From the ever-prolific one-man operation at PCB Grinder comes a modified, and highly functional take on the classic FET compressor design. It adds a “Dirt” control, longer attack times, and uses an IC-based input stage rather than a transformer (retaining a Lundahl 5402 as an output transformer). The kit includes all components needed, with the exception of a power toroid and enclosure.

FET Grinder Features:

• Control layout mirrors original, with added “Dirt” control
• NE5532-based input stage, Lundahl 5402 transformer-based output stage
• Simplified design for an easier build

Price:

• n/a
