Introducing the compact 2-in-1 pedal, the 25kΩ edition. AMPERO PRESS 25kΩ Edition compatible with EXP impedances from Strymon, Kemper, Fractal, and more HOTONE has added the AMPERO PRESS 25kΩ Edition, a compact 2-in-1 passive volume/expression pedal that supports an expression impedance of 25kΩ, to its lineup. It can be used with products with an expression impedance of 25kΩ, including Strymon, Kemper, Fractal, and Line6. The AMPERO PRESS 25kΩ Edition has the same functions as the AMPERO PRESS (10kΩ), and can be used as an external expression pedal to control many control functions externally, as well as being used as an independent volume pedal (passive). In addition to 1/4" mono input and output, it also has a dedicated 1/4" TRS jack for expression, which can be connected to the EXP IN of an external device using a TRS cable. Vol and EXP can be used simultaneously, and impedance patching allows for 100% accurate EXP control. INPUT: 1/4" mono input jack EXP OUT (Expression Output / 25kΩ): This is a 1/4" TRS jack dedicated to expression. Connect it to the EXP IN of an external device with a TRS cable. Check the recommended EXP impedance of the connected device. Vol and EXP can be used simultaneously. OUTPUT: 1/4 mono output Potentiometer Impedance VOL Volume: 100kΩ EXP Expression: 25kΩ Size and weight: 81mm (W) x 162mm (D) x 51mm (H) Weight: 430g
