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

[Jorge_S]

Rob, can you tell us which kind of capacitors you used for the pedal at the demo? which ones ceramic, film, poly...?

Awesome Video! (both the playing and the video production - you must have some nice software toys)

How about a gut shot?

@walt,  i used a mix of windows movie maker, and sony vegas pro for the logo space stuff...nice toys indeed..

heres the best i can do at the mo for an intestinal shot.....i hate gut shots, its tantamount to having to do games (P.E)  in your under pants at school.....

i used a mix of mono ceramic, ceramic's on this one...the next one i build will be film's etc....just as a personal experiment in 'differences' ,if any, in sound...

not the neatest of wiring, but i had a lot of human+feline interference at the time...

@walt: recognize that 1uf?...

@steve H . do a masters degree in pedals!!!

Here is mine!

Tried something new. First sanding 120/300. Then spraying with a photo positive liquid, this one:

Then etching with HCL 30%, H2O2 30% and water (1:1:1).

Thin lines got a little bit too thick, next time I cover the thin lines with a liquid frisket, this one:

Etching took ca 10 min...
This weekend I do the soldering, hope it sounds good

Here's some guts for ya...

[deadastronaut]

@maik..  whooohoooo came out great man!...so that stuff worked fine!....cool...

one tip though...don't spray the paint in...dab it in by hand, so you don't fill any pits....looks great!...love those little mushrooms!.. and the duck!


@jok3rx: that looks the nuts man!....very tidy indeed.!...love the black pcb, nice touch!...it'll make it sound meaner too...

[Maik]

Thanks Rob.
Will do the paint with a brush.
And jip, the psylowichtel are great...

[deadastronaut]

@maik: ha ha...are you putting 3mm led 'eyes' in for on/off....or 5mm led in the gun hole?.....

and whats that in the ashtray?...tut tut...!!...

[Maik]

@ Rob: hupsi, wrong photo  

No LED-Plexiglass between box and bottom as a footlight with a red LED like this one

Post Nr 9. This is how it will look, but in red

[deadastronaut]

cool,yeah i like those, ive done a few too....

i'd be tempted to do the eyes though too...just for eye candy!...

but i am addicted to leds...

Check out this new ROG project called Ginger.  Notice the placement of LED's to prevent "hard" clipping of the Jfets.  I have placed 2 red ones between distortion stages and it has a nice affect, slightly altering the distortion character.  I bring it to your attention for that reason, but also the LEDs BLINK, getting brighter the harder you play and going dark when not playing.

The PCB arrived and I built it up on the table (meaning its not in a box yet). Very impressed, close to tube-like sound IMO, but different also.

I built the V3 sticking as close as possible to the spec'd parts using parts on hand. The tone control is a bit touchy but there is a sweet spot there for me. It made me keep playing. I think it needs a few hours to sound right, because it seems to get better and better with use.

One thing I did was put sockets in for the JFET's and found the 2N5457 to be a bit warmer in the lower position of each gain stage (Q1 and Q4 on the V3 pdf layout). I love it. I used 10n and 4n7 for the switch, it works great, both positions are good and useful. This circuit has heaps of gain if required.

For some reason the neck humbucker sounds a bit single coilish with this circuit, no idea why, but I like it. The 470pF bright capacitor on the gain pot got pulled in the first 5 minutes, just a bit too bright for me, sounds good without it.

I really like this one and it will probably become my #1 dirt pedal. It is unusual in that a lot of original tone from the guitar seems to be preserved rather than mashed up. 10 out of 10 Rob!

@ian: great stuff man, 

yeah its good to mess with the fets, and the tone caps too...anywhere from 2.2n to 10 is great...tight to open..

and yeah even on my ibanez humbucker neck pup, its got that woody fenderesque sound...i love that too...goes from metal to funky-hendrixy slappy stuff....lovely tone!...

really nice....and still like you say preseves the guitars sound as well...its my #1 dirt for sure.....

i fancy i'll have a dig at the dr boogey next, ive built a few but never liked the tone controls on it...but at the end of the day, i like this best!!!...more versatile, i also love the way it cleans up

with the  guitar volume...great with a swell/volume pedal....

i look forward to seeing/hearing your build man...

The 470pF bright capacitor on the gain pot got pulled in the first 5 minutes, just a bit too bright for me, sounds good without it.

Jumper or just pulled?

[deadastronaut]

either i guess...

i just built another spitty, but i dropped my 'modern' cap 4.7n...to a 3.3n....makes it a little tighter for riffin...

[deadastronaut]

whoops sorry maik,  pull it and jumper it....

[Ronan]

I just removed it, no jumper, since my bridge pickup is fairly high output, and I don't use full metal-type gains, so maybe that's why I noticed the brightness at low gain settings. If you don't use lower gain settings, you wouldn't hear the bright cap.

If you put a jumper in there where the 470p cap was, that would give a different sound again, I don't know what though.

Will try to get a sound clip going this Friday, any suggestions on where to host it?

[deadastronaut]

hi ian, use 'dropbox', its really easy to use...drag n drop...copy link..paste...and free..

[Maik]

Parts arrived, so I will let the 470pF inside and if it's sound boring  I pull it out...
