"turboultrasupermegacrunchomaticchoraldrive 2000000000" Wow you have that pedal to? What a small world.

Re: what the diff between the boss overdrive and superoverdrive?
OD-1 old original with volume and gain. Had JRC 5881 chip. the best sounding one.
These are sought after by pedal collectors now.
SD-1 added a tone knob, changed the chip. Lesser tone than the OD-1.
Turbo OD added some knobs and bells and whistles. More versatile...not necessarily better

Re: what the diff between the boss overdrive and superoverdrive?
There's some circuitry difference between the OD-1 and SD-1 aside from the tone control as well.
In the SD-1, the signal goes in to the non-inverting input (pin 3) from the first stage of the opamp to the second. In the OD-1, the signal goes in to the inverting input (pin 2) from the first stage of the opamp to the second. Yes, there is a sound difference when doing it this way.
The tone control of the SD-1 is in the feedback loop of the second half of the opamp just like the diodes are in the feedback loop in the first half. With no tone control in the OD-1, there's just a simple roll off filter there with a resistor and capacitor in parallel, like the SD-1, just minus the tone pot.
The input section has a couple part value differences between the two and in the output section, the SD-1 has one additional resistor. The clipping section is the same in both. A SD-1 can be converted to OD-1 specs fairly easily.
I haven't looked at the Turbo OD schematics to really know what Boss did in that one.
There were several different versions of the OD-1 through it's life, mostly changes in the opamp (5881 not being on, that's a tube....lol). The 4558 opamp from various manufacturers was most common but before those there were a couple others used, RC3403ADB and uPC4741C.
I'd love to get a hold of an old OD-1 myself but considering the prices are stupid high for those things now, I'll save my money, get another SD-1 and change it to OD-1 specs.

I'd like to see Boss fit THAT on the face of one of their pedals.

Re: what the diff between the boss overdrive and superoverdrive?
i've been trying to find some cheaper OD1's for ages but they are always expensive....
i do use an SD1 a bit.... i paid $30 for it used... it does a lot for $30.... i guess people lose sight of the fact it is a cost effective pedal.... there is always better more expensive pedals out there... but it is build Boss tough... i still prefer DS1's over SD1's... but i do use the Boss overdrives as well

Re: what the diff between the boss overdrive and superoverdrive?
When I was in my late teens, I used a Boss OD-1 into a Jubilee 2555 100W head and everyone who heard it thought it was the best highgain Marshall tone they'd ever heard.
The only thing I didn't like about the OD-1 is it didn't have a tone control, so I put an ad in the paper to trade it for an SD-1. As soon as I'd swapped pedals with someone, I realized I'd made a mistake. He probably laughed all the way home! Doh! Back then, I had no idea about the circuit or chip.

Re: what the diff between the boss overdrive and superoverdrive?
from what ive seen, about $100. Depends if you get it done by someone or yourself though.

Re: what the diff between the boss overdrive and superoverdrive?
Yeah, but more fun....used, $30 from eBay. Turbo Off mode sounds like a slighly weaker SD-1, but Turbo On gets you a lot of drive. It's a little mushy, and just a little harsh, but loads of sustain and singing solos. I'm also looking into the SD-2, but I have never liked the SD-1.

Exactly. For the non-DIY person, it may be worth spending the extra for the original green finish and look and all that. But for the DIYers, save the dough and make the few changes necessary. In my scenario of changing the SD-1 to OD-1 specs, I'll save several hundred dollars.

Re: what the diff between the boss overdrive and superoverdrive?
I have an old OD-1. On ebay, the competition really isnt that fierce for the metal csrew, non origianl production ones. I saw one go for less than a hundred. I will give a link to that auctio later. But , Ive never seen anyone doing those SD-1 to Od-1 conversions. Where did you find that??If so I would sell my Od-1 and get a cheaper sd-1 modded to Od-1 specs.The only mod ive sen is analogman will convert a later Od-1 like I have, to original Od-1 specs for 70.00.

Re: what the diff between the boss overdrive and superoverdrive?
I got the mod a few years ago of the diystompboxes.com forum. The circuit path is identical other than inverting vs. non-inverting input at the second half of the opamp. Change that, a couple other part values here and there, disconnect the tone control, bingo, it's an OD-1. The opamp doesn't need to be changed either since the 4558 was used in later OD-1's as well. Good luck finding a chip that was used in the very early ones as they're mostly not made anymore. IMO, that's all mojo. The 4558 does the job just fine.
I have the service manual schematics from Boss for both so it's not hard to compare the two and figure out the differences. I haven't seen anyone do the mod either but it can be done.

The OD-3 is a much different circuit. The clipping is different, there's more transistor circuitry before the opamp, the tone control implementation is different. There's quite a bit more going in that one.
