if you are looking for a project out of this, i am in the process of making a schem and layout (i found a schem online for the DB-01 which seems correct close to the one i have) I'll post them in a different for people to use, The project has a volume boost, switchable inductors (red and Yellow Fass...

yea i emailed him, but he requires a gerber file... which i dont have... this is the file i have (in PDF) if theres anyone who woud like to quote me for 2 of each board with shipping to toronto, please let me know, file is attached (its the pre amp for the x88 from sloclone). the first 2 pages would...

Yea creatron seems like the only place o could think off since I go in there once a month :p

Hello, Anyone can help me make a good board? i have the transfer PDF's, just need someone to etch for me a board or two in thick track (to be used in pre-amp) Anyone can do this? please quote me price too for 2 boards of different design (2 of each, total 4 boards, 2 designs) Specs: pre board=12.125...

Would someone be able to draw out the isolated schem for one of the relay switches? i have seen the schematics for their use in channel switching (ala silver jubilee) but want to ubild a similar switcher myself.. would it be possible to get the schem for power buffering and individual relay control?...

I'd go for 2 or 3 or madbean's design as i believe they just fit into a 1950B with space for a switch... Madbean are those the dual layer design?

i'd be in for a board to fit a 1590B... even if it is double sided

yes, i suspected something was up with my series connections, i did look over other pedal schematics, seems like the others include an extra IC buffer and some filters pre and post EQ section, will update the schem and try and make a nice layout for it...

Hello again FSB! I had some time and decided to look over one of the articles TI puts out in the audio section... check it out here it is a nice article illustrating a schematic of a 10 band eq, i went ahead and drew it up in eagle, file is attached, can you please look over it and the article and l...

This is a silly question, but as i have notice, the ZV pedals "Box of...." are cascaded SHO's, so Theoretically, if i take the BOR or the BOM circuit can i just remove the tone and boost/gate circuit to get a simple distortion box? (i dont really care for any tone feature)... would that be...

Hello there FSB! I am not advanced in any way in pedal design, but the ideas are flowing, but i lack all the full out theoretical knowledge aside from ohms law and practical equations like that, but i recently was thinking as looking at my pedal board; there i have my mxr 10-band eq sitting in the s...

Would it work if i change the drill on the switch pad to a diameter equal to the lug size (0.078) and then make the actual pad size square around 0.1 inches? would that work if i get boards made or etch them by hand?

Hello there, just got eagle few days ago and started playing around, i want to try and print some board off for my self and if they go well maybe order small multiples of single boards, so i was wondering, i got the markov libraries, and am using a pcb mounted 3pdt switch, but it shows me the drill ...

Ok i've gone over the pedal and Thanks to Dirk_Hendrik's AD-9 schematic found Here and these are the changes in comparison to the Maxon: R5-1K R6-10k R9-10k R17-20k (trim) R44-10k R47-10k R50-1k R59-10k C2-470p C5-18n C8-12n C10-100n C11-270p C12-1/50 NP u/V C15-27n C19-820p C20-470p C21-1/50 u/V C3...

Update: Germanium Transistors are Russian GT308B and GT313A They we're tested for gain only, not leakage theres 100 in total 15 have gain less than 30 about 60 have gain of 30-40 10 have gain around 40 10 are between 40-50 5 about 60-80 2 greater than 80 ... Can do $30 USD... since i'm not planning ...

Ok i finally got my lazy ass around to start reversing the build so far so good, Dirk's schem is pretty much Spot on! (the maxon seems the be version 2 with the components in brackets - although there is one change for now...) but im posting because i got to the fet switching section and in Dirk's s...

I have a lot of 1/4 carbon resistors just over 600 (view attached Excel sheet) And a lot of Russian Stock germanium transistors (tested, not for leakage though) from '74 and '82 i belive Will post the tested gains (most seem to have been around 40, there are then 50,60, and few 70-90) *note did not ...

I'm not sure if such a thread already exists, but i just wanted to share some ideas, pose concearns and see if there is something optimal in all. So let me being by saying, i have made several stompboxes - with pre-made layouts (ei-Tonepad) to self-designed (not advanced) layouts. Now in my layouts ...

Just for the record, I used a red LED/LDR combination with a heat shrink tube. :D Oh not to worry, i have 3 of those on my desk (as used for protos) i think the specs were 4k light ~ 700k dark and i used the trim pots to set the sweep just right.. but thats not all! since i was way lazier than you,...

haha, cool, just got to watch the vids with sound, the wah sounds good, was just wondering in general do you think ur foot would get more tired using the RF controller than a mechanical? I'm just wonding because the idea is that u get ur foot to rest with all the mechanical parts, but with nothing t...
