EQ and more Distortions!

Yamaha NE-1 and some customized distortion circuits to be posted this week. More over on this next time!

Tech 21 XXL

Here you go as requested, this is the Tech 21 XXL distortion layout minus the CMOS switching and the input buffer of the original circuit. You may want to add a capacitor from 0.1uF-1uF in the jumper labeled as "Cin?" and also changing the biasing ressistor labeled "100K??" into a 1M resistor. Anyway, that is just only a suggestion. Pots are all 100K LINEAR.

DNA Gain F***er 2

This is the layout of the Gain F***er 2 distortion from DNA Analogic. Pads are provided to FETs and bipolar transistors that has different pinouts. Pots are all 100K. I would recommend using log tapers at DRIVE and LEVEL controls, a reverse audio taper at CUT, and a linear one at the FXXX control. Enjoy!

Hi, mi amigos!!. Starting today layouts will now be provided with download links as you can see. Every now and then links are added accordingly. Thanks. c'ya.

Enjoy!!!

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.
