed instrument of claim 7, wherein said controller is constructed and arranged to further control at least one of: power on and power off.

### Claim 9 (depends on 1)

The stringed instrument of claim 1, which includes an adjustable bridge movably connected to said housing and positioned adjacent to said string.
