i'm going to build a breadboard testing rig.
i caught the building bug with my amp (1W self split (12AU7) FireFly)
building pedals will feed my addiction at a fraction of the cost of building amps 

when it comes time to build i'll prolly go the Vero rout to make modding easier.

your right, for $1 i'm just going to use the pump to make it simple and compatible.

thanks for the advice and warm welcome Jacob

i'm going to make the Ver. 2.0 for now. don't need the buffer/higher output.
besides i enjoy soldering, so i prolly make a ver. 3.0 later on.

i'm going to hold off on the enclosure until i see how big my layout will be.
what are my options besides etching a board?

would it be possible to skip the pump and wire the pedal for a 18V input?
if not i'll order the TC7660SCPA.

C2? the PDF talked of switching C3 around for different tone filtering
i dig the experimentation aspect. i pulled my .0022uF coupling capacitor
in my amp and kept doubling the value until i settled on a .022uF.
what a difference!

thanks so much for the help  Jacob

nice. i did search but didn't find that. thanks a lot.  

[edit] i'm locking this thread. follow ver. 3 discussions here.

thanks again ckim715

do you have a link or source?
not worried about the PCB but more about the circuit components.

thank you

hey Brian,

i'm itching to build a FatPants pedal. my cart is full (.ver 2) but i noticed you have a new version coming.
just wondering what's new in the 2012 version.

many thanks for all your hard work for us tone seekers

as long as your getting the voltages you desire and aren't overloading anything. 
wish i could be more help.

i want pics when you start building this bad boy.

have you checked http://www.mouser.com ?
they seem to have good prices, and a sweet filtering system to find what your looking for.

i like the feel of CTS pots. Alpha is good quality but they turn to easily for my tastes.

110V? where do you live? here in the US we get 120V out of those holy thingies in the wall. 
running 110V trannys @ 120V will give you more than you need/want. *cough Fender reissues *cough

just a friendly heads up. good luck with your quest

hello everyone

this is my first pedal build. i'm going with the FatPants.

PCB isn't available. What do you recommend?
i'm going with Xicon 1/4W metal film resistors.
C2/C3 Panasonic ECQ-V1H223JL?
C4 ECQ-V1H104JL?
512-J201D27Z good for the transistor?
Bourns 3362P-1-503LF trim pot?
Volume 16mm 100kB Potentiometer (linear taper?)
Fat 16mm 10kB Potentiometer (linear taper?)

i can get everything above from mouser.
not sure which enclosure to get and where from.
was going to ask about switching but i don't think i'll ever turn it off  

TC1044SCPA is back ordered can i wire without it @18v?

C3 is calling for a 22nF (0.022uF) which is what my amp has for coupling.
would going to a higher value (double) make a difference?
i'm thinking of putting in a socket so i can switch caps out.
or possibly run two parallel with a switch on one.

thanks for reading
