"Boss DS-1 Distortion mods
DS-1/Super
The DS-1/Super mod takes the orange DS-1 distortion pedal, and gives it a professional makeover. The DS-1 can get a lot more distortion than a tube screamer type pedal (like the Yellow Boss SD-1) and make a Fender amp sound like a Marshall after our mods- very full, deep, and rich. The stock Boss DS-1 is fairly thin and buzzy sounding, with a loss in low end. After our mod, the pedal will be a bit louder with all knobs at 12:00, and a much thicker, fuller sound, with no high end tinny buzzing. Just a true distortion sound, a lot less like the sound you get out of a pedal.
Our DS-1/Super mod was designed by Ohbayashi San (CAMTAC) and fine-tuned by Analog Mike. It replaces many of the cheap components that Boss uses (in order to make the stock pedal a super deal for the price) with expensive, high grade audio parts. It does not use LEDs in place of the diodes, but a special NOS diode as used in our SILVER mods. We also re-equalized the pedal for a punchier sound without adding more distortion or noise. Our mod actually removes a ton of high frequency noise from the pedal! This mod has been outdone by the PRO mod below, so it's only done now if you have an older DS-1 that has the old style chip that we can't change.
DS-1/Pro
The DS-1/Pro mod is the same changes as the Super mod but it pulls out the stock inline chip, and replaces it with a JRC op-amp chip. This chip really improves the tone, giving it more warmth, clarity, and headroom. It's still a DS-1: more distortion, crunchier, and more low end than a tube screamer, and after the mod it sounds awesome even with the DIST knob down all the way. It is a very useful pedal with the DIST knob down for people who don't want too much distortion, or have an amp that is already distortiing. It does not have the midrange hump of a tube screamer, it actually has a scooped midrange for more of a modern sound. Most people will use them at high DIST settings, but they sound awesome at low DIST settings too. Play gently and get a clear, clean tone, play harder and the crunch and distortion comes out clear and full!
The PRO mod is only available on new style DS-1 pedals which have the power jack attached to the circuit board like the pedal on the left. The chips we use will not fit in the older Japanese or 1st issue Taiwan DS-1 pedals (on the right in the picture). The older version's chips are good sounding anyway, so they sound great with just our SUPER mod. If you have a newer DS-1, or are buying a new one from us, the PRO mod is your best choice for tone. "
Elle concurrence les MIJ (bien meilleures que les MIT selon les puristes) avec un meilleure qualité des composants.
