The Voodoo Lab Amp Selector’s inputs drive a pair of ultra transparent buffer amplifiers.
These amplifiers input characteristics have been carefully matched to that of a traditional
vacuum tube guitar amp. This insures that your guitar pickups will see the correct load and
therefore sound their best. Using a buffer amplifier is what allows us to drive multiple
amplifiers and a tuner without excessively loading your guitar and destroying your tone.
