This is a killer preamp and a killer toy too.
The business side is a top-end three channel preamp with bright switch and 128 preset slots to which to memorise sounds and levels. Being a Soldano, the clean sound is ok but the overdrive is out of this world.
On the fun side, each preset is recalled mechanically through the movement of the unit’s motorised knobs. you can even programme real-time changes (and accompanying knob movements) via midi, so you can move the dials with a footpedal.
Even better, this one is converted for European voltage so there’s no need for a weighty external step-down transformer. Apparently only a couple of hundred of these were made, so they’re pretty scarce. This one came from coastal Italy, of all places.
