Re: Alumitone Pickup Design Revealed

Thanks Bent. Are you sure it was 4.97 ohms, not 4970 or 4.97K ohms? As I'm sure you know, regular pickups are anywhere from about 7500 ohms to 17000 ohms or so. Without getting into too much electronics lets say you need something over 1 volt to drive the amp to a reasonable volume. To get that much...

Re: Alumitone Pickup Design Revealed

Bent....that's cool, lucky you! Can you do one thing? Just measure the ohms on the wires that comes out where you'd hook it to the guitar jack. It'd be interesting to know what you're actually feeding your amp with. Then we can guess how it gets from practically zero ohms from the one turn coil to h...

Re: Alumitone Pickup Design Revealed

Bent, You will find a lot of stuff on the site that Bay mentioned. I haven't read all the bits yet but what I was referring to was either a low to high(er) impedance transformer like in a low-z mike or...remember when transistor radios came out first there was a small audio transformer between the o...

Re: Alumitone Pickup Design Revealed

I think the "secret" is just a small transformer inside that transforms the really low impedance of the single turn coil (bar) into something a lot higher to couple to the amp. It would probably be similar to a tiny audio output transformer operating in reverse. Just my 2 cents worth.

Re: It's not a steel but check it out.

On the same subject sort of.... I was just looking on the SGF and someone in Switzerland is making pedal steels. The prices are way out of most folks range I think. S10 about $5800.00, S12 about $6800.00, D10 about $9400.00

I must be working for nothing!!

Re: Changer axle

Thanks Ray....now I see how it works. Looking through my scrap box I find some fingers I made like that one time. I kind of gave up on it though, couldn't seem to get the right places for the horizontal crossrods and the springs at the right tension for each string. Clever idea though. Those hex scr...

Re: Changer axle

Wow Ray.....I'm trying to figure this one out! I see where the string goes in and what direction it goes. Why would you have a slot for the finger to slide onto the shaft rather than just the hole. Then that one hole in the top piece must be a raise. In the hinged piece I only see holes in the sides...

Re: Pedal Stops

Just wondered what your opinions are on having adjustable pedal stops down at the pedals. I've just spent the day making pedals for stockpiling for whenever I get around to starting another guitar. I fell heir to a whole bunch of rectangular aluminum tubing and am thinking about using some to make a...

Re: Homemade Lathe

By heck Pat.....you're beatin' me at my own game. Nice lathe! Try to get yourself a variable speed motor. Sometimes you can find a used fitness treadmill on the side of the road...or somewhere. They have a SUPER strong DC variable speed motor on them. If you get one and rip it apart, make sure you s...
