'SPITFIRE' Metal 'n' Blues Pedal...

then there
is an issue....

you only need to shield the input.

i shield from 3pdt to pcb only and its fine...

Ok now im getting somewhere.  thinking maybe these Merlins are not getting enough fuel.
The led i used was a 5mm 1.9v 20ma calculated 390 ohm resistance.
I used a 470 ohm resistor which is possibly taking away from PCB voltage?
Does the PCB need the full 9v to drive these Merlins?

[deadastronaut]

your led wont make any difference...

you should be getting 9v to the top 2 fets drains...

squealing came back with a vengeance. I noticed it is worse on modern mode. when i touch the soldered joint on back of pcb with my finger it stops.
the spot is in between c4 and c5 where the first gain wire is connected. Any thoughts? I'm thinking maybe my amateur soldering technique may be to blame.

squeal seams to almost disappear when tone is turned down past halfway mark. turn the tone up and it gets louder the brighter the tone gets.

hi benji, as soon as you mentioned making a pcb with a sharpie a red flag came up..hmmmm...

inventive sure , but a moody solution for a fully functioning long term use pedal  imo...

do you have any vero/strip board?...

if you have, and IF I get time i'll knock up a vero of the V3 for you ok.

I actually used the toner transfer method for the pcb.
I had alot of trouble getting photo paper removed. Not sure what brand it was, but after an hour of soaking I still did not want to come off. What I did with the sharpie was put 3 or 4 coats over toner just to be safe and to fatten the lines up for some added insurance. I will upload a pic when I get home. Can't seem to do it from phone.

ok...

Ok just want to post an image. what is easiest way to do this? Dropbox wants credit card info for 30 day trial. that's not happening so how do you guys get pics to show up on post?

[BoogiemanX]

butt ugly for my first PCB but it got the job done. lol

[BoogiemanX]

no etching sense i'm using a Hammond. Retro future look. there is an empty hole because i was going to have a second led and have them switch between modern and classic.

[BoogiemanX]

I think I might win first place for most wires exposed. looks like a birds nest.

[BoogiemanX]

I made this little adapter for a little more mobility while building the pedal.

[BoogiemanX]

works like a charm.

[BoogiemanX]

I think all the squealing was coming from my Zoom amp which might have a ground problem. I ran it through my Marshall 1/2 and it was relatively quiet. Only thing now is choosing which caps to use for tone.
when I turn the tone up past 1/2 way it gets so high that I might go deaf. When switching to Classic it seams to increase the volume slightly and give a tight lead solo'ish vibe which gives me an idea.
This could possibly be an all in 1 pedal. I'm thinking of building a second one in a bigger enclosure with a second 3dpt switch that will be to switch between rhythm and lead rather than modern and classic. just a thought.

[BoogiemanX]

Just one last thing to do. Welcome this little guy into the family.
My celebration is making me start to see double so thanks again Rob for an awsome pedal
I would also like to give thanks to my unofficial sponser "Bud Light" for making this post the challenge that it is
and Im gonna sign off before I go into a drunken rant that is completely off topic. lol

Photobucket, imgur.

Edit: DANG, you have already figured it out.

[deadastronaut]

i have free dropbox....dunno whats up with that..

anyway, so you got it sorted now then?...

[J0K3RX]

Might want to shield your gain pot as well, if you have not already.. Nice job on the sharpie etch
