Re: Death by Audio Evil Filter Better 2014 NEW (UNRELEASED) [traced]

So, I took a screen shot of their computer schematic which seems to have a few extra things going on so I'll try copying it up in the next day or two. Okay, so, based on the other schematic I found out what the fuzz/filter switches were and how they're connected to each other. So, the DPDT switch i...

Re: BAJA Orange OTR120 Graphic MkII amplifier pedal 9v 160318 [documentation]

im sorry for not getting back until now.... i was a bit sick and also had no time to move on with the project... now waiting to the odd resistor values to arrive ( like 2k7,1k2, 3k9, as i dont have them around and also i cant get close to the values combining values from what i have around )that i c...

Re: Dunwich - Wizard Fuzz [traced]

I suppose that the bottom layer of the pcb is to ground.... Do you maybe know what's connected to the top layer ? Thanks

Thanks a lot Bajaman for the reply and enlightenment, im sure i was a bit confused by the Vero layout... Exited to build this one, as im a little tired of those "amp in a box" using FETs and biasing thing and inconsistency of the circuits somehow... Thanks for this great OpAmp variation......

Re: BAJA Orange OTR120 Graphic MkII amplifier pedal 9v 160318 [documentation]

Nice! im going to start soon this project, as a newbie here i dont see, on the Schematic, any 9V conection to the transistors BC547B, but in the Vero Layout i see that the 9V goes one on the Base and another on the Emitter of the BC547B....... not that im saying that something is wrong... ( most lik...

Re: EH - Low Frequency Compressor [schematic]

:troll: Hi branleur... Do tou still have the final pcb and schematic of this one ?? Cheers!! I've drawn a PCB for the EHX LFC. After some disagrement, the LFC seems to work. I use old low gain transistor (like 2n1711, 2n2905...). Hight gain transistor do not match with the LFC. I use 741 IC. I mods ...

Re: EH - Low Frequency Compressor [schematic]

Hello everyone!

i know its an old thread, but seems that all image attachments are broken,,,,, can't find the final corrected and working schematic or layout, etc... if somehow, anyone happens to have them around and wanna re-upload them ,, would be a great help !!! cheers and thanks in advance!!
