This may have been mentioned by others here before, but
I happened to note this cheap and simple ''fat mod'' for the
Boss DS-1 by changing just two resistors, that any of you
can do yourself.

I haven't really seen this video which is about this modification.

The above is commonly discussed in guitar effects forums such
as DIY Stomp Boxes.


The DS-1's circuit diagram, the later models using the M5223 IC,
is attached.



An analysis of the unmodified circuit, with the latest batch using
the NJM2904 IC, is here. In this case, I think the writer made a typo.
R5 is actually the same as R6 in the earlier model. The diagram is
shown without the flip-flop FET bypass switching circuit.
