Hey guys, first i'm really really sorry for not returning any emails. I've been busy these days ya know and also my computer got repaired. I really apologize to all of you. But don't worry just wait for those requested layouts. Thank you

Fuzz Factory

Well, this is not new as there have been so many FF projects lying around the net. And I just decided to do a layout since it's so very easy. Pots are mounted directly to the PCB and should be placed vertically like those in original zvex's. I used 125B type box with no problems. Please note that transistor values are my own choices. Components below the "STAB" pot(ie 4.7K, 390 ohms, and 22uF cap) is an LED anti-pop circuit.

Sansamp GT-2 and BDDI 3-band EQ

I heard a lot of issues regarding the active EQ's of the Sansamp GT2 or Bass Driver DI as it it too hifi sounding. Well, for me it doesn't really bothers me at all because I always like these pedals. What I have here is a 3 band active EQ taken from the other Sansamp - the Tri-AC. I didn't mean to replace the existing stock EQ of the original circuit but rather using both one at a time will be a good idea. By using a DPDT or 3PDT toggle switch, meaning only one EQ circuit will be used while bypassing the other, not bad huh?. Please watch out for the connections. The pad labeled "V/2" refers to Vref(4.5V) and should be connected in the main GT-2 board where Vref is located. You should know it's location, say, if Tonepad's board is used(ORANGE colored pcb tracks). There's plenty of room to drill on that board. IC is a matter of taste so try whatever suits you best and always use a socket.

Box of Metal with GATE control

This is again the Box of Metal from zVex's but with a GATE control. This is not the actual gate circuit of the original. The gate control is taken from G2D's Morpheus pedal. I haven't tried it yet as this was meant for experimenting. All the non-labeled transistors are BS170. Opamp can be any as long as it is a single one. Feel free to comment.

Fulltone OCD v4

The layout to be presented this time is the version 4 of Fulltone's OCD. Schematics are everywhere including the other version. The MOSFET is a 2N7000 and the LED anti-pop circuit is also included-the one labeled "LED" is where your indicator LED must be connected. The layout is verified. This pedal sounds so good on it's own.

Parametric EQ

What I have here today is a parametric EQ from a japanese schematic. I haven't built it but the layout is correct as per schem. This looks simple and interesting so I decided to make a layout on this one. I already did the Ibanez PQL but i'm not quite satisfied with the results. Well, maybe this one is not bad at all as it is in my "to-do" list now. I would suggest to use reverse audio pots for the Q and Frequency pots(dual gang). Be careful with the jumpers especially at the TL074 opamp. It would be nice to solder an insulated wire at the copperside. Sorry, I just want every layout to be compact as possible. The numbers labeled as "3 2 1" is pretty much standard in pot designation, ie 3=CW, 2=W, 1=CCW.

MXR Zakk Wylde OD(ZW-44)

This is the MXR ZW-44 overdrive layout taken from Analogguru's schematic. I did not include Jack Orman's anti-LED pop this time but i use the original's LED switching instead. The pads labeled SWITCH is going to be connected in the 3PDT footswitch(if this will be used instead of DPDT). Please take note that the square pads of the diodes is the "+"(banded side or the cathode). Layout is verified.
