The present exemplary embodiments proposes a vacuum tube amplifier module which removes a noise caused by external shock or vibration, including a vacuum tube amplifier which includes an amplifier in a vacuum tube to increase an energy of an input signal to output the energy as an output signal, an assembly unit which fixes at least one side of the vacuum tube amplifier so as to primarily remove the noise, and a magnet which is assembled in the assembly unit to levitate the amplifier so as to secondarily remove the noise to make the noise a predetermined reference value or lower.

One or more embodiments of a device for securing guitar modulators is shown. The device includes a face, a bracket, and a base. The face defines a hole that extends completely through the face with a first length in a first direction and a first width in a second direction perpendicular to the first direction, wherein the first length is greater than the first width. The bracket connects under the face and extends in the first direction parallel to the hole and is configured to allow a grommet to slide along the bracket in the first direction. The base is configured to support the face.

The embodiments herein provide a system and method for instantly switching sound pickups in an electric guitar using a spin wheel arrangement in the middle of a song. The spin wheel houses a pickup assembly with multiple pickups. The spin wheel allows a guitar player to easily roll neck pickup to bridge position and bridge pickup to neck position in middle of a song by rotating the spin wheel. A click stop arrangement halts wheel rotation after completing a semi-circular rotation around a center screw. The backend portion of pickups is connected to spring loaded plunger. The contact pads at bottom portion of guitar body establishes electrical connections between pickups and control components. The pickups under the strings get activated. The spin wheel arrangement allows a guitar player to add favorite pickups for generating various tonalities beyond the limit of a single guitar.
