Product Description

The Amp Select pedal is extremely versatile and opens the door to a variety different amplifier and pedalboard configurations. For example, when placed in front of a stereo recording looper, the recording and playback functionality of the looper is expanded.

Typically, the Amp Select Pedal is used at or near the end of the signal chain and can be easily configured to operate in either Amp Select (A/B) or Stereo mode via the footswitch. In Amp Select mode, the pedal board has the ability to switch back and forth between two amplifiers, with each amplifier driven from its own unique input source (Ain, Bin).

Given that each amplifier is driven from its own unique input source, each amplifier channel can be tailored to a specific tone or purpose (if desired). For example, one amplifier channel could be setup for lead tones while the second amplifier channel is optimized for rhythm. Another pedal board configuration might be where one amplifier channel is setup for Acoustic guitar while the second amplifier channel is setup for normal electric guitar. Or the two amplifier channels might be configured to produce a specific stereo tone when both channels are played together in Stereo mode. Numerous pedal board configuration options are possible.

The Mode Select foot switch is used for switching between Stereo or A/B mode. In Stereo mode, a typical configuration might be where a “Stereo” effects pedal is used in combination with the Amp Select pedal, or alternatively where Delay and Chorus has been wired into Channel B, with Channel A wired for a clean tone. This configuration would have the benefit of producing a well-defined, articulate stereo tone because the original source remains fully intact in one channel.

In addition to the operating modes described above, placing the Amp Select pedal in front of a Stereo Recording Looper allows each input channel of the Looper to be recorded separately, whereby expanding the functionality of the Looper. For example, when the Amp Select pedal is placed in Amp B Select mode, and the Looper is placed in record mode, only the B channel will be recorded. Likewise, if the Amp Select pedal is placed in Amp A Select mode, only the A channel will be recorded. When the Amp Select Pedal is placed in Stereo mode, both input channels will be recorded as per normal Looper operation.

In a similar fashion, when the Stereo Recording Looper is placed in playback mode, the Amp Select pedal will selectively control which channel(s) (Chn A, Chn B, or Both) will be allowed to pass on top of the Looper recording. For example, when the Amp Select pedal is placed in Amp A Select mode, only Channel A will be allowed to pass on top of the Looper recording playback. In Stereo mode, both channels will be allowed to pass on top of the Looper recording playback.

Another useful feature on the Amp Select pedal is two 9vdc Boss style connectors (center ground) are provided for powering the LED status lights, but only one is required. Either connector can be used to power the LED status lights, which leaves the other connector free to pass on 9vdc to another pedal.

When the Amp Select pedal is used in combination with the Stereo/Mono pedal, the pedal board is capable of operating in seven different amplifier configurations, including Mono and Dual Amp.
