The support is of the type that includes at least a base body provided with an attachment to a stringed musical instrument and a support for supporting and attaching the pickup to the base body. The attachment includes at least a fastener which is movable by an actuator which is rigidly connected to the fastener, the ends of which are configured to project in part through respective holes arranged on the outer surface of the base body and attached to the stringed musical instrument. The base body also includes at least a retainer for the fastener in the attachment to the stringed musical instrument. ## Claims ### Claim 1 An interchangeable pickup support for a stringed musical instrument comprising: a base body configured to support a pickup for a stringed musical instrument, said base body comprising at least two openings on an outer surface thereof, a fastener having an elongated body and comprising at least two projection sections and two through holes to maneuver the fastener, and a source of pressure configured to apply pressure to the fastener, wherein the base body comprises a space in an interior thereof to accommodate the fastener, and the fastener is configured to be movable such that the at least two projection sections project in part through the respective openings of the base body to engage with a body of the stringed musical instrument directly or indirectly and that the at least two projection sections retract to disengage with the body of the stringed musical instrument. ### Claim 2 (depends on 1) The interchangeable pickup support according to claim 1, wherein the at least two projection sections are symmetrical. ### Claim 3 (depends on 1) The interchangeable pickup support according to claim 1, wherein the base body comprises four openings and the fastener comprises four symmetrical projection sections configured to project in part through the respective four openings arranged on the outer surface of said base body. ### Claim 4 (depends on 1) The interchangeable pickup support according to claim 1, wherein the fastener is movable in a radial direction relative to a midpoint thereof. ### Claim 5 (depends on 1) The interchangeable pickup support according to claim 1, wherein the two through holes are arranged on either side of a midpoint of the fastener, allowing the fastener to be manoeuvred by the action of two fingers of the user. ### Claim 6 (depends on 1) The interchangeable pickup support according to claim 1, wherein the source of pressure comprises two helical springs which are arranged vertically on the fastener and apply pressure to said fastener against the base body. ### Claim 7 (depends on 1) The interchangeable pickup support according to claim 1, wherein the fastener is a planar and the at least two projection sections have a partially sloping termination. ### Claim 8 (depends on 1) A stringed musical instrument, comprising an interchangeable pickup support according to claim 1. ### Claim 9 (depends on 8) A stringed musical instrument according to claim 8, wherein the instrument is an electric guitar.
