As the name implies the SD-2 Dual Overdrive has two separate OD circuits. The Lead Mode stock is pretty good actually but the Crunch Mode not so much. There’s also a Lead/Crunch Mode that allows you to switch between the two modes. The concentric pots allow you to have two separate settings for each mode. A foot switch can be used to select either mode remotely.

I have added more gain to the Crunch Mode and tightened up the EQ in the gain. Stock the gain is very compressed and flabby. I have added a 2N3440 Transistor to the Crunch Mode that adds saturation and harmonics.

On the Lead Mode I have added gain and Harmonics. I found the Lead Mode to be way too compressed. After the mod the gain takes on this really saturated harmonic gain that just sings. Not too many pedals offer two gain modes and that makes the SD-2 a very unique pedal. I also offer a cap upgrade for this pedal. These older pedals suffer from caps leaking and going bad over time. Replacing them tightens up the effect and reduces noi

Boss SD-2 Pedal Cap Upgrade Mod Kit

Electrolytic caps in tube amps, over a period of time, start to leak, loose their tolerance and go bad. It’s just the nature of Electrolytic caps. Sometimes the leaking is actually visible. But Electrolytic caps can look okay and still be faulty. By replacing Electrolytic caps in older pedals you can actually improve the overall effect of that pedal. Honestly I was skeptical until I received an email from a client that was having issues after he modded his Boss BF-2 with one of my kits. He said the flange effect was barely noticeable. A couple of weeks later I received another email from the same client. The client said he had solved the issue by replacing all the Electrolytic caps in his BF-2. This peaked my interest so I started experimenting.

I was astonished how some of my older pedals benefited from the cap upgrade! Noise seemed to be reduced and clarity and presence of the effect were enhanced. I am now offering these Cap Upgrade Kits for many of the pedals I offer kits for. In some cases some of these caps are already upgraded in the kits that I offer. But I am offering kits that replace all the Electrolytic caps for those that have not purchased my kits. They will benefit from upgrading the Electrolytic caps that I do not replace in my kits. You’ll find that some of these same caps are already replaced in the kits I offer. It’s a win win all around for those that want the maximum benefit when upgrading their pedals. But I didn’t stop there, when possible I have upgraded these Electrolytics with Metal Film and Tantalum. Not only do these caps have tighter tolerances but they will also last the life of the pedal.
