Allédyne is the banner name I put on anything software or hardware I create or modify. In the beginning, I started throwing this name on modified software synth GUI's and DAW GUI's. As I began developing hardware mods and adaptions, such as electronic drum trigger systems, partscaster guitars, guitar pedal mods, and audio circuit desgns, I adapted this name to those projects as well. . .

Since 1981, the Boss SD-1 has been found on the pedal boards and recording studio floors of a myriad of performing and recording artists. As Roland Corporation's answer to the Ibanez TS-9 "Tube Screamer", this pedal has become a classic in it's own right. I first off have to give kudos to the person or persons at Roland who originally designed this pedal; even if they may have referenced the circuit design of the TS-9 heavily for the SD-1 topography. Honestly, many, many pedal companies and boutique builders have copied the original TS-9 design. Never-the-less, I, of course, did not design this pedal. While It's been a cool challenge to come up with and install circuit modifications to the original design that enhance the pedal's capability for differing music genres, it is a different thing all together to design a workable electric circuit from the ground up. If it weren't for the engineers at Roland and other companies, I would not have a pedal to create modifications for.
The objective of the Allédyne modification of the Boss SD-1 Super OverDrive is to provide the recording guitarist / musician with a single, affordable, hot-rodded, yet versatile overdrive pedal to set up a tailored guitar sound for backing / rhythm guitar performance and bed tracking. While this pedal mod can certainly be used for soloing and stacking with other pedals, it is clearly designed to remain within the overdrive range. That being said however, turning the knobs up all the way will, without question, rock the house. . . It gets seriously meaty.
Circuit modded features include:
Aesthetically modded features include:
The Allédyne modded SD-1 exhibits a wide ranging capability for crafting
all sorts of tube like “break-up” sounds, from punchy bell like Vox / Fender to warm burning Marshall Plexi. . .
The tone control has been re-voiced to allow the response of the pedal to remain
musical even with the knob opened all the way. No more fizzy, thin, or shrill top end.
Two clipping modes work with the Level and Drive settings for honing in on that “just right” sound.
More available gain with an extended low frequency response helps the pedal push a tube amp’s clean channel into an overdriven state by using the Level knob alone (boost configuration).
