Abstract: An exemplary modular musical instrument amplification system may comprise a chassis including a power supply, an input gain stage, a control processor and a plurality of modular slots. The modular slots are configured to receive any of a plurality of preamplifier modules for establishing an electrical communication therewith. The input gain stage has a modifiable response behavior and is in signal amplifying communication between at least one instrument input jack and the modular slots. The control processor is preferably in control communication between the modular slots and the input gain stage. Each preamplifier module has a respective input stage profile associated therewith. The control processor may be configured for sensing the input stage profile of a preamplifier module received in an active modular slot, and setting the response behavior based, at least in part, upon the respective input stage profile.

Abstract: A modular amplification system consisting of a plurality of pre-amplifying modules for allowing a user to select at will, a particular module as desired. The modular amplification system includes a chassis which houses a power supply for supplying low and high voltages to each of the pre-amplifying modules, support circuitry and interconnections for accessing the audio and control signals as required. Additionally, each of the pre-amplifying modules is designed, so that it contains the circuitry required for proper amplification of various musical instruments. The pre-amplifying module is selected from a vacuum tube amplifier, an analog and/or digital solid state amplifier, and analog or digital signal processing unit. The pre-amplifying module is then inserted into the chassis by an edge connector and suitable bolts which allows ease of installation and removal. Any combination of different pre-amplifying modules may be used which can then be selected by a user.
