Roland US-2 for GR-300 GR-700 Analog Guitar Synth

via this auction
"This is the rarest of all vintage Roland guitar synthesizer accessories ever made. According to postings on the web, only 100 of these were ever made... The US-2 is the single most requested item people search for. Almost every day I receive requests for a US-2, or I am asked to build a compatible unit. While the technology in the US-2 is not difficult to duplicate, the parts are. This unit uses two of the male, 24-pin connectors, with two panel mount shells. The only known source for these connectors are actual vintage Roland guitars. So you would have to sacrifice two vintage Roland guitars, or perhaps two LPK-1 kits, plus a GR-300 or GR-100 , to compile all the necessary hardware to build a US-2."

MFB Kraftzwerg Semi-Modular Synth

via this auction
"-semi-modular, fully-analog
-3 VCOs, 24-dB-lowpass-filter
-37 patch connectors
-integrated MIDI/CV-interface
-MSRP: 580,- Euro (about 725 USD)
MFB-KRAFTZWERG is the semi-modular version of MFB’s Synth-II. It trades memory locations and MIDI-control off for 37 patch connectors that allow breaking and modifying the internal routing. Put single KRAFTZWERG components under analog sequencer control or let the whole unit interact with your

existing modular-synthesizer-system.
MFB-KRAFTZWERG works as a stand-alone synthesizer without the need to patch any cable. The classic formation of VCO-VCF-VCA is pre-wired internally, complete with essential modulations. Therefore, you can play the KRAFTZWERG just like any other synthesizer using its MIDI-input. In addition, it may integrate into a full analog environment using control voltages – and benefits, unlike MIDI, from infinite continuous parameter resolution.

MFB-KRAFTZWERG offers a complete set for powerful and versatile synthesis: three VCOs with hard-sync, 24-dB-lowpass-filter with resonance, noise generator, ring-modulator, two envelope-generators, two LFOs and VCA. Technically and soundwise KRAFTZWERG is identical to MFB’s euro-rack-modules."
