I'm wondering if anyone can help me.
I'm a bass player and sometimes on stage I need to use a microphone

for background vocals.
I need a circuit that turns my AKG C1000 microphone on and off when I want it, without the intervention of the FOH operator

.
I prefer the connection to be made by footswitch, placed on the floor near the microphone stand.
The Noise Gate is not suitable for this service due to the sound pressure variations that appear on stage.
Moreover, there is a problem

: A condenser microphone takes a few seconds to be prepared to respond, if it is turned on for a particular moment. This makes the on/off operations via the microphone's own switch not suitable for the required speed.
Therefore, the powering circuit of the microphone itself must be PERMANENTLY in operation, and the circuit I need must act directly on the balanced audio output (mute).
I have researched this subject and i found this but the asked price is quite higher for something apparently simple.

Does anyone know of a simple, low-noise, transistorized cheap circuit that simply turns a condenser microphone (phantom power P48) IMMEDIATELY on and IMMEDIATELY off, for balanced microphones that are switched over and without making any noise at the FOH when switched?
Sorry for my poor english and thanks in advance
