INTRODUCTION

The Perelandra Boost / Overdrive is a recreation of the Xotic BB Preamp, a flexible tone machine that

lets you go from a clean volume boost to a nice smooth overdrive with a 2-band EQ to shape the tone.

The BB Preamp is very similar to the Ibanez Tube Screamer, but with an active Baxandall tone control

added before the output buffer so that the treble and bass can be independently boosted or cut.

In fact, if you look at the schematic for the BB Preamp, you can see that the original Tube Screamer tone

control stage is left intact, but with the tone knob is fixed at 5% rotation (i.e. almost fully to the dark side

of the control) by using a 1k and a 19k resistor. The main difference between the BB Preamp and the AC

or RC Booster is the presence of this Tube Screamer tone control stage to shape the tone going into the

Baxandall EQ.

USAGE

The Perelandra has four controls:

• Gain controls the amount of gain from the op amp that is fed through the feedback clipping diodes.

• Treble is one half of the Baxandall tone control, allowing you to boost or cut high frequencies.

• Bass is the other half of the Baxandall tone control, allowing you to boost or cut low frequencies.

• Level sets the overall output of the effect.
