Keeley The Boss DS-1 Distortion Guitar Effect

Boss DS-1 Distortion Intro
This guide will help you begee familar with the different versions of the Boss DS-1 that were made along with some regemended settings, including Joe Satriani's. The DS-1 can be had for a very low cost making it a big seller, the rare 'Made in Japan' Black Lable DS-1's will cost you double or triple of the brand new Tawian version. I like the Tawian after it has been modified, I use Keeley Electronics and can really hear the difference of a stock DS-1 vs a modified unit. There are alot of folks who can do their own mods and save money as well. The stock DS-1 is fine too and is fun to get new sounds out of you guitar and amp.
The Boss DS-1 Distortion is a great low cost unit that really allows your playing dynamics to shine. If your lucky enough to find a Black Lable MIJ version it will cost you more but I really like the sounds it produces. I also like gebining this effect with others such as a Boss OD-3 and Boss BD-2 this technique know as "Stacking" allows a greater choice of tones.
This is truly a classic distortion pedal. It produces a distortion sound with a hard edge and is known to have a very low noise level gepared to other distortion pedals. Many people swear that the older "Made in Japan" models sounds better than the newer "Made in Taiwan" models. The DS-1 has over the years been used by a lot of great guitar players. Steve Vai and Joe Satriani are two players who has voiced their praise over this pedal. Steve use's a Robert Keeley Modified DS-1 and Ibanez TS-9.
Modified DS-1's
I have the Keeley modifed DS-1 which is called the Ultra Mod and it is a great unit for hard rock or you can back off the Distortion setting raise the volume and play the blues ~ Jimi Hendrix or Jimmy Page style. I also own the Japan version which has the black label and a Silver Screw which means this was one of the first one's made in Japan. It has a greater amount of distortion available than the Taiwan or even the Keeley models and the distortion is smoother throughout the range.
Here is the skinny on modification; With a diode Toggle Switch you have the DS-ULTRA! Huge tube like tone, switch back and you have the classic Seeing Eye Mod (SEM) version of the pedal for high gain, tube like distortion!
* Extra mods to increase the distortion range at maximum settings.
* Mods to correct the bass response and give you a fuller, more powerful tone. Perfect for Strats now with this mod!
* Larger Silver Mica Cap installed to further smooth the overall sound.
* gees with Cool Knobs!
* Toggle Switch Up - Our Standard Seeing Eye Mod.
* Toggle Down - Adds another LED to the clipping circuit for a Large Fat Tone.
The Extra LED increases the volume output of the pedal a bit, great for using the DS-1 as a pre-amp to push the amp or to fine tune a low distortion sound on the unit. The way we engineer the mod, it is has increased 2nd order harmonics and tube-like qualities.

Version differencesThe design of the DS-1 was changed somewhat around 1994. The main change was that the Toshiba TA7136AP opamp was replaced with the Mitsubishi M5223AL. The DS-1 has also gone through a number of cosmetical changes. The earliest version had a silver thumb screw and the D in DS-1 placed directly underneat the t in Distortion. The D in DS-1 soon ended up under the i in Distortion where it remains today.
Boss Guitar Effects Guide Book vol.11 (1995):
The DS-1 provides a harder distortion effect for guitar and keyboard sounds.lnstead of toneless, fuzzy distortion, the DS-1 faithfully reproduces all the subtle nuances quiet to screaming loud. The onboard Tone Control allows you to tailor the overall sound to your liking.
Mild distortion: This setting gives you mild, mellow distortion. For best results, use your pickup closest to the neck. (Fig. 1: Tone 0, Level 4, Dist 4) Hard distortion: For this setting your should use your bridge pickup. When the TONE level is raised, highs are strengthened and a powerful distortion effect results. Adjust the amp and guitar volume carefully to avoid excessive effect depth. (Fig. 2: Tone 4, Level 4, Dist 7) Joe Satriani Settings ~ I got to meet and talk with Joe Satriani after a show about the settings he prefers on the DS-1 and if using a Japan model he likes the Tone 10, Level 12, Dist 2 on the Taiwan model he regemended to me that the Tone 9 and Dist on Max helps that model get closer to his sound. Joe has gee out with his own version of the DS-1 it is the Vox Saturator and it has alot of cool features. I bought one right away and gepared it to my MIJ DS-1 it has a slight amount more of distortion available and sounds almost like a DS-1. It has a more switch that is suppose to take it over the top for solo's but for me it just muds up the mix. The modified DS-1 can clean up alot better than the Vox by far and so I'm still using the DS-1. Steve Vai also came out with a Ibanez two-stomper that basiclly does a DS-1 and TS-9 sound it looks cool and sound fine so if your a fan boy get one. I still like my Keeley TSDX-9 Flexi with a DS-1 for my Vai sounds and think for the low cost of a DS-1 you can save a bunch of money and still have enough to buy the new Five CD set by Mr. Vai called Naked Tracks and use them to jam along with your DS-1, oh don't forget the delay! ;-
