Amptweaker Accomplish 'Sustain without Compression' with PressuRizer

Sustain without compression...a common suggestion Amptweaker receives that means “don’t mess with my attack.”

The Amptweaker PressuRizer compressor accomplishes this in several unique ways and includes a built-in output FET limiter/booster, making this a powerful clean-tone tweaker. Using parallel studio-grade compression with wet/dry blend, and some unusual side-chain variations, it varies from smooth compression that limits the initial "whack" to a dry-blended approach that adds compression after a short delay.

The Bloom switch (fast/off/slow) rewires the side-chain detector so the signal compresses and then grows. When blended with dry, the result sounds normal at first, and then blooms like a great Les Paul. The tone only affects the compressed signal and boosts highs to cut through, or cuts midrange to help match the blooming tone to the dry. The limiter switch adds a FET booster after the blend, and can be set to soft for barely limiting, hard for a slightly broken-up sound, or off for no limiting. This FET limiter has a very rounded breakup, similar to output tubes.

Since many always leave their compressor on, the PressuRizer has a cool 2-step footswitch. Normally it’s a true bypass on/off switch, but if you press and hold the PressuRizer's switch, it locks the compressor on, and then tapping kicks in another boost knob on the side of the pedal. So, you can get a 1–2 punch with a single-button pedal!
