I built it on mark m's layout, just folowing the schematics. Is this normal? When I tried other versions,, it didn't have so much bass.
try this
C2 22n or/ and
C1 10n and /or
c8 47n or/ and
c11 100n
1 and 2 are pre saturation filters and 8 and 11 post
Hmmm... Multilayer Ceramics... Based on my experience, those caps give you a darker tone as compared to metal films, which produces more brightness and crisp sound. I wonder why Fuller used this type of cap.sinner wrote:I know it's traced, but maby some of you would like to have it, it is v4

Quick question, I built the Vero per the layout and I am getting a wierd effect when the gain is cranked past about 3 o'clock. With the gain cranked, the signal cuts in and out and sounds like a distorted tremolo sort of. Any ideas where to look?
Hi guys . This is my first post in this awesome forum , so be gentle on me ...
I have a couple questions :
1) Having read so many references to the Shaka OD , how come only one of the MOSFET clippers is paired with an external diode (1N34) on the OCD ?
2) has anyone tried a good old TS with MOSFET clipping?... Impressions ?
Thanks in advance .

Hi folks,
I'm not familiar with this stuff, anyway my V1.4 has 3 transistors and 3 diodes ( I think 2 x 1N4002 and 1N34A). I see marked on the PCB C12 too instead of 11 caps. Now why that schematic is different? Cuz the real thing runs up to 18V and this not? If it's not the answer why the schem is different? Just to understand.

extra transistor/caps/diode that are missing is just for the led switching for spdt... i guesss they ditch those because 3dpt was use insteadgian80 wrote:Hi folks,

I meant in the schematic. I should have been more specific.newly wrote:Yellow cap (C8 ; with a plus in the silkscreen) is Tantalum.
The blue cap are multi dip, sometime they are sold in yellow color like the tant as well.
I'll answer my own stupid question. I'm building the MarkM OVD version and C3 and C6 are ceramics. I should have known this because of how small their values are. I believe C10 is suppose to be a tantalum.
I got mine up and running. I just have a couple of trouble shooting questions if anyone is willing to help. Should be pretty easy for folks around here.
My build is based on the MarkM OVD layout
1. The tone pot is wired with lugs 2 and 3 to the board, but 1 is left off. Should I tie lug 1 to lug 2? Or do I need to ground it some where else?
2. I'm not getting full range on the drive pot. I put in a 1 meg Alpha instead of B500K like the newer version. I didn't know if that was effecting the range. Or maybe it the fact that I put a 1uF tant in at C10.
3. On the drive pot I just wired lug 1 to ground. It works, but I want to make sure that's correct.
I have a TL072 in it for now. It seems to be darker than my current OCD. I'm guessing it's a combination of that and having film caps instead of multi dip caps Fuller uses.
Thanks for the help in advance.

Are you referring to the above layout? Not getting the point?
