Frequently asked questions about the SVpre:

How is the SVpre installed?: The installation is very simple. Install one connector and solder 3 wires.
Because of the high voltage associated with tubes, installation needs to be performed by a
qualified service technician.
Will I really be able to notice a difference in the sound?: Yes, there is a huge difference in feel and tone.
If you feel like something may be missing when you play your Spider Valve, SVpre can bridge the gap.
Will installation of the SVpre void my Line6 warranty?: Yes, unfortunately any modification to your amp
will void the warranty. However, we feel that the advantages greatly outweigh the cost.
What are the “push” modes?: “PUSH” offers 4 pre-set gain selections on the SVpre. This allows you
to customize your amp based on your playing style. If you like the way you Spider Valve sounds but
want it to feel and react more like an actual tube amp, leave the SVpre in “stock” mode. If you crave
tube gain and want to depend less on digital distortion, you can choose from “yellow push” ,
“orange push” , or “red push.” Choose wisely.
Why did you make this thing?: We at strymon are fans of Line6. We saw great potential in the Spider
Valve amp and in experimenting with it, we found adding a tube before the digital modeling and
processing greatly improved the playing experience. We feel that the full potential of the amp is only
realized when you wrap that dsp modeling in a warm, fuzzy tube blanket. :)
