Not really sure what happened to this thread but I was falling asleep in class this morning and this kept me awake for a bit.

stop falling asleep, you'll miss the tayda coupon.. ;)

cool,  ive been messing with distortions again, i'll give that a whirl..

i do have a rough though not perfect thing on a bb at the mo...tweaky tweak..

i just fancied having something simple i could use to go straight into DI/MIXER...for late night stuff...tame the highs, and boost the lows..not a cab sim per se', etc etc...

well after trying almost every cab sim out there, and not being at all happy

with any of them, i came up with this last night... :icon_idea:

unorthadox but it works pretty well,

the pot acts as a kind of ''air'' freq setting...like moving the mic around a speaker cone

well it does to me anyway ::)...thats the best way i can explain it..



here's a clip ,

signal:  guitar -- distortion, --cab sim on/off,

direct into mixer...(which was the aim.) i turn the 'air' pot gradually towards the end...

its also nice on clean too.... 8)

stick it on ya breadboard and try it with your dirt.. 8)

Might be sooner though... ;)

just for rich i added biasing,

so theres a 47uf, and 2x 10ks...

470k at pin3, and 470k at pin5 to vb ok....

im pretty happy with it,  i,ll be trying a multi fx distortions later, ( without internal cab sims)

And see how this compares.....sounds cool with my distortions,  so we,ll see how it fares with standard
factory dirts...

cheers johan,

but ive tried a few of those too...believe me, ive tried lots, passive, active...to no avail.

i'm kind of almost there with this one i think, i tried other distortions through it earlier

and its pretty cool....

I got a few minutes and threw this together, Rob...sounds a lot better than just line in!  And simple.

1 question - is a touch of distortion normal in the background when playing (clean, no pedal)?  That 2nd stage gain is about maxxed, so I would assume it's not a totally clean thing, or that maybe a pot on the 2nd stage could be used to dial back the 'gain'.  You probably don't notice a thing if using a dirt pedal ;)   Low battery too, which can't help.


Edit:  Yup, popped a 50k pot in Rf position of U2 rather than the 1Meg fixed.  That fixed the overdrive issue, so a knob is going there, perhaps 100k or 250k.  This sounds very good  for clean too!  Played some Clapton Strat stuff like Lay Down Sally into my sound card, and it was very presentable   :icon_cool:

That sounds pretty good Rob! Kinda reminds me of the Stoned Tone Bulldog..
Doesn't matter what you did to get it... If it sounds good, then it is good!

Hi mike, great, glad you tried it,   8)

i had a bit of dist on it, and it kind  of locked up on power down , but when i added the bias it sorted that out... .

Yep its very nice on clean ,  lifts it too....

and yep a smaller R is better.....i just threw what i had to hand on it....


jim, give it a whirl man....i think youll like this,...loves a high gainer.  :icon_twisted:

Yup, really cool with massive distortion too, LOL! 

I like the filter, it gives you quite a big range of sounds for such a simple thing.

cool...yeah i like that filter too...very cool.

been getting a bit of clipping on clean, (humbucker bridge)

even when dropping value of IC2 FR....hmmmmm.....tinker tinker...

also when hit hard with filter turn up full, goes into screaming, only on clean..
i put a 33k before pot, seems to have tamed that....


edit, trying a similar filter on ic2.... ;)

Mine shrieked like a b@stard at first...I increased the 47p to 68p and decreased 2nd stage's gain...but I'm not discounting the effect of my cheap BB, which must have really odd capacitances.    Thing is unshielded in any way, too, which is bad.
