Supermagnum/double-gain
A small PCB that uses two TL082BCP op amps to amplify a signal from a contact microphone.

The TL082BCP is a FET Input Amplifier made by Texas Instruments in a PDIP-8 package with 8 pins. -20V~-2.25V、2.25V~20V 0℃~+70℃ 100pA 105dB 18nV/√Hz@1kHz 1mV 1pA 2 20V/us 2uV/℃ 4.5V~40V 5.25MHz 960uA Short-Circuit Protection、EMI filtering/RF suppression PDIP-8 FET Input Amplifiers ROHS.
PCBKit's library has its KiCad symbol (Amplifier_Operational:TL082, from KiCad's library) and its footprint (Package_DIP:DIP-8_W8.89mm_SMDSocket_LongPads, from KiCad's library), ready for a KiCad board. 919 are in stock at JLCPCB (part C1346226). 1 open-source board in 1 repository on GitHub use it.
