Modified Little Green Wonder

hahafender
is there a way to take out the body pot and set the resistance that goes to it at around 12 o clock (whatever value that ends up being) and then adding a tone pot? and eventually maybe adding a clipping section for the LEDs and the appropriate diodes

would be awesome to get this running :D

thanks!

I'd probably do it on a daughterboard because altering the layout to add resistors will make it over 21 columns and so make it unsuitable for a 1590B.  On a small daughterboard you could include the two resistors, or even better a couple of trimmers so you still have total control but internal.  Then you could also add the different clipping options you want.  For a tone control you could just tack a SWTC at the end, in between the Volume 3 wire and the volume pot.  Like these

You'd just need to again experiment with values to get the response that works with your gear/ear.

hey thanks mark... i have a couple ideas... can you email me the layout file so i can edit it? dann-gonzalez@hotmail.com

thanks

also... what pair of diodes would you recommend with the green LEDs?

Try something like this.  Personally I'd go with the trimmers



Use your favourite diodes for the other clippers, 1N4148, 1N4001, schottky, germanium, or whatever

hmm... interesting thought. here's what i was thinking:
omitting body pot A. Move the far left 1uf cap to the left and put a 10k resister from that rail to ground. (standing a little bit, ah well) (was also going to socket that resister to see what i'd like best)
For the tone control... I was going to swap the 47n cap and 470r resistor(that'll be standing a bit). (47n cap -> 470R -> ground) Connect lug 1 of a 20k lin pot to pin 5, lug 2 to the 47n cap, and lug 3 to pin 6... forming a classic TS tone control -- For the board: Take the wire labeled "Body B 1 & 3" to Body B 2, then run wires from the strips going to pins 5 & 6 to Body B 1 and Body B 3, respectively.
As far as clipping, in my head, i was going to take wires coming out of the positive sides where the LEDs would be, to the center poles of a dpdt. then two green LEDs on one side, and 2 other diodes on the other.


What do you think about this idea?

just realized also, with that idea... it's tricky to take that 47n cap to ground. dunno how i would go about doing that one

excuse me, the 470r resister*... not the cap
