Boss / Analog Man SD-1 Super Overdrive Yellow, Near Mint, $110.00

USED / NEAR MINT CONDITION
We modify the Boss SD-1 Super Overdrive to basically Ibanez TS-808 specs, including the chip. This is the yellow Boss pedal, not the orange DS-1 Distortion. The yellow SD-1 has the same basic design as a Tube screamer but with asymmetrical clipping. We can leave the clipping as-is (Boss style asymmetrical clipping) if you wish, but we normally change it to the Ibanez (symmetrical) style on my standard SD-1/808 mod. Ibanez told me that Roland (Boss) has a patent on asymmetrical clipping, which gives it a bit more volume, harmonics, and crunch. With Ibanez style clipping, it sounds similar to a TS-808, but still has a touch more edge and drive available. With Boss style, it gets yet a bit more volume, edge, and harmonics. The Brown option is standard on the SD-1 as it really helps to smooth out the sound. We can change the LEVEL pot to a PUSH PULL POT in order to switch from stock asymmetrical clipping to Ibanez style symmetrical clipping. This is a $25 additional option at time or pedal or mod order, or $40 to later add just the push pull pot to a pedal. When PULLED OUT, you will get the louder, crunchier Boss asymmetrical clipping. Instead of the push/pull pot, we can mount a mini TOGGLE switch to select the clipping. It's the same price and may be harder to accidentally change the setting on. We put the toggle under the LEVEL knob as seen in this picture.
