CONGRATULATIONS
on your purchase of SpinDoctor2, the ultimate analogue overdrive preamp from
T-Rex Effects.
Whether you use it as an intelligent distortion pedal or a programmable preamp for
gigging or studio recording, SpinDoctor2 gives you a wealth of options.
Read this manual carefully to learn how to make the most of SpinDoctor2. The better you know it, the more it will reward you with its amazing breadth of tube-driven
tone.
USING YOUR SPINDOCTOR 2
The main controls for your SpinDoctor2 are located on the top of the unit. They
include:
4 CHANNEL BUTTONS: Select the channel (A, B, C, D) you want to play through or
edit.
GAIN knob: Turn it down for a clean tube sound – crank it up for more overdrive.
TO USE YOUR SPINDOCTOR 2, START BY PROGRAMMING YOUR 4 CHANNELS
Here’s how it’s done:
Use the channel switches (A, B, C and D) to select a channel.
Set the GAIN, TONE and LEVEL controls for the channel you’ve selected (use the
LEAD button to add extra boost).
Hit STORE to save your settings.
Repeat this process for each channel, and you’re ready to switch between them.
INPUTS AND OUTPUTS
Your SpinDoctor2 features all the input and output options you need to get the
perfect sound in any situation.
Plug your guitar into the INPUT jack, and run a cable from the OUTPUT jack to your
combo amp or power amp, or from the SIM. OUT to a studio mixer or your computer’s AD converter.
TONE knob and BASS, MID, TREB, PRES buttons: Press a parameter button and use
the knob to set the level.
LEVEL knob: Control the channel’s overall volume.
LEAD button: Hit this for even more overdrive gain.
STORE button: Press to store your channel’s settings.
When running SpinDoctor2 into a combo amp, make sure the HI/LOW button on
the bottom of the unit is in the “up” position (this lowers output).
If you use SpinDoctor2 as a preamp – either with a power amp or running into a
mixer/AD converter – keep the HI/LOW button in the “down” position.
SpinDoctor2 makes a great preamp for recording guitar in the studio. When you’re in
the studio, try using the SIM. OUT to simulate the sound of a real speaker cabinet.
Use the SIM. LEVEL knob to adjust volume, and the FREQUENCY button to define
the character of your “cabinet”.
