Modded Faux Analog Echo

I did my own layout for the Faux Analog echo using the schematic by Intripped on freestompboxes.org

But I modified it to use an analog fet switch and wired it to have two modes, true bypass or buffered bypass with tails. I also included a temporary DPDT footswitch and a SPDT that you can use to have a temporary ON or temporary OFF effect when the pedal is on, either in true bypass or buffered bypass modes. Watch the videos below to see how it works and all the posibilities it offers.

BJFE Blueberry Bass Overdrive

One day last month a user called JFace show up out of the blue at FreeStompBoxes with a trace of his original BJFE BBOD, one of the most searched OD for bass, it was like the holy grail, a lot of people searching for it as it was supposed to give the eternal tone. I now understand why, this thing sound freaking awesome.

This is my veroboard layout, verified and boxed:

This is how it looks

Analog FET Switch, daughter board for Deep Blue Delay with Tails mod

I'm aware that my Deep Blue Delay with TAILS mod is being used as it is one of the most visited post on this blog, and the DBD is quite popular in the DIY community, but I'm not happy with my mod. After using it I realized that it doesn't always open completly, so the delay line continues engaged. In this post I present what I think it's a better alternative, although I haven't tested it so this is NOT VERIFIED,

I took the mod idea from the Small Time Delay and used the same implementation, but the mod is just an Analog Fet Switch, used in a lot of pedals in the "non true bypass" era. In the next article you can see how it was used by DOD.

It uses a flip flop and two fet switches. You can simulate the switches easily in LTSpice with the next schematic, but we only need one.

You can read more about FET switches at this thread on DIYSB, I have read a lot but I don't feel qualified to try to explain it. I just realized that it should work better with the DRAIN and SOURCE of the FET biased properly rather than relying on the previous and next circuit sections to do it.

I haven't tested it so this is NOT VERIFIED, but this should work better as a daugther board for the DBD Tails mod. The green wire should connect to A in my modified layout, and the blue wire to B. For the indicator LED take the V+ from the control wire.

This is the DBD modified layout (the same I posted on 12/2013)

If anyone try this, let me know to tag it as verified.
