www.analogman.com 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.
The MT2/pro mod takes the fakeness away, that cocked-wah super-saturated, big hair, harsh and noisy distortion. It leaves plenty of distortion available, but you can hear the guitar's actual sound after the mod. On the stock pedal, if you sweep the mid range frequency knob it sounds like you are sweeping white noise. After the mod, it sounds like you are sweeping a parametric EQ or wah pedal. The mod is very expensive to do and includes two of our rare KOT clipping diodes, and a chip change on pedals made before 2008. As on the DS1, Boss copied some parts of our mods, and are using the JRC chip we specified on their newer pedals. The mod also includes most of our silver mod parts from the tube screamer, many upgraded capacitors.
