Hello, Effects Fans!
Today we announce our new OverBoost module. It compares to a family of boost pedals from Xotic Pedals. The OverBoost comes in 8 different base configs that compare to the Xotic BB Preamp (current model), Xotic BB Pream AT (Andy Timmon, original models), Xotic BB Preamp Bass, Xotic BB Preamp MB (Mids Boost Custom Shop model), Xotic BB Preamp Comp (Compression Custom Shop model), Xotic AC Booster, Xotic RC Booster, and Xotic RC Booster Bass.
The RC, AC, and BB configurations cover a range of clean to dirty boosts. The RC or "really clean" covers the space from clean to gritty to mild overdrive. The AC starts at an "almost clean" level and goes up to crunchy overdrive. The BB, aiming for the range of a Marshal Bluesbreaker amp, covers the range from cleanish/gritty to full overdrive. Most guitar and bass players have probably had the opportunity to try at least one of the pedals in this family. They are great boosts at reasonable prices. Where they really shine is in giving you fine control over how much you push the front end of your amp, especially if you have a tube amp. Depending on which you choose and how you dial in the Volume and Gain, you can get a nice, fat clean boost that gives you "more of what you've got", or you can push your amp into varying levels of break up, or shove your amp over the edge into heavy, chunky overdrive or distortion.
The circuit is similar to its tone-cousin, the Ibanez Tubescreamer. But it has some important differences. The BB replaces the Tubescreamer Tone control with a fixed resistor, adding a new tone stack after it that gives you great Bass and Treble controls. These two controls also allow you better control over your mids. The MB version puts a Mids control back into the Tubescreamer-like tone stack in place of the fixed resistor, in addition to providing the additional Bass and Treble controls. Different types of clipping between the original/AT version and the current version yield similar but slightly different gain levels, sometimes described as different levels of compression. The AC and RC versions leave out the old Tubescreamer tone stack completely, replacing it with the new Bass/Treble tone stack. The AC and RC versions also differ in clipping configurations to yield cleaner base tones than the BB configuration, with the RC configuration being the cleanest of the three.
The new tone stack is important to dialing in that level of clean to dirty boost that you want. At different levels of dirt, you will likely need to adjust different frequencies to get the tone balance you want. A single Tone control may not be sufficient for that level of fine-tuning. The Bass/Treble tone stack in this circuit should do the trick, especially if you opt for a configuration that includes the Mid Boost control. An optional second channel will let you switch between two different Gain settings.
