2 Introduction & Usage

INTRODUCTION

The Termina Transparent Drive is based on the Timmy overdrive pedal from Paul Cochrane, with some

modifications adapted from the Vemuram Jan Ray.

The Timmy was originally released in 2004 and is generally credited for kicking off the "transparent

overdrive" genre of pedals. It does have a two-band tone control, but generally speaking it's not

designed to have much character of its own, instead bringing out the best qualities of the guitar and

amplifier. While it has some similarities to a stripped-down Tube Screamer, there is no trace of the

720Hz mid-hump the Tube Screamer is known for.

The Termina is more specifically based on the Timmy V2 with the clipping diode switch, which is the

same version that was licensed to MXR for their Custom Shop mini version. The Timmy V3 "15th

Anniversary" edition was released in 2019, moving the diode selector inside the pedal and repurposing

the toggle switch as a gain boost.

The Timmy has undergone several circuit changes throughout its run, so there is no single definitive

schematic. This

excellent research article

several collected posts from Paul explaining the changes. The Termina project incorporates all of the

revisions prior to the V3 overhaul, while reversing the travel of the bass and treble knobs so they

increase the frequencies as they're turned up instead of cutting as on the V2.

Please see page 10 for revised licensing terms, which are different from our normal projects. The

original Timmy pedal remains one of the best deals in the industry and we want to encourage as many

people as possible to buy the original if they are able.

USAGE

The Termina has four controls and one toggle switch:

• Drive controls the amount of gain from the op-amp stage that is clipped by the diodes.

• Bass allows adjustment of the pre-clipping bass response of the circuit.

• Treble allows adjustment of the post-clipping treble response of the circuit.

• Level sets the overall output of the effect.

• Clipping selects between three different sets of clipping diodes.
