Instructables Not like a BOSS distortion

[Mpsya]

Hi all

I recently came across this on Instructables.com and hoped someone might be able to draw up a layout for it. Sounds like it might be interesting!

The schematic is available via the link.

Very low part count other than all those knobs!

Cheers

I gotcha, working on it right now.

[Silver Blues]

Give that a look over, hopefully it's ok. Pot numbering may or may not be backwards.

EDIT Fixed.

[Mpsya]

Wow, that was incredibly quick!

Thank you so much. I'll get a parts order in and get it verified ASAP.

Thanks again, enormously appreciated!

[Silver Blues]

No worries  hopefully it's all good.

I might be confused, but could it be that you swapped collector and emitter of the transistors?

[Pivetta]

The ground connection on the L row is missing. I think the transistors are just reverse

[Silver Blues]

Yup you're both correct. I just did the transistors without checking the pinout of those specific models, I'll fix it.

[Kajnjaps]

Great work! Super fast too!

Has anyone made a sound sample of this by any chance? I'm really interested in this one but would like to hear it befor i build it. I Dont Mean any offense to anyone i just like to try and check them out first to see if it even fits my type of playing.I really really suck at guitar LOL

[glasspak73]

Also sorry forgot to ask.Do the transistors need to be matched to work correctly? Is this similar to  Tone Gods Finish Line?

[Silver Blues]

I have no idea but I would say they probably don't need to be matched.

[Mpsya]

I'm going to try and get it built over the weekend. I'll report back if I manage to get it finished.

[glasspak73]

I'm building it also today should be done tonight or tomorrow then i will start tweaking it.i might be able to make a short video for sound sample but it will be with my phone

[Kajnjaps]

Hi,

The transistors need not be (beta) paired, at least I didn't pair them. It isn't similar to the Tone God Finish Line.
I'd love to hear how it works out

[glasspak73]

I built it and still playing around with different transistors.so far i barely even get overdrive but no distortion or fuzz type sounds.Its probly the junk transistors i have.i love it stacked befor my English Muff'n it makes one hell of a solo booster.I'm still playing with it though i'll try to keep ya posted.

Hmmm  What type of transistors have you used?

[Mpsya]

I finally finished it over the weekend. I obviously don't have anything to compare it against but I believe it is working as it should.

I am getting a distortion with a fuzzy edge. There's not a great deal of distortion even when cranked but what there is sounds good to my ears. The bias pot changes the nature of the distortion (more splatty and fuzzy in several settings) with several 'dead' spots but I guess this is to be expected with this kind of control.

The shape knobs affect the signal quite dramatically depending on the bias setting and there's plenty of useable and not so useable sounds to be had. I tried swicthing out R1, 18 and 19 as suggested in the Madbean thread but found the stock values sounded best.

I have only had chance to play it at low volume and looking forward to getting it turned up!

Does it sound like a BOSS unit? No, and that's the point!

I think we can consider this one verified.

Thanks to Kajnjaps, Silver Blues and everyone else who has contributed.
