COLORSOUND: Treble Booster, Steve Williams (partial trace)

Colorsound treble booster SW v1a 63b78e94114f

So there are a few bits missing, but if you are familiar with treble boosters, I’m sure you’ll work it out.  Being a small and simple circuit, it’s a good candidate for breadboarding. The filter pot is your standard input blend, probably similar to the values that Steve Williams uses in his Pigdog Competition Special … Read more

COLORSOUND: 1971 Overdriver

COLORSOUND Overdriver vero layout v1 5be53da30ae0

The Colorsound Overdriver / Power Boost family went through a few different versions over the years. This layout is for the classic 1971 9V Overdriver version – essentially the 9V successor to the earlier 18V Power Boost, with the same basic three–transistor topology but set up for a standard single-supply pedalboard. It makes a huge, … Read more

COLORSOUND: Sakata Hybrid One Knob Fuzz Box

COLORSOUND Sakata one knob fuzz v1 d7444b6b8d40

Macari’s often release pedals that are minor variations on the same circuit – in this case the “Sakata” Colorsound hybrid one knob fuzz has quite a few value changes compared to the previous hybrid they released, which was closer to a stock fuzz box.   Macari’s describe the Sakata as being tuned closer to a MK1.5  I … Read more

COLORSOUND: Hybrid Fuzz Box

COLORSOUND Hybrid fuzz box vero layout v1 4db4f389a541

The Colorsound Fuzz Box has to be one of my favourite fuzz circuits, due to its simplicity and reliable results.  It’s very much a one trick pony, but if you just want a nice thick fuzz, this will to that trick quite well.   The original silicon circuit is said to be a Dick Denny design, … Read more

COLORSOUND x D*A*M: Fuzz Sound

COLORSOUND DAM Fuzz Sound 2 knob 015 vero layout v1 6576df17b251

Following on from the previous post, this is the D*A*M version of the Colorsound Fuzz Sound.  Thread on the D*A*M forum can be found here.   Basically take a D*A*M Fuzz Sound, and change the Fuzz pot to an internal trimmer.  Unlike the regular Park 2 knob with a large 25u coupling cap between the darlington … Read more

COLORSOUND: Jumbo Tone Bender

COLORSOUND Jumbo Tone Bender vero layout V1 dd105d2f5dbe

Surprised that I hadn’t done a standard vero layout for this earlier…  The Colorsound Jumbo Tone Bender is just a Big Muff missing some diode clipping and the last boost stage (the lack of diodes in the first clipping stage makes up for the lack of boost). They share nothing in common with their predecessors of the … Read more

COLORSOUND: Tone Bender Distortion

COLORSOUND Tone Bender Distortion vero layout e60d989a6629

I did a point to point layout for this some time ago, which was actually my first post for this blog.  Full description via the link above.    The Colorsound Tone Bender Distortion is more distortion than bender – there are zero similarities between a MKI, MKII or MKIII bender and this circuit.  COLORSOUND TONE BENDER DISTORTION – … Read more

COLORSOUND: The Yellow Hybrid OC140 Tone Bender by Jake Rothman

COLORSOUND hybrid tone bender 015 vero ea1523c6e193

All the details are listed in the previous post – this is a 0.15″ version of the yellow Colorsound Hybrid Tone Bender.   I did the previous layout on standard size vero, and after using 0.15″ vero and tag board on a lot of builds recently, it just seems very tiny now, so I did … Read more
