Microcontroller-controlled MIDI switcher for channel switching or loop switching. Operation can be performed either via MIDI or a footswitch (momentary switch).

!!! UPDATE !!! With the May 2019 update, the following adjustments were made to the module:

• The large relay board has been removed and is no longer included in the kit, as a wide range of different relays with carrier boards is now available, offering much more flexible applications.
• The documentation has been consolidated and is available as a PDF download directly with the kit.
• The microcontroller with the firmware is no longer included in the kit and must be ordered separately depending on the desired version.

These changes allowed us to offer the kit in a more universal, flexible, and cost-effective way. More short information and software on the >>TT-Midi-Switcher project page

Electro-Harmonix has released a low noise, low microphonic version of the 12AX7 that meets all specifications required for the tube to be designated 7025. The original 7025 tube was a 12AX7 that was tested and selected for the lowest noise and microphonics for use in the critical first preamp stages of amplifiers where noise and microphonics could be an issue. In order to ensure that the 7025 specification is consistently met, Electro-Harmonix has redesigned the structure of the 12AX7 and has implemented construction techniques to ensure the absolute lowest noise and microphonics possible. In all samples tested, noise and microphonics could not be detected.

The Electro-Harmonix 7025EH has a mid-range that gives clarity and definition to the sound and a smooth top end for warmth and balance. With these characteristics, along with the exceptionally low noise and low microphonics, the Electro-Harmonix 7025EH will work equally well in vintage and modern high-gain guitar amplifiers, as well as sensitive phono preamps.
