The PURE Clean Boost is my take on the classic MOSFET boost by Jack Orman, and it provides up to a whopping 35dB of clean signal boost without coloration or signal distortion. But don't just think of the PURE Clean Boost as a simple volume increasing effect, because it can do a lot more. Here are a few cool things you can do with the PURE Clean Boost:
The most basic use of the PURE Clean Boost is to simply provide an overall volume increase by placing it last in your effects chain. Set the PURE to whatever volume you'd like, and kick it on when the time is right — you'll then simply get more of your sound.
You can also use the PURE Clean Boost to crank more overdrive out of your already overdriven tube amp. Set the PURE to near unity volume, and when you kick it on, your amp will get a boost that will be just enough to add some extra gain to your signal — without a noticeable volume increase.
Another use for the PURE Clean Boost (and how I use mine) — is to "cook" your amp tubes. The goal is to get your amp tubes running at maximum efficiency by pushing them right to the point of clipping/overdrive. You do this by turning up the PURE until you begin to hear it causing your amp to go into overdrive, and when the breakup starts, back off the PURE just a little bit — and now your tubes are fully "cooked" to maximum efficiency. In this scenario, you'd leave the PURE Boost running all the time, so if you want a volume boost as described above, just add a second PURE Clean Boost to your chain.
Lastly, the PURE Clean Boost works great as a line buffer if you need to maintain your signal over long cable lengths.
The PURE Clean Boost sports an etched finish that's hand sanded and polished to a high shine, and sports metallic black paint in the recesses.
As with all my effects, only the finest quality parts are used: cast aluminum shells, Switchcraft jacks, individually selected transistors, carbon resistors, high-end capacitors, and personally designed plate-through PCBs. The PURE Clean Boost is true bypass, sports heavy-gauge wiring, a 9-volt center pin negative (BOSS style) DC jack (18v is supported, too), and an internal battery clip.
