Vacuum Tube Exchange (VTeX)

Vacuum Tube eXchange (VTeX)

Only Vacuum Tubes deliver truly BIG Tone; but did you know they will also provide unparalleled flexibility, too?

In less time than it takes to tune a guitar, SWELL effects can be customized to fit your specific musical needs by a Vacuum Tube eXchange (VTeX).

G-TOD Example:

  • Simply exchange the stock 12AX7 with a 12AT7 in the G-TOD and the amount of available gain and compression will be decreased. In this example, a high-gain overdrive will now become a mid-gain drive pedal.

G-Drive Example:

  • Simply exchange the stock 12AY7 with a 12AT7 in the G-Drive and the amount of available gain and compression will be increased. In this example, a low-gain push drive will now become a mid-gain drive pedal.

Tube Gain Chart

  • 12AX7 – 100%
  • 12AT7 – 60%
  • 12AY7 – 44%
  • 12AU7 – 20%

Tonal or overall character changes are possible too; add mids, reduce highs, etc.—the possibilities are almost endless.

Premium, NOS, and original Vintage Tubes—you choose how you want to customize your sound.
