WARNING! — The OPA2134PA opamp, of which are included in many of my kits, is currently extremely hard to find. Mouser and Digikey are currently out of stock with none exspected until 2023. I have hundreds in stock. BE CAREFUL BUYING THE OPA2134PA ON EBAY. THE MAJORITY ARE FAKE! Manufacturers in China are rebranding cheaper opamps and selling them as OPA2134PA opamps. I test all my OPA2134PA opamps I buy. You can easily test whether a OPA2134PA has been rebranded. Do this, take some Acetone on a Q-tip and rub across the lettering of the opamp. If it is Fake the ink used to print the labeling will desolve into the Q-tip.
I hope you enjoy the CS-3 Noise Decimator Mod. This mod absolutely Decimates the noise of the stock CS-3. The two new opamps kill noise and add much needed clarity to the circuit. The other request I constantly get is people want more bass and warmth. The Tone Knob mod has accomplished that and more. The tone sweep is now much more responsive and adds a certain sweetness to the CS-3.
Together all the mods work to give your CS-3 near studio quality compression at a very reasonable price point. You’ll want to leave your CS-3 on all the time. I never turn mine off. Enjoy!
IMPORTANT — Boss has started using surface-mount components on some of their new pedals. I’ve created a page to help you determine if your pedal is moddable. Read about it here.
Great for Guitar & Bass!
