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

[mr_deadmaxxx]

can i use spitfire as a preamp for a diy solid state amp? 
would this be able to emulate some tube-like sounds?
or respond to picking intensity?

thanks..

[deadastronaut]

i don't see why not.. ...it sounds great through an amp/cab..more ballsy

i was going to build a SIMPLE small amp (for camping) with the spit in it...you may want to explore tonestacks if your going to build it in an amp though..

while i'm here ,ive been looking at cab sims with jokerx, but so far haven't got it to work..

maybe someone with more knowledge could chime in on that...anyone?..

[mr_deadmaxxx]

another preamp? or works like a power amp?
would it be better as a closed cab? or an open one? 

[deadastronaut]

spit----then clean amp...just like normal pedal-amp

not sure on the cab question, depends on a lot of variables....

you can always stick a removable panel on the back and have both..

Hi i like Spitfire, the name really suits it. Can u post schematic pls?

[deadastronaut]

in my gallery...

also a pcb and layout pdf's ok...for the v3.

have fun.

[JebemMajke]

Cool, thnx. I suck when it comes to reading layouts, i get easily lost there. Is there a big difference between v3 and v5?

[deadastronaut]

v3 is the bog standard good all rounder..

v5 has more bells n whistles..fuzz/tone caps switching...

breadboard it and try em out...see if you like it..

i use the v3 all the time now...can be subtle, to heavy with just your volume....

How it reacts with guitar volume/strings/harder picks/picking?

How it reacts with guitar volume/strings/harder picks/picking?

its good...check out the demo of volume on guitar lowered...its got good tonal character...

ive been playing 32 years and its fine for vaious styles..heavy blues/metal etc etc.....on this pedal i had it switching between 4.7 and 6.8 caps..

on the one i have now its 3.3 and 6.8... the 3.3 just tightens up the metal mode more...

demo is not through an amp, just a mixer ok...bear that in mind.......i'll do an amp demo one day...

Ok, I will check it out.
Btw here are some speaker simulators, it's a Russian site, but still electronics are the same no matter the language.

cheers man, i'll check those out...thanks a lot!...

I'm finding the the by-pass caps can be smaller than usual to reduce bass and in effect get more treble.  100n to 470n are cool. 

I'm going to stick an SHO in front or maybe the middle and reduce the gain elsewhere.   

Has anyone tried replacing the 2.2k source resistors to ground with GE or SI diodes.  I'm interested in what you think.

Don - Phil. - Just fyi, I use the Spitfire v3 as a preamp all the time and in my opinion it is where it really shines!!! I have used it running right into my B.K. Butler MosValve power amp and it sounds insanely good!!! From the pedal I run into a delay pedal into a stereo chorus pedal then splits into stereo into the right and left channels of the power amp then runs into a 4x12 cab that I wired for stereo. The high end of the tone knob that has somewhat too much treble is totally usable in this setup! Sounds like the a hot rodded Marshall - Brown Sound early VanHalen I,II sound! Really good tube sound, better than most actual tube amps! I also run it direct into my DAW and I use Marshall - Celestion G12M 25 watt Greenbacks 8 Ohm 4x12 Cab impulses.... Sounds amazing!!! So, yeah you can absolutely use it as a preamp!  The only thing that I wish was different is the tone stack... needs a bass/mid/treble stack for better preamp type tone shaping.. not a real big deal but would be nice and not something I have seen in hardly any BSIAB variants...

Edit: I have also run it into the FX return of my brothers 5150 II thus bypassing the amps preamp and going into the power section of the amp... Guess what? Killer!!!  

Edit Again: Damn Rob, we gotta get a good cab sim for this thing!!!

[deadastronaut]

@wgtp: i'll give those diodes a go today.... and report back ok...

@jim: sounds like a good setup you have going there....nice!...

ive tried a few stacks on it, but it tends to lose its 'thick' tubey character when replacing the original tone....(which i worked on for ages)

a full stack is going to need more than a few tweaks in the tsc or other stacks ive tried to get that the same and adjustable........we'll get there in the end i'm sure!...


@wgtp: any ideas on splitting the tone control into its seperate BMT parts freq wise?....mr tonemeister .....that'd be cool...

Craig Anderton's super tone control can do that. Tried and proven circuit, very versatile, also has adjustable freq and resonance. Capable of very good results.

[deadastronaut]

^ looks cool...have you built that?..

hey, thanks for sharing man..

about the tonestack, this could work perhaps..
the one in "0p" is actually "10p" and the ICs are Dual Opamps.

[WGTP]

I'm not aware of anything new and wonderful with passive circuits.  There is the standard Fender, Marshal and Vox stacks modeled with the Duncan Tone Stack or the Baxandall which might be good to have if your already using the standard ones in your amp.  Some people "scale" them for less resistance.  ROG has a couple of interesting things.  The one above looks good.  You almost have to go active to get very "detailed" tone control. 

[deadastronaut]

hmmm...so that tonestack above needs a voltage divider...say 9v-100k-100k-ground ...

and between the 100ks connected to the 1/2 v's...

i take it the freq is a dual 47k pot...or is it best as 2 seperate 47k's..?..just curious..

best on 2 opamps rather than a quad too i guess...


:don:  wtf is that avatar?...
