Charley Wirz installed three Danelectro "lipstick tube" pickups, and wired it using his own custom, non-Fender configuration. What was the pickup wiring diagram configuration? Was the volume pot 500K like a danelectro guitar? I read that a 500k volume pot can make fender stock pickup sound...

I brought a new Fender Squier Vintage Modified Stratocaster Surf Electric GuitarDuncan Designed LS-102 for Strat tube-style single-coil neck, middle and bridge pickups My Question is that the pickups don't have any jangle at all, they sound like regular stock fender strat pickups , whats the...

When i turn my strat volume pot down it creates a THIN sound but the amplitude is very low How can i modify my strat so when i turn down the volume pot it creates this THIN sound but the amplitude is loud like on vol.`10??

SAG mods what kind of SAG mods is there to put in a fender or marshall plexi? Where do i put the SAG mods at in the amp?

1.) Having all the power tubes have individual bias trims 2.) Have a Half power switch to turn off 2 power tubes 3.) Plexi mode switch to a JMP mode switch 4.) Randy Rhodes cascading preamp 5.) Power supply MODs a.) Low capacitance- more looser sound b.) High capacitance- more tighter sound...

What are some basic tricks or tips about adding more gain in a fender or marshall in each preamp stage or section?

Whats the difference between a PLEXI VS JMP? The preamp section, cathode follower circuit, tone stack, output stage looks the same to me Is the plexi output transformer different than a JMP transformer how and why? what else is a big difference between the two designs?

Randy Rhodes 1959 JMP cascade preamp? Randy Rhodes used a 1959 JMP What does this cascade preamp mod was this? 12AX7 has 2 sections inside the tube right? Did Randy Rhodes just put them in series? is this what cascade means?

What are grid stoppers resistors and screen senser resistors do?

When looking at fender and marshall schematics i always see a voltage follower circuit before a tone circuit why is that? What else are voltage followers circuits used for?

How do u set the duty cycle of a square wave? so the positive has a different pulse width than the negative? I have seen different amps marshal,orange,hiwatt, etc. have different duty cycles on there square waves How do they set them up ? What changes the pulse width of the positive cycle in...

1.) what happens when you but DC offset on the cathode or input of a 12AX7 preamp tube? 2.) It seems the "frequency responses" changes when you have DC offset on the input pin on a 12AX7 preamp tube so why that?

I notice these different waveshapes and waveform symmetry on varioius amp stages 1.) When the positive cycle clips before the negative cycle, what is this called and what would be causing this? 2.) What causes the positive cycle (sine wave) to be clipped and having a slope/ramp at the top at...

1.) Whats the difference between a 6L6 transformer VS EL34 transformer? 2.) I noticed my "presence" parameters peaks,notches,crossover points change with different transformers used why is that?

I have seen different amps with different Biasing capacitors and filtering some are 10uf or 20uf or 50uf and then 150uf has alot of time constant, its takes along time to stablize the DC voltage but filters out the noise and ripple The biasing block diagram is : 1.) Transformer tapped at...
