installed a SCSI expansion board and SCSI2SD drive in my MPC60 tonight
took me a minute to get everything communicating but wasn't too bad
woooooooo saving and loading is way faster than the floppy emulator that i have in there also.

Nice! My limited experience with scsi tells me that anything you can do to avoid it is worth it. :lol:

lol yea i had no experience w/ SCSI
but the 60 is so old and the floppy is so slow that the SCSI is like actually really worthwhile

used to take like 60 seconds or so to load up 400KB(!) worth of sounds. yes KILOBYTES
now same set of sounds load up in like 5-10 seconds.

They are sallen-key active filters. I'll post the schem and vero layout of the filter/boost when I get back to home.

Repeat Percussion and modified si Fuzz Face. Fuzz engages on the push/pull bias pot. Some ticking comes through when it's fuzz only and the RP gets unstable when the rate pot nears maximum on either speed setting. Ticking goes away if you turn the rate down.

Thanks, it could be better - a bit of veroboard hot glued to whatever was nearby, not what I like to see in a pedal myself, but it works.

Next build will be a yellow jacket OC44 Rangemaster on tagstrip. Working on the graphic today.

"Yellow Jacket" finished...

Stoked on the image transfer. I followed a tutorial on Youtube for transferring laserprint to metal using regular copy paper and polyurethane varnish - takes a while to do but works super well. I'll be doing my next few pedals this way.

Huge 0.005 input cap cos it's the only 0.005 I had and I was determined to keep it original values. Took some juggling to get it all to fit in the enclosure with that huge old Allen and Bradley pot that came out of a valve oscilloscope. I was lucky the battery just fits. Would have taken a quarter of the time to build if I'd used a PCB and small components but starting with the 60s yellow jacket OC44 this became a romantic enterprise.

Props to Tom, I did a clone of his Phantom Octave (with a Parasit Studio relay bypass board). Not the cleanest build inside, but works and sounds good, a responsive and versatile octave fuzz.

Pre-painted enclosure (graphics tbd), Lego LED lens, side volume knob.
