From the project

JFET ОУ для электрогитары, для согласование высокоомной нагрузки и предусилителя. На входе есть хамбакер и нэк, есть переключатель для отключения одного или другого звукоснимателя, из питания желательно на 1S аккумуляторе. А так же пассивный jeck для отключения схемы с предусилителем и , чтобы можно было воткнуть гитару прямо в гитарпроцессор.

ПРЕДУСИЛИТЕЛЬ ДЛЯ ГИТАРЫ: буфер + 2-полосный темброблок, 1S Li-ion, громкость B500K push-pull (актив/пассив), светодиод питания =============================================================================
