What is it that you want to change? I'm waiting for the service manual from Boss for mine. I want to see how similar it is to the SD-1/OD-1 and the DS-1. I'm looking to get an SD-1 and a DS-1 for comparison purposes as well. Now that I've heard the OD-3, i'd like to mod the SD-2's Crunch channel to be more like that. The OD-3 is a completely different animal. It uses FETs to generate distortion, not op amps.
Grace and peace,
Steve

I want to have the crunch channel to sound like an OD-3. I seldom use the crunch function of the SD-2. Please keep me updated.
thanks!
one more question, how do I get the sweeping effect for the mt-2? |

GOB, I just got a (photocopy) of a SD-2 service manual, but I'm not sure what to look for re: possible mods. (my soldering technique isn't pro-level yet, and I'd need to buy some junked/broken Boss pedals to practice on before I got into pedal mods.) Steve is probably better qualified than me to answer mods questions, but let me know if I can be of help.
Steve, may I ask how you'd get such a service manual from Boss? (is it something anyone can request, or do you need to have 'connections' to obtain one?) I guess its schematic is available online at freeinfosociety, but I'd like to obtain an (original) service manual for my favorite pedal, the SD-1.
and I think GOB is referring to Analog Man's MT-2 mod, where he cleans up the noise(?) as you sweep the midrange eq knob:

Pawnshop,
Thanks for the info. I'll check it out.
I call Boss at 323-890-3700 and order the service manuals as a consumer. They still allow that in the US. In Canada they will not sell service manuals to consumers or ship parts outside of Canada. I've been buying up Boss service manuals like a fiend lately in case they come to their senses and stop selling to consumers.
I've easily spent $300 over the past several months. (Hey, I coulda bought an SG-1) They charge $5 S&H per order, so I usually buy several at a time. A few are $5.50, most are $9, and some are $15.40 each, so they ain't cheap. Some are originals, lots are copies made by Boss. BTW, Ibanez will mail you copies of what they have for free. They don't have them all, but they have alot available. The trick was finding them as Hoshino USA - they don't list themselves as Ibanez - 215-638-8670.
Being a pseudo-musician (and one of those God fearing, Jesus follower types ), I'm also kind of sensitive to copyright laws, etc. so I like to pay for the originals. I thought it would be cheaper than having to buy all these pedals, too, but that doesn't seem to be working out so far! 
Oh, and check out R.G. Keen's soldering tips page at:
http://www.geofex.com/Article_Folders/how_to_solder.htm
He does a great job giving you the technique. After you done it awhile, you don't even realize what you're doing anymore. I read through his article and kept thinking, "that's EXACTLY how I do it".
The only thing I'd add is:
Don't blow on the solder as it is cooling! Wait for it to set up on its own. And don't work with a fan blowing on you and your work, either. It does the same thing.
And speaking of not realizing how you do things, I came across a great website a few years ago about playing the guitar:
http://www.guitarprinciples.com
He accurately explains why people with natural talent or gifting are not always the best instructors, because they don't necessarily know why or how they do things, they just do them. Jamie's right on as far as proper guitar technique IMHO. I learned alot from him and his methods. I had to correct a lot of old habits, but it's made a definite difference.
Now, being a born again Jesus freak, I can't endorse his constant references to his personal spiritual philosophies, but I think his guitar stuff is very helpful. "Eat the meat, spit out the bones", as they say. 
Hey, I gotta get some work done today! 
Grace and peace,
Steve

GOB, I'll see what I can do to help, but it might be a few more days. right now I've got a sh!tload of exams to grade  , which have dominated my time lately. and since the pages are larger than my scanner, it's not a trivial task....
and thanks for the scoop on soldering and obtaining official Boss service manuals, Steve!  I can rewire a guitar with no problems (except for the occasional fried capacitor), but since ICs are much less forgiving, I just need to practice my technique. and I'll definitely give Boss a buzz after the Christmas holidays (I guess they accept credit cards over the phone?).... |

Yes, they accept CC over the phone.
2 other soldering tips after my lastest butchered pedal has arrived.
I see a lot of cold solder joints and lifted traces and I'm guessing they are because of 2 things:
Don't use a small pencil soldering iron. You need enough heat to get in & out fast or you'll lift the traces and destroy components. The best thing is a soldering station with variable temperature. They are expensive, but they last for years & years. You need more heat to solder & de-solder connections on jacks and places with a large surface area of metal than you do PCB work.
I see that alot of DIY mod kits come with solder wick (solder braid). Get a solder sucker like the Soldapullt (like catapult?). Search on ebay for solder sucker, you'll find them. Get the big blue one. I've never liked working with solder wick to remove solder and it makes you keep the heat on way too long for most things. It's good to have to clean up small amounts of solder that you can't suck up, but the soldapullt works a WHOLE lot faster and better. The trick is to add MORE solder to the joint first, then suck it all up after you let that addition cool. You will have to clean the solder sucker from time to time to keep the suction strong. Use a silicone spray or liquid lube that won't damage the rubber o-ring. I'm sure you have some around for your foosball table, right?
Grace and peace,
Steve
