3630 Parts Upgrade Kit (Archive)
This product is discontinued. This page is just here for archival purposes.
The Alesis 3630 is a budget, stereo compressor that features solid design principles, but is held back by some sub-par components. Replacing these components with our Parts Upgrade Kit improves the 3630's noise floor, bass response, and high-end detail.

- THAT Corp. Blackmer VCA
- Silver mica caps
- Panasonic FR-series coupling caps, chosen by ear
- Larger power-supply caps for improved bass response
- Complete, step-by-step instructions
Note: Make sure your 3630 isn't a "Rev D" or already modified! Open up your unit and check the ICs U2 and U3 (highlighted here). If these ICs say "DBX" you're good to go; if they say "THAT" your unit is a Rev D or has been modded and you probably won't get much mileage out of this kit.
