Hi guys,

Having a bit of trouble with my Sharkfin pcb and I want to eliminate the possibility that I am simply testing it wrong using my rig.

There are a number of outputs at the bottom of the pub. Which should I be connecting to the rig to accurately see if it works?

Thanks,
Mark

Hi everyone,

I built my total recall a few months ago and I had some issues following the biasing/calibration section of the build doc as others have mentioned. I ended up calibrating it by ear and have been really happy with the pedal.

I had never played a DMM before, but I knew that I was about 90% there with my build, but not 100%... So, today I rented an actual DMM for a day or so to compare as I calibrate my TR (Hence the URGENCY... I want to get it all done when I am off tomorrow!)

Anyways...

Do I NEED to take out all of the MN3008s before recalibrating, or can I just leave them in their place?

The reason I ask is that I have had chips lose their legs when I removed them in the past and this is a major pain. I would hate to ruin a MN3008 and I would much rather be able to leave them be.

BTW... After comparing the real DMM and the TR, I am convinced that I can get the TR extremely close with a bit of tweaking. They already sound extremely close, but my TR is clearly not calibrated 100% correctly.

Thanks for the help!

On the Mangler PCB, can I use a 1N5819 in place of the 1N5817?

Thanks

I was wondering if anyone would be able to give me a hand. I am trying to use to the Mangler PCB to build a Mk1.5 Tone Bender. I understand they are, for the most part, the same aside from some values.

I have been using the following schematics to work through this. I have been able to identify most of the changes that need to take place, but a few things on the Mangler PCB confuse me. These are mainly:

R3 - 220R (on mangler schematic) - can't find this on the mk1.5 schematic and I am wondering its purpose/effect on tone

C4 - 10pf (also on mangler schematic) - also not on the mk1.5 schematic...

I think I have sorted the rest out, and obviously there is more going on with the built in road rage power system as well.

I have included the images. Thanks for any help.

Mk1.5
