![]() ![]() thus my vol pot can be 10k or 25k, reducing noise and allowing a passive EQ using reasonable Zin, to follow it. Ive tried to move away from electric guitars that require batteries. Ive seen the Eric Clapton pre amps on sale on eBay. this will give me a Zout (R4 in your schematic) of 5.3k according to the Fetzer calc. The EMG afterburner gives you all of the advantages of a preamp plus boost in one easy to wire control. Trying to insert a passive EQ circuit after the vol pot now.Īlthough the 2N4117 uses VERY low battery power i am thinking of using an NTE457 (Vp 1.26, Idss 1.09mA) instead. I am thinking 6-12dB of gain upfront should be plenty.įetzer Valve Revisited at the bottom of the page has a Rd and Rs FET resistor calculator that I was blindly following. EQ with mid boost & cut, LPF & HPF -this is another circuit and another topic, not sure active or passive final Zout of the circuit <1k - to interface with a console/audio interface ![]() passive & active use of the Strat via push/pull pot, active out is in phase with passive ![]()
