A A

Let’s look at some modifications that will have your DS-1 doing your bidding in no time.


Classic JCM-type Marshall Tones:
LOCATION CHANGE TO:
C3 .033µF
R17 15k
C2 1µF
D4 1N4148 Connected in Series to another 1N4148
D5 1N4001 Connected in Series to another 1N4001
C5, C9 1µF
R13 OPTIONAL - Change to 1k for tons of gain, if you do this, also change c8 to 1µF


Modern distortion tones
LOCATION CHANGE TO:
R16 1k
R14 10k
C10 .001µF
C5, C9 1µF films caps (in addition to R15 3.3k)
D4 LED


Vintage distortion tones
LOCATION CHANGE TO:
D5 LED
C3 .033µF
R16 1k
C11 .001µF


If you like the general sound of the DS-1 but are looking for less highs and more of a tonal range change C10 to a capacitor with a larger value. Stock is .01”F for a frequency roll-off of 7.2kHz.

Less shrill highs
LOCATION CHANGE TO: FREQUENCY ROLLOFF:
C10 .015µF 48kHz
C10 .022µF 3.2kHz
C10 .027µF 2.6kHz
C10 .033µF 2.1kHz
C10 .047µF 1.5kHz


All in all, the Boss DS-1 Distortion is an inexpensive pedal that can rival many of the best boutique pedals simply by changing the circuitry a little. While this may seem difficult, technical and out of reach, it really is very simple if you know what to change and where to change it. I hope that I’ve given you the knowledge and courage necessary to change your pedal from a mouse into a monster. Happy soldering!
