Here’s something I don’t post much on my feed. A synth! The great Yamaha TX7 all the ways off having a DX7 without loosing space in your studio or a vertebrae.

Came in with all the patches playing really quietly - weird! Tested all the output first to see if the VCA and everything was working, it was. Traced it down to this pesky little DAC!

I like the DX7 so much I even have a t-shirt of it. (Got the shirt cos I can’t play keys. See vid attached) Whatta nerd 🤘

Grampian 666 I recently worked on for . Fully restored and back to making a lovely sounding verb.

The 666 is the little scamp child of the 636. They can’t really be compared as the 666 has a different circuit altogether. However is still fully germanium. Crazy how different Grampian went with this saying the 636 was built using stripboard. Look PCBs and headers mental 🤘

Ayup Duck! Waddle it be? A big ol serving of a quacking great Mu-tron III. Not the first on my feed not the last. They’re brilliant and do the auto wah (quack) sound the best. Not just for bassists but for everyone to get down their back, sack and quack 🤘

Writing this is making me think about beer. Mmmm 😋

Nice bit of PCB riveting done on a Binson restoration. The old solder tags go really brittle especially if the Binson rot sets in. Re-doing them makes the re-wire easier. May as well do em if you’re inside anyways 🤘

Here’s a cool one you don’t see everyday. A Rebis Audio RA-401. Pretty cool parametric EQ for the legend .

Power supply was blown when it arrived so sorted that then some standard re-capping to go along with it. Really nice EQ! You can get pretty surgical if you like or just go mental and crank it.

Lovely Grampian 636 restoration I did for recently. I had the pleasure of fixing it up for one of my favourite artists as well, little clue in the riff I’m playing 😉

I’ve restored quite a few Grampian 636s now and built even more. Nice to see an original though!
