Unfortunately, this is no longer available, but perhaps the Related offers may be of interest.
huendeskes Features: - 2 series loops - 2 channel switches (I used it with a Laney VC50 for switching between the two channels, and for turning the +drive on/off for both channels, stereo jack - DIN5 cable, I can provide it if needed - DIY: it might not work the same way with other amps!) - 9V DC adapter connector, center negative (I cannot provide the adapter, I used it with a central power supply)
The functions can be switched on/off programmably, I controlled (and programmed) it with a GT-100.
If needed, I can send a video of its programming (with GT-100) and its use with my own amplifier.
Can be tested and picked up in Kaposvár, but I can also ship it. If paying in advance, the price includes shipping costs.
