I am currently building a bass amp with 500 RMS watts from a class D power amp, four 10" woofers and an FET preamp input with a 10 megohm input Z. I plan to see if I can hear the difference with the FET input, vs a 1.5 megohm bootstrapped emitter follower vs a non bootstrapped emitter follower...

Wrong! Passive is 100-400 mv which is .1 to .4 volt and and be much lower if the input impedance of the amp is below 1 megohm. Active is amplified, has a much higher voltage output up to several volts and a lower output impedance which is not loaded down by a low impedance input on a poorly...

I bought a first shop order Fender of the legendary '62 P-Bass in February of 1962. It was made in September of 1961 and came with flatwound strings. It was the best playing bass I have ever put in my big mitts and had a tone that could not be matched. With original strings 40 years later it...
