SD-808 Mod Plus

Pedal Type

SKU: N/A Categories: , , Tag:

With this mod I take the SD-1 and mod it to TS808 specs. The circuit of the SD-1 is very similar to the TS9. This mod includes all the mods in my regular SD-1 mod, plus you get three extra components that will take the SD-1 to TS808 specs. I have also included a RC4558P chip. The stock SD-1 comes with the JRC4558DD op-amp chip. Some feel the RC4558P is a better sounding chip than the JRC4558DD in the SD-1 circuit. I also include a 3mm Super Bright Blue LED and a resistor replacement that will increase the brightness of the LED. What’s really amazing is how great this pedal sounds with this Mod.

I also include the symmetrical clipping mod for those that prefer Ibanez TS808 clipping over Boss asymmetrical clipping. This mod is absolutely the best SD-1 mod sold anywhere by anyone at any price! The complexity of the tone after the mod is startling. We also mod the clipping section to symmetrical clipping like Ibanez uses in the TS9. You can also change the character of the pedal buy swapping out different chips which I now sell above. Compared to my regular SD-1 mod this mod will take the SD-1 and add presence and much more complexity of tone. It’s like taking a blanket off the speaker in your amp. The tone is very open, airy and transparent. Very smooth, yet biting gain. Controlled feedback and sustain is incredible with this mod. This is the ultimate SD-1 mod!

IMPORTANT — Boss has started using surface-mount components on some of their new pedals. I’ve created a page to help you determine if your pedal is moddable. Read about it here.

SD-808.mp3 — SD-808 Sound Sample – This mp3 was recorded on a Strat with a DiMarzio PAF Pro at the bridge and two DiMarzio Virtual Vintage pups at the neck and middle positions. The amp was a 1975 Fender Super Reverb and the mic was a SM57. Some parts of the mp3 were recorded with the bridge pickup coil split.

Sean_Borton_1.mp3 — Sean Borton mp3s – These mp3s were graciously supplied by Sean Borton. The clips are from Sean’s latest album “What a Party”. Sean is playing a Strat w/EMG SA (Vintage) pups through a Vox AC30 set to a clean setting. Thank you Sean for letting me use these clips. Man, what great tone Sean, Awesome!

Special thanx to Juan Pablo Tomas for making this Youtube video.

VINTAGE V2 reissue Telecaster on the computer as a clean signal (no amps used) and then I passed the track through the boss sd-1 before and after the mod. So as I used no amp the sound is quite raw but the differences are quite obvious.

Awesome! Thank you Pablu!
