1 Project Overview

2 Introduction & Usage

INTRODUCTION

The Cirrus Dynamic Overdrive project is a clone of the Ibanez ST-9 Super Tube Screamer, an incredibly

rare Tube Screamer variant only produced from 1983-84. It's essentially a stock Tube Screamer with an

added stage, a semi-parametric midrange control that delivers a fixed boost at a variable frequency.

The ST-9 was introduced near the end of the original run of the 9-series and was quickly discontinued

along with the rest of the series. However, the circuit reappeared the next year in 1985 as part of the

Master Series, this time called the STL Super Tube. This series had broader distribution and so the STL

version is much easier to find.

Curiously, the STL version made one major change to the circuit: transplanting the mid-boost stage after

the clipping instead of before, where the original ST-9 put it before. There are no other changes to the

circuit, but there is a notable difference between pre-clipping and post-clipping mid boost.

The Cirrus project incorporates both versions, allowing the mid-boost section to be placed either before

or after the clipping using an on-board slide switch. (This is the main update from the original 1590B

version of the Cirrus, which uses on-board jumpers to set the mid-boost location but can't be toggled.)

In addition to the mid-boost slide switch, the Cirrus also includes a clipping diode switch so you can

select between three different sets of diodes.

USAGE

The Cirrus has the following controls:

• Drive controls the amount of gain in the op-amp feedback diode clipping stage.

• Bite is a semi-parametric midrange control with fixed boost.

• Tone controls the treble response of the effect. The center point (12:00) is flat. When turned to the

left, it cuts treble, and when turned to the right, it boosts treble.

• Volume controls the overall output of the effect.

• Clip (toggle switch) selects between three sets of diodes: 1x silicon (stock), 2x silicon, and LEDs.

• Mid EQ (slide switch) selects the location of the mid-boost section, either before the drive stage

(ST-9 mode) or after (STL mode).
