We recently added an option to our FlexBoost board. That board is used to build several of our boosts, including Trail Boss, Queen Boost, Treble Boost, Sonic Boom, Bass Boost, Woody, and others. The option allows us to add a simple Tone control to some of those other boosts. The Tone control option is nice, and enables us to offer our Crema Boost, which compares to the Keeley Java Boost. We have now added the Crema Boost to our product list.
We just built a Crema Boost on our new boards. It was a standard build, with no extra features. We did use an OC42 transistor instead of an OC44 in our test build. We had both available, but we decided to go with the OC42 in our demo module so people could try out another transistor type. The Crema Boost is very similar to the Trail Boss, which compares to the Dallas Rangemaster. We already had some OC44 builds of the Rangemaster in our demo racks. If you play our demo modules, you could compare the two transistor types in those similar modules. There’s not much difference between the two when the transistors have both been selected carefully.
The Dallas Rangemaster was a treble boost designed to brighten up a Les Paul paired with a Marshall amp. It was particularly intended to push a Marshall tube amp into distortion. If you use it at lower amp levels, or with a brighter setup, it won’t sound so great. The Crema Boost has a switch to allow you to select between a full range boost, treble boost, or mids boost, which makes the module sound better when you aren’t playing through a Marshall on the edge. Crema is the smooth, rich, tan foam on your espresso that gives it its character and makes it more than just some strong coffee. The Crema Boost does something similar for your Les Paul and Marshall clean tone on the edge of breakup. Or with the flick of a switch, it works for a different guitar/amp combination.
We’ve compared our Crema Boost to the Java Boost in our test pedals collection. Although the transistors are different types, with probably different gains and leakages, and probably different biasing, the two sound about as close to the same as two germanium circuits can. Grab your Les Paul and your Bluesbreaker amp and get your Clapton Beano tone going!
