Description Technical Specs
Analog Man modifies the Boss DS-1 distortion into our DS1/Pro specs, with optional MIDRANGE knob to make an awesome sounding distortion pedal.
Mike Hermans demonstrates the DS-1/Pro and our MT2 and GE7 mods.
No longer available new, sorry! If you can find one you can send it in to us to modify.

We are trying to keep a few used orange ones in in stock in excellent condition, often with the original box. Any options are available on these.

We have a mint black anniversary one in the box for an extra charge, email if interested.

April 2020 - We got a few more new ones but had to raise the price, sorry!

June 2017 - The orange DS1 is now using a tiny circuit board and SMT parts, which we cannot modify. These types of mass produced pedals are cheaper to build but usually impossible to modify or even repair. We don't have any of the original handmade orange ones left but we can still mod yours if you send it in.

October 2019 - We had the black 40th anniversary models in stock, which were still handmade, but are now sold out. These were discontinued in 2018 but we sold them until late 2019.

Boss DS-1 Distortion mods

DS-1/Super - our older mod

The DS-1/Super mod takes the oldest 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 Japanese or 1st version Taiwan DS-1 that has the old style chip that we can't change.

DS-1/Pro - our current mod on new pedals

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 distorting. 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 Made in Taiwan 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 what we recommend. We cannot mod the 2017 and newer pedals which have the power jack on the edge as on the right pedal and are usually made in Malaysia.

DS1/Pro Midrange Mod

The DS-1 has quite a scooped midrange, especially stock. This is cool for heavier modern sounds but sometimes too thin in the mids for classic distortion sounds, especially through a Fender type amp. After our PRO mod, the lows are better but but it's still quite scooped in the mids. In 2007 we came up with a mod to allow dialing in more mids for more of a classic tube amp sound. We can now add a small MIDRANGE knob under the TONE knob, as a $25 option. It has the exact stock midrange setting and sound at about 10:00. Turning it up gives more midrange and a little more volume. It works along with the TONE control. We can sell you a new DS1/Pro with this option or mod your DS1 pedal.

There is no room on the old style DS1 for the midrange pot on top, as they use large pots. But we can add the midrange pot sticking out the back on the side of the power jack, or out of the right side along the input jack. Let us know where you want the knob if you send in an old style DS1.

For best sound on the DS1, keep the TONE knob very low. Our midrange knob works great then, allowing you to add in the normal frequencies that sound great with guitar while keeping the annoying high end under control. Another cool setting this mod allows is to run the TONE knob up really high, which is usually terrible. But by turning the MID knob up really high, it smooths out the sound and gives a cool tone, very loud too if needed.

Here is a DS1/Pro/Midrange review which ran in Premier Guitar Magazine in October, 2008.

5 of 5 Fantastic Distortion Pedal! April 14, 2022
Reviewer: John DiLoreto from Glastonbury, CT United States  
What a difference the mod makes. It takes the DS-1 to a very amp-like distortion, and the mids knob helps to really cut through a mix and give it a very thick sound and feel

5 of 5 Super Thud September 9, 2021
Reviewer: Brett Huhn from Columbia, MD United States  
Great usable sound on the whole range of the distortion knob. The Mids knob on the outside is super handy. I can keep the sharp tone this around 9 or 10 o clock,as SD-1 get sharp ;), and use the mids knob as a tone enhancer because that is the size of it.  I guess I could mids out for a Stratocaster, but I don’t know, I’m not a complicated guy. I used it with a few pedals bashing into it and then I tried it the other way bashing it into a Prince of Tone  and I really like that, with the Dist dialed in at a whopping 10pm. My guitars volume used to set the gain of a dimed Supro BK12 works well with this setup. So …. DO IT!!! Yeah Dats Right …. Also this thing has the nostalgia without the disappointment……

5 of 5 A beautiful rich tone April 14, 2021
Reviewer: Robert Espinoza from Los Angeles  
The distortion has a rich, slight swirling of the wet and dry signals. It's very slight but thick. I love it.

5 of 5 Awesome organic distortion January 28, 2021
Reviewer: olivier cambier from nogent sur marne, Ile de France France  
I recently got this pedal out of curiosity. It's much better than I thought it would be.
There is something that bugs me with distortion pedals: often, on long release chords, you can hear some separation between the distorded sound, and the clean sound. Almost like some bitcrush effect that disapear at some point while you can still hear the remaining sustaining clean sound slowly disapearing, making those pedals sound "fake". That's surely not the case with this DS1: on long sustain chords, the sound remains distorted even when it fades. It feels organic, tube-like. It's not some fake distorted layer added to a clean layer of sound. It's a beautiful organic distorted sound. I love it. Awesome overdrive with the drive all the way down, still more gainy than a POT/Tubescreamer at this level of drive. It becomes a great Marshall-type distortion when you crank the gain, with lots of beautiful harmonics when used with humbuckers. So awesome, thanks Mike !

5 of 5 Boss DS-1 Pro October 1, 2017
Reviewer: John Noonan from Epping, victoria Australia  
For many years I have suffered from G.A.S, changing pedals, trying a multitude of distortion/OD pedals. I recently received my AnalogMan DS1 Pro and after only two weeks I have finally found my tone and sound heaven. Whether stand alone or stacked the modded DS1 is one of the best pedals I have ever used. Like many players, a Boss DS-1 was the first distortion I bought. If only Mike was modding gear back then!!!
A very big thank you to all at AnalogMan
