CONGRATULATIONS
on your purchase of Tapster, the latest stage in the evolution of our classic tremolo pedal.
To create Tapster, we started with all the seductive vintage tone guitarists love about the T-Rex Tremster. Then we added tap tempo control, so
you can adjust the rate of your tremolo as you play. Finally, we engineered the perfect Subdivision switch to give you even more control
over your sound.
TAPSTER CONTROLS
With its revolutionary tap tempo control, Tapster is built to give you
complete control, even while playing on stage. Start by dialing in some
basic settings:

Set the DEPTH to determine the depth of your volume oscillation.
Adjust the RATE control to get just the right oscillation speed.
Use the VOLUME control to set overall volume. At twelve o’clock, the
volume level is 1:1. Turned all the way clockwise, the input signal is
boosted 15dB.
Choose a SUBDIVISION of the beat (quarter note, eighth note, or eighth
note triplet) to determine your tremolo groove.
Now, once you’ve set your Tapster up the way you like it, you’re ready to
use the TAP TEMPO control:
TAP TEMPO works just like the tap tempo control on a T-Rex delay. Simply tap the switch to the beat, and the rate of your tremolo will sync up
with tempo of song you’re playing.
It couldn’t be easier!
