SWAMP Guitar A/B Amp Switch + Y Splitter Signal Router
Alctron's SW-21 offers guitarists the flexibility of a Y-Splitter, plus an A/B amp switcher in a single unit. Also features a dual input for combining 2 guitar signals into 1.
What to connect where?
Guitars or Instruments are plugged into the PARRALEL inputs. If 2 instruments are connected, both signals are combined into 1. Connect the A and B outputs to different amplifiers.
A/B Amp Switcher
Stomping the A/B function switch, selects which channel output is being used (A or B), allowing you to switch freely between two amplifiers. LED lights indicate which channel is active.
Stomping the Y-split function switch, splits the signal to both outputs, A and B simultaneously. Gain a unique sound by combining 2 different guitar amps, or light up the stage with the full power of your combined rigs.
The switcher can also be used in reverse, using A and B as input channels, allowing the user to hit the A/B switch to select between guitars, or the Y-split to select both. Note that this a completely passive device, and using Y-configurations on certain devices may produce a volume drop.
