Dirtbag Delay
« on: August 17, 2011, 05:37:58 AM »
Teaser build  ;)

Prototype board complements of Brian!  This build is a beast.  Fired up on the first try and I really took my time checking every resistor and cap on this build.  Enclosure is a 125-BB with an etched aluminum plate.  It sounds awesome and the modulation can get real crazy!  Genuine mn3005's in their finest circuit.  It's a buffered bypass but it sounds great at the end of my chain.  Thanks again Brian!

Here it is!  Enjoy  :) Josh

Wow, great job!  I can't wait.

Are those 2 .5W or 1W resistors?
Does it use short pin pc mount pots?

thanks

I used these.  Steve didn't have all the values I needed in the smooth shaft so I went with the knurled.

The two large resistors are 1W.  When sourcing I'd look for the smallest 1W resistors you can find.  Mine were a little to big but I made them work.

It's official. I'm going to have to make a larger effort to find a pair of MN3005 chips.

Damn that looks good. Nice and tight in there. Do you think it is possible to fit in a 1590BB? Or should we plan on something deeper to get those jacks to fit like a 1590C or a 125BB? Is that the PPP custom aquamarine finish? Looks very good.

I'd go for the 125-BB or 1590C.  I had to file the some of the fiberboard off my jacks for clearance.  I used a 125-BB  I could have made them fit like Brians but I opted to put the pedal vertical for pedalboard space.  Either way it is REAL TIGHT and insulation was required to prevent shorts  Planning the enclosure drill was time consuming and challenging.  The revised version will have a little bit more room for clearance.  If I build another I'm sticking it in a 1790 so I can add a feedback switch and any other mods like expression jack etc...

The enclosure is aqua illusion.  It sparkles in photos but in real life it looks very dark.

The revised version (not the one shown) will make an easier time of a 1590BB. I don't think it's going to present too much of a problem.

This look so PRO.
I would not mind some audio samples :)
