DEFX makes some really great clones/remakes of old, expensive and hard to obtain pedals.
The mail carrier just came by and dropped off the DPDT momentary foot switch I needed to finish this one off...
The Echodrive Red is a PT2395 delay that is digital but sounds kind of analog. It has a 12AX7 configured as  pre and post gain stages... The nice thing about this tube based pedal is that it doesn't use wimpy non tube voltages like 12, 24 or 30 volts... It drives the tube with around 190 volts on the tube! All this in a pedal!
20-30 repeats is easy for this pedal and there is a "slam" switch that not only makes the pedal go into oscillation, it also modulates the delay time for a really great sounding effect.
This build was involved but the documentation is great and everything well explained.
I did a couple of deviations from the instructions... First, this pedal has two regulators... A 5 volt and a 12 volt. The 5 volt regulator input feeds off the output of the 12 volt regulator which I don't really care for... In the past I've had instability problems when feeding one regulator off the output of another. Basically, I butchered a trace that fed the input of the 5 volt regulator and ran a wire to it from the raw DC supply. I also dont like big value caps (1000uf) on the outputs of regulators, it's a recipe for blowing a regulator... So I changed a few things around on the power supply.
This uses a 12vac power supply input and rectifies it for the low voltage section of the pedal and this pedal also uses a small torroidal transformer in reverse to get the high voltage needed for the tube. Ingenious design!
I'd like to thank Dino for making this available. This was an expensive project but much more do-able than buying an original, which goes for crazy money.

This thing is next level. I'll have to check out its tones.

I took it to a friend's house today for him to run it through its paces. This thing can do some neat-o sounds! The tube drive is nice also as it adds grit/dirt to the "wet" signal. Sounds close to a tape echo, very nice indeed...

Neat. I built one of their Select-A-Fuzz boards. It sounded great and was really high quality, My only complaint is they don't leave room for jacks and switches and use up all the space in a case forcing you to do weird things. If they would spend a bit more time on the boards I would buy pretty much everything they put out.
That which burns twice as bright, burns half as long.

Looks great! Nice work. I am excited to get to this one when the queue abides😎

Oh man, cool project.  Gonna read up on this, nice build too!  :)
