The Free The Tone SILKY GROOVE SG-1C-CS is a compressor pedal built by the company's Custom Shop, produced in a limited run of 150 units to commemorate the release of the SILKY GROOVE in the standard series1. Free The Tone says it inherits the sound of the Custom Shop series SILKY COMP and refines it into a more natural, smoother sound1. It is designed for both guitar and bass, compressing without sacrificing the instrument's sound character or the fine details of finger touch and picking nuance1.

Controls and how it works

The SG-1C-CS keeps the control layout simple: an ATTACK control and a SUSTAIN control for the compression function. Free The Tone designed both with gentle curves that avoid abrupt changes, making them easier to dial in than controls that bunch up their response at one end of the sweep1.

The pedal also carries Free The Tone's HTS (Holistic Tonal Solution) circuit, which the maker says prevents degradation of sound quality even when the effect is off1. For a player, that means the pedal should not color the signal when bypassed.

Power and connections

The SG-1C-CS offers two power options, which is less common among current compact pedals1:

  • A DC 9V input jack for an AC adapter1
  • A 9V size 006P type battery1

Connections are two 1/4-inch standard phone jacks, one input and one output1.

Where it came from

The SG-1C-CS descends from the SILKY COMP line. The original SILKY COMP / SC-1 ended production in 2018, a discontinuation Free The Tone described with regret21, and the SILKY COMP SC-1-CS Custom Shop version was also discontinued that year3. The Silky Groove SG-1C in the standard series followed, and the SG-1C-CS was built as a Custom Shop commemorative model marking that release1.

As a Custom Shop model limited to 150 units1, the SG-1C-CS is a limited-edition pedal rather than a standard catalog product.

Questions

How many Free The Tone Silky Groove SG-1C-CS pedals were made?

The SG-1C-CS is a FREE THE TONE CUSTOM SHOP model limited to a production run of 150 units. It was built to commemorate the release of the SILKY GROOVE in the standard series, and it comes in a Custom Shop model limited package.

Does the SG-1C-CS run on a battery?

Yes. Free The Tone lists the SG-1C-CS as compatible with a 9V size 006P type battery, alongside AC adapter power through the DC 9V input jack. Many compact pedals have dropped battery power, so this is worth knowing if you run it on a board or prefer battery operation.

What is HTS circuitry in Free The Tone pedals?

HTS stands for Holistic Tonal Solution. It is a circuit Free The Tone builds into the SG-1C-CS to prevent degradation of sound quality even when the effect is switched off, so the pedal does not color your tone in bypass.

Is the SG-1C-CS based on the Silky Comp?

Yes. Free The Tone says the SG-1C-CS inherits the sound of the Custom Shop series SILKY COMP and refines it into a more natural, smoother sound. The original SILKY COMP / SC-1 ended production in 2018.

Can the SG-1C-CS be used with bass?

Yes. Free The Tone describes the SILKY GROOVE as designed for both guitar and bass, compressing without robbing the instrument of its sound character or the fine details of finger touch and picking nuance.
