This Prophet 600 was brought in for a Gligli P600FW upgrade, which is a CPU/firmware upgrade using a Teensy ++ microcontroller board. It offers improved resolution for all parameters (128 values instead of like, 15 or 7!), a new LFO just for vibrato, arpeggiator MIDI sync and more, which you can read about here. The firmware is generously offered for free by the developer and in order to install it, we procure a Teensy 2++ board, do some modification to the Teensy, flash the firmware onto via USB, and install it in the Prophet 600 in place of the original Z80 CPU. We can do this mod for only about $100 including parts. Continue reading “Sequential Circuits Prophet 600 – Gligli Upgrade”
Should I be embarassed to admit I had never heard of the Multimoog until this one showed up on our doorstep? The Multimoog was a Moog monosynth made between 1978 and 1981 and I’m not sure I understand how it was intended to fit into the Moog product line, or what is “multi” about it. Continue reading “Moog Multimoog”
One of my main pieces of advice to anyone learning to fix vintage synths is to never underestimate the likelihood that whatever problem your synth has is just because of cold solder joints. Continue reading “Juno 60 (#4)”
This is a really good one. SIEL was an Italian company that always quite clearly had their own way of doing things. It is a 6-voice DCO polysynth with the ability to make just beautiful, delicate, lush tones. The square wave can go so low that it just sounds like a lawn mower in the distance. That’s not a very useful feature, but for some reason it always delights me when I encounter it. Continue reading “SIEL DK-600”
Here’s another article I wrote for Reverb.com, devised as a sort of year-end-list for 2017, profiling my favorite vintage polysynths I’ve worked on that can still be had for under $1000. This one’s for all of you who feel like you can’t afford to own a cool vintage synth. Some of these can be found for as little as $300!
I did the Kiwi 8P upgrade on this Roland JX-8P this week and just by coincidence did a Kiwi 106 just last week as well. These are very deep and powerful synth upgrades designed by a New Zealand-based company called Kiwitechnics, and they have similar ones available for a few other 80s polysynths. Continue reading ““Kiwi-8P” Roland JX-8P Upgrade (and a Kiwi 106)”
We had a week full of Junos (Junoes?), with three Juno 60s and four Juno 106es here all at once. These are the ones I did last week in between grinding away at various aspects of an insane Minimoog Model D restoration I’m working on and building a new power supply for a Rhodes Chroma.
This is a pretty much shockingly underrated and powerful synth. I can’t believe you can get one of these for $600 in a world where a Juno 106 costs twice as much. Continue reading “Akai AX-60”

I bought this busted Juno from a guy who was a mover who got it as a tip on a moving job! It was the dirtiest Juno I’ve ever seen. Continue reading “Roland Juno 106 #10 (extreme makeover, synth edition)”
This RS-09 died in a basement flood and has rusty bubbles all over its panel. It has a helpful piece of masking tape labeling the notes on the keyboard with their note names. We were tasked with fixing it basically for as little money as possible, but the only thing we could have done but didn’t do was make it look nicer. Continue reading “Roland RS-09”
