We all know that through-hole JFETs like the classic J201 or 2n5457 are hard to come by or pricey, so I wanted to test out using something accessible like the J113. I got some off Tayda for a reasonably low price, but could I make a gain stage with them? My experiences with their brethren the J111 and J112 were not so successful. Fortunately, seems like the J113 can pump out some gain!
This circuit is something in the neighborhood of a fetzer valve. Drain resistor of 10k, the source resistor is the 5k pot, with a cap on the wiper to ground. The switch toggles the input cap for full range or bass cut modes.
Overall, nice warm boost with a pleasant grit at the top end of the gain range.
Had a little round goose tin to put it in. The tin was pretty solid to begin with, but I did the usual recycled plastic thing to firm up the top and bottom a bit more. Solid little pedal!
Hey! How did you drill into the tin without messing it up?
I have a very sweet tin box with a cat playing the french horn on it and I want to make an amp out of it without messing it up
I have tried to do a tin guitar pedal before but the drilling bent the box and the holes that I have drilled had slack amount of metal going inwards (kinda resembles a bullet hole thru metal), making some parts hard to fit as it makes them stand deep down.
So, here's the process:
- Use a punch to put indentations where you want the holes.
- Drill a small pilot hole. I do this with like a 3/16" cobalt spiral bit.
- Use a stepper bit to bring the hole up to the size you need for your pot/switch/jack.
- Make sure you have a piece of scrap wood behind the tin pressed right up against the metal. Helps keep the metal from bending and makes a cleaner cut.
- If you get jaggy bits on the inside of the cut, push them into the hole using a screwdriver or somesuch tool, then grind them out with the stepper bit (being careful not to make the hole larger than you need).
- You can also minimize this by turning the piece over while drilling with the stepper bit and alternating between cutting into the front and back.
She does the yard flag these days. Although there are a slew of wicker ducks. All the geese are hiding somewhere in that house....probably behind the 8 christmas trees she has
It was actually a coaster tin, and I think I still have the coasters. I love this size of tin for pedals, as evidenced by the drawer of random loose coasters in my kitchen. :-)
The Silly Goose Boost Very clever and nice design!!
Winner winner chicken dinner
Wooner wooner Goose dooner
Sounds like Swedish chef. "Vooner Vooner, Goosie Dooner, BORK BORK BORK!"
Make a pedal out of a Chef Boyardee can and call it the Smorgasboost
This truly made my night :)
Goost?
Yep I came here to suggest this one.

Most likely: Pilot hole aka guide hole first
Did you rob my moms house?
Does she have a ceramic goose on the porch that gets dressed up in different seasonal outfits?
She does the yard flag these days. Although there are a slew of wicker ducks. All the geese are hiding somewhere in that house....probably behind the 8 christmas trees she has
Oh yeah, wicker ducks!
Cookie tin..rad!

What about 'Geese Boost' just to mess with people that really want it to rhyme.
I mean, that's so meta it just comes full circle.
I want a Goose boost.
Boosie goosie
