Additional Tone Tweakers Listings
"This unit was meticulously refurbished over approximately 16 hours, resulting in an instrument that works better than the rest...and is justifiably pricier, but is ready to use professionally. The person who sold us this unit said it was working fine, but in reality, it had several significant problems and needed a full and costly overhaul, including a $200 part (and others).
37383x
Here's a list of some of the work we did to this unit:
Cleaned unit inside and out.
Rebuilt power supply (replaced electrolytic capacitors) (future-proofing measure)
Replaced all electrolytic capacitors throughout unit (future-proofing measure)
Recalibrated. All ok.
Cleaned all potentiometers.
Cleaned all switches.
Cleaned all key contacts.
If you have one of these you’d like properly restored, we can help!"

Blue Roland SH-101 Monophonic Synthesizer
Note: links to listings are affiliate links for which the site may be compensated.
via this Reverb listing
"Roland SH-101 (1982-1986), 1-VCO monophonic synthesizer with sequencer.
Compact yet just perfectly sized, plastic but sturdy, simple yet full of useful features. Not only one of Roland company's best looking designs, it is also a rare foray for Roland into 3rd party ICs - Curtis Electromusic's CEM3340 VCO chip granted SH-101 its distinctive rich tone. Needless to say that SH-101 defined the sound of IDM, early house and techno, and still rocks on!
This is a rare blue model that has been carefully serviced inside and out, which included replacing all of the electrolytics, cleaning all of the potentiometers, replacing some unstable sliders, as well as performing general cleaning. All the functions have been tested and re-tested.
The cosmetic condition could have been described as excellent if not for some of the plastic screw posts _inside_ the case. Those are notoriously brittle, but have been restored to the best of our abilities."

Get *more* from your semi-modular synths with this gear

Semi-modular synths are great, and even with a sizable eurorack set-up I find myself gravitating to these complete, self-contained instruments more and more, to get the enjoyment of patching without the option paralysis that a full modular synth sometimes inspires.
Nevertheless the big benefit that a full modular set-up gives you is that expandability and flexibility to build out what your setup is capable of by adding or swapping out modules.
But semi-modular lovers need not feel left out! There are numerous bits of kit out there which can help you get more from your semi-modular synths, expanding their capabilities and sonic palettes.
