DS-1 moddity

[Gr8Scott]

I have an issue with a modded DS-1 that I've been soldering on. It's a decent enough sounding pedal on it's own, so I bought it with the intent to mod it. I added a few film caps in place of the original polar caps and added one extra germanium diode to the back of the board because I couldn't fit it up top. I initially found that the pedal made an unflattering sounding blat when the gain is cranked to 3/4 of the way up plus the gain is now very low on the pedal. I corrected the initial problem with one of the cap legs contacting the resistor legs and causing a connection. That is now no longer a possibility as the legs are both covered in shrink tubing.

The ugly blat noise is still there at 3/4 gain with single coils and sooner with humbuckers. Should I remove the extra diode?

You should send it to me and let me mod it correctly for you!

Re: DS-1 moddity

The extra germ. diode would mean that it would swing an extra .3v on one side of it's clipping cycle, (either pos. or neg.) so if it's .7 on one it would be 1v on the other. I don't know if it has to do with the problem, but I hope it helps.

He needs a pro to get him all fixed up,as the circuit board is probably overheated..

No offense intended, but how in the world are you guessing the PCB is overheated without even seeing or hearing it?

Scott, pull the diode and see if it goes away. FWIW, when you're trying out new new mod ideas, do them one at a time, so if something like this happens, you'll know exactly where the problem is.

Re: DS-1 moddity

John's probably right. He does the best mods I've ever heard and he's modded a few of my pedals.

He has alot of experience with this stuff and has already gone through the learning process and can recognize the common mistakes inexperienced pedal tweakers make...such as overheating the board.

I would agree that he likely knows many of the mistakes new guys are gonna make, but it makes a lot more sense that the noise is being caused by that extra diode than an overheated PCB.

If you meant he's right in that Scott should just send the pedal off to be fixed, then I wholeheartedly disagree

Re: DS-1 moddity

If the diode is wired in parallel with the other clipping diodes, it would be my guess that it is the culprit.

Cause he told me via PM that he had to bridge across traces along the board...You only bridge across when you burn open and across the traces.....LOL

Geez.......Have your buddy send me the DS1 and I'll fix it for free! No big deal....Instead of getting in the middle of something,or you fix it for your buddy!

Amen to that and I have! Screwed up quite a few pedals when I started doing this stuff!

Send me your pedal and I'll fix it for you....Merry Christmas! PM me for the mailing address....

Send it whenever you like Scott and I'll get it taken care of...
