via this Reverb listing
Demo in the listing previously posted here.
"In perfect working condition. Includes original power supply and box.
The MFB Nanozwerg is a compact monophonic analogue synthesizer that packs serious versatility into a tiny footprint. It features a true analogue VCO with selectable triangle, sawtooth, square, and pulse waveforms, a sub-oscillator or noise generator for added depth, a multimode 12 dB/oct analogue filter (lowpass, highpass, bandpass, notch), and full modulation capabilities with an LFO (including “one-shot” mode), ADSR envelope, and CV/Gate or MIDI control. Despite its modest size, the Nanozwerg handles basses, leads, sequences, or noise/FX sounds, and thanks to its VCF and VCA routing plus audio input, it can even be used as an external filter box or effects processor when processing other sources."

Xiphonics picoTracker Advance Portable Music Workstation
Note: links to listings are affiliate links for which the site may be compensated.
"Only at Perfect Circuit:
Xiphonics picoTracker Advance Resembling a Matrix GameBoy and slightly larger than a passport, this portable music workstation is a portal to eight-track composition with muscular sequencing and a suite of instruments and effects. We're the exclusive North American dealer for the pico Tracker Advance: give it a peek and level up your downtime."
You can find some demos in previous posts here.
"The Xiphonics picoTracker is a portable tracker that offers a premium experience for on-the-go music creation. From the 4", 720x720 color display to the incredible tactile keys, you get sensations that will make it hard to put this device down—nor will you need to with an incredible six hours of battery life. The software and key combinations are easy to use: inside of a few minutes you'll be up and running creating some interesting textures and driving beats. Load in your own samples on the included SD card or sample directly in the device using the internal mic or 1/8" TRS line input.
When composing, you have access to eight stereo channels with sixteen steps for chaining Phrases, which themselves have sixteen steps available to program. When programming phrases, you have access to the notes, step behavior, instrument selection, and effects. With this combination you can get lost weaving together intricate rhythms and stitching together disparate textures to construct nuanced, full-ensemble arrangements. There's also a Groove section which allows you to adjust the timing with an incredible amount of precision, allowing for a natural—or unnatural—rhythmic feel. One of the most interesting options with the picoTracker is the Table screen, which lets you create complex effect sequences that can be looped, played once, or can jump between different sections. These Tables can be triggered via an Instrument or a Phrase.
When you've finished your piece, or want to take it into another device or DAW, you can render out a Mixdown or individual stems right on the device itself. Indeed, the Xiphonics picoTracker behaves much like any other tracker, but the options presented by the interface and the physical interaction really has this lovely little friend punching above its weight.
PICOTRACKER ADVANCE FEATURES
Battery powered tracker
48MB Internal sample memory
720x720 4" Display
Internal instrument and external MIDI tracks
High-quality chassis
Satisfying keys
Internal Speaker

Custom White Roland Juno-106 61-Key Programmable Polyphonic Synthesizer
Note: links to listings are affiliate links for which the site may be compensated.
via this Reverb listing
"Custom Roland Juno 106 serviced, painted, and modded by the synth spa in late 2017. This Juno 106 is super clean, works perfect perfectly, and is one of a kind. The color is cream and all the graphics, program lights, and mod wheel are all custom. Synth spa also socketed the main processor so it’s easily removed if you should ever decide to do the kiwi. The sides are Custom too but kind of wish I would’ve gone with a matte/satin finish because they’re a little overly glossy(see pictures,) but still nice. This synth is in great shape and playsas it should. If you’re familiar with this synthesizer, it’s the voice chips that can go bad but these were fully restored when this synth was customized and should continue to stay strong for a long time."
