X ROCK.

pretty cool overdrive/dist...with just a tinker or 2 to the x fuzz...its pretty amazing what you can squeeze out of 2 trannies... :icon_twisted:



quicky clip..

edit: you can lose the 220k and 220pf too, and even lose 1 led, (the one with the negative to collector)..even smaller 8)

I see your recent adventures in automobiling haven't damaged your ability to shred too badly.

You can probably lose R1 too.

Alternativel you could try moving the gain pot to R3. For extra marks, you could try a Blues Breaker-style gain control with lug 1 connected to base, lug 2 to collector and lug 3 to C5.

hi sam, i'll give that blues breaker style a whirl.. 8)

i did try the gain pot as R3 but prefered it at the front...but i'll try that.

its a pretty cool little circuit, it has a good metally/rock feel to it for sure....sounds cool through my amp (clean channel) :icon_twisted:

Cool - I just re-read the thread and see that Gus suggested the Blues-Breaker style gain control too. It might tame it a little (or just break it).
I have just about finished the chorus, so will have some free breadboard space soon and will give it a try.

Oh - as drawn, your second (new) schematic has a typo - you have the a C-B short in Q2.

yeah give it a go man,  8)

the Q2 is fine, .. it wont work without that base/collector split  connection. just tried t to make sure.


 just tried the 'blues break' pot...yeah i find it better, more control at the front...goes from slight break to full on.. :icon_cool:

edit: forgot the 33k... ::)  sorted. ;)

Fair enough, but you still have a direct connection between C and B in Q2...

tinkering a little more

i found switching between the 1 led, or 2 1n4148's in series to be kinda cool too...different flavours.   8)

ok, back to breading..

this thing is fine, sounds great...not grate ;D

anyway, a little issue i have is with the pregain maxed i like to turn my guitar down to its minimum and have 'jangly' chord stuff going on...

however at guitar minimum there's a kind of gating (holding back) going on, ive tried tweaking the collector on Q1, to no avail...

and having a resistor stopping the pregain pot from going to zero...to no avail...(as per schemo above)

?

Have you tried a resistor from the gate of Q1 to ground?

yeah tried that too, even a lower gain trannie 3904....

this has got some lovely compression and sustain, even on a crappy single coil...very nice. 8)

but yeah the jangly part is eluding me...hmmmm....

yeah tried 100r's  and 220r's ....on both emitters...no joy,

and it takes the edge of it too....hmmmm...

i was playing with this yesterday with a crybaby in front, its really sweet, and the tone is nice and  'creamy' on neck and bridge  pups,''

and the wah when on/off lies in there seamlessly...really sweet. 8)

it has a kind of eric johnson type fluid feel to it  that just makes you want to fly all over the neck.....it really is that good imo.

i just want need to sort that guitar low volume holding back issue on it..

i stuck a SWTC on it just for now which is cool too...

@sam: do you have a breadboard spare?...be nice to get anothers opinion/test on this..

I'll bump it to the top of my list.

If it plays nice with a wah in front, then maybe you should try a buffer in front of the gain pot?
How does it compare to the Sptifire?

vero layout...something for the weekend.. ;)



oops left off the 100uf cap...like i say breadboard it first... ;)

I'm sorry... I didn't understand. The vero layout is wrong?
Somebody could post the correct layout for avoidin misunderstanding? Or adding an hint for correct it.

i just tried a bjt buffer in front but it buzzed like hell, and still gated when low...hmmm..must've done something wrong there i think.

i haven't got a spitfire here at the mo, its up my mates gaff...

got a buffer to try?..


@elijah,  breadboard the circuit first... or hold fire on it for now, as i was thinking of incorporating  XFUZZ/XROCK in one...eventually. ;)

What did you try?
I would have thought a simple emitter follower should do in this case.
