Re: Can someone please explain inductance to me in simple terms? You know, you are absolutely right! me bad. if pickups had a Z of 75 ohms, you could drive miles of cable, this might be one of the reasons Les Paul invented the recording LP. here is a graph showing that indeed, at frequencies...

Re: Can someone please explain inductance to me in simple terms? Hi Dave! A simple bottom line answer to your question is increased inductance means more bass. And probably more output, depending on magnet strength. Of course this is a generalization as there are other factors involved. I am...

Re: Can someone please explain inductance to me in simple terms? And finally the formula for capacitance for all the layers> Note: Cc must be derived from the previous page.

Re: Can someone please explain inductance to me in simple terms? And another look at this from Col. McLymans book which probably has the most workable equations. Note: MLT stands for Mean Length Turn which is the average length of all the turns of the pickup, example - inner turns are 5...

Re: Can someone please explain inductance to me in simple terms? Don't like solving integrals that much, (forgot how!) so there are other approaches that do not involve calculus. Note fig. C in the drawing. This is a winding techniques used for example in the UTC A-10 mic input transformer...

Re: Can someone please explain inductance to me in simple terms? Fishman? I believe it. If they are using more turns than an electric pickup, then capacitance will start to be a real problem. They probably want to preserve the high end of the guitar, and harmonics can go way above the...

Re: Can someone please explain inductance to me in simple terms? Here is a page out of RDH4 (Radio Designers Handbook Version 4) on sectioning. Note that you can simulate this section process while winding a pickup, instead of going back and forth with your winding machine, you build up "pies"...

Re: Can someone please explain inductance to me in simple terms? Pico is right, I made it sound like using tape was as good as sectioning and that is incorrect and for that, i apologize. There are two different things going on in that post, sectioning, and using tape to increase the distance...

Re: Can someone please explain inductance to me in simple terms? another way to tweak response, use tape. this is a trick we picked up from a Telefunken V72 preamp from the 50s. the plate chokes have 21,000 turns, this causes excess capacitance, so they use a three chamber bobbin and tape...

Re: Just bought an Alnico 6 bar mag and an Alnico 3 bar to put into a set of Custom S sounds like you have some extra magnets on your hands, why not double up? there is room underneath, gonna need some glue because it takes force to hold the polarity right, double your mag field, double your...

Re: Can someone please explain inductance to me in simple terms? my friend Doc Hoyer sent me a piece of old school wax, Doc winds coils for MacIntosh and Marantz up in Wisconsin. all of your old classic vintage audio transformers used this stuff. here is what it looks like, it has a higher...

Re: Can someone please explain inductance to me in simple terms? We did some inductance tests on a freshly wound humbucker, trying for the Pearly Gates DCR, which is 8.3 K bridge IIRC. Ended up with 5146 T on the slug coil and 5200 T on the screw coil, both #42 AWG. Had to use a little...

Re: 40-50w tube head suggestions for club gigs. You might look into a Kustom 72 Coupe. They were designed by the 5150 guy, James Brown, after he left Peavey. Wonderful sounding amps but music is subjective so your mileage may vary.

After rewinding a few pickups I have noticed some funny things while checking the DC resistance of the coils. These same things I first noticed while winding transformers. If I wind a transformer coil and check the DCR, I get one reading. After installing the coil onto the steel transformer...

Re: Can someone please explain inductance to me in simple terms? Cool info, Thanks! Here is a graph we just completed of a single 5000 turn coil wound with #42 wire. We measured inductance by attaching a signal generator to the coil and measuring the current into the coil while keeping the...
