BUILD NOTES

Tight Rock / Tight Metal modes

The Tight Rock and Tight Metal are very closely related, with only a few small changes between the

two. The Tight Rock came after the original Tight Metal, but some of its features such as the gain boost

switch were back-ported into the Tight Metal for its next revision, which makes a unified version a lot

more straightforward.

Comparing the final revisions of the Tight Rock and Tight Metal, there are only two real differences:

• The mids section after the tone control has different values between the two circuits, both the

Bridged-T mid-scoop and the capacitor value of the mids switch (called "Thrash" or "PlexEQ" when

engaged, depending on the circuit).

• The Tight Rock removes the hi-cut at the end of the circuit and adjusts the gain of this stage slightly.

We've included a "Style" switch to go between Tight Rock and Tight Metal midrange modes. Note that

the "Cut" control also switches between the Tight Rock and Tight Metal settings—so both of these

switches will need to be in the same position for it to be identical to either of the original circuits.

However, the effect of the Cut switch is minimal compared to the Style switch.

Gate design

In the original pedal, the noise gate was tied to the drive control. A dual potentiometer controlled both

the gain level and the gate threshold, so as the gain was turned up the gating was more aggressive.

Separate from this, the gate could be disabled entirely with a slide switch.

In this project, we split out the gate and gain controls, which improves the flexibility as well as

simplifying the control scheme. To mimic the original, just set the gate to the same position as the gain

control. And by turning the gate control to zero, it's identical to the gate bypass switch in the original.

9V/18V operation

The Ember Distortion includes a charge pump for 18V operation as well as an internal slide switch to go

between 9V and 18V mode. If you want to hard-wire it at either 9V or 18V, you can omit the switch by

jumpering the pads as shown:

If you do decide to hardwire it to 9V mode, you can leave out IC4, D9-10, and C34-35. They can just be

omitted entirely—nothing else needs to be jumpered except the slide switch pads.
