Aion Electronics Aurora Pedal

[Woltz]

I mentioned in my Aion Gale thread that I'd ordered an Aurora PCB from Aion Electronics at the same time as I got the Gale PCB.

Here is the link for anyone interested: https://aionelectronics.com/project/...na-compressor/

I'll post up some photos when the parts arrive.

Nice, I can't wait to see how it goes.

I haven't built a compressor yet, but it's been on my list for a while. Currently using the digital compression built in to my amp (THR10C) but I am moving more and more towards analog pedals. For quite a while I have been leaning towards an Orange Squeezer type of circuit, either on stripboard or one of the PCBs that are around. But after reading this review on Ovni Labs of the Madbean Afterlife I am thinking of ordering a Madbean 4:1 PCB. It's the Afterlife with an additional blend control for mixing the dry and compressed signals. PCB is just $6 US but like most things the postage and exchange rates will hurt. It's designed for a 1590G enclosure, but that appears to require some parts I don't have like low-profile foot-switches. I would probably just build it into a 125B and try to stick to parts I already have.

Ah yes, exchange rate and postage. Turns a $6 PCB into a $30 PCB. Maybe back to an Orange Squeezer on stripboard

Nice, I built the Madbean 4:1 which utilises an optocoupler.

where are you getting the CA3080 OTA? or are you using an LM13700?

[jugglindan]

How do you find the 4:1? Once I saw how much the PCB was going to cost, I went back to planning a stripboard build of an Orange Squeezer. But then I found that the 2N5457 JFETs are getting quite pricey now (over $10 for 2 or 3). I ended up getting a Julius kit from Pedal Parts Australia for $25. It's a great price. Won't start until I finish my other pedal projects though.

Pedal parts have CA3080s but I ended up ordering a couple from Worldwide Electronics Components in Bayswater in Perth.

All the other components I'm going to order from Pedal Parts to keep it simple by getting it all from the one spot.

Great, thanks Woltz, this will be my next compressor build

I usually order a bunch of PCB's from Madbean for my "pedalfest" for that year. lol
It was shakey start, I muffed the 4:1 build once as I didn't use 9mm aplha pots and tried off board 16mn pots. I really didn't like the size of the enclosure I needed so I got some replacement pots and bingo! works a charm. Look I don;t use a lot of compressor, but it does the job when I need it.

I like Pedal Parts Aust, I did their Boost kit and works great. actually one of the best boost pedals I have.

[jugglindan]

16mm pots are not usually a problem for me since I have a stack of 125B enclosures which have plenty of room inside. I am putting the Julius into a smaller enclosure though.

The boost on my OD-2 is quite nice, but I don't use it much. I prefer to use my Timmy clone at a low gain setting in much the same way. I like the tonal texture more, and it drives my other dirt pedals wonderfully when I want.

I use light compression all the time. It's just always on. I like the way it evens out the attack and makes fingerpicking pop a bit more. Unlike standard wisdom, I run compression after dirt. That way I get a more dynamic response from the dirt pedals.

Ohhh I've wanted to build a Timmy, but haven't got around to it. Did you get a Timmy PCB or etch or vero board?

Have you tried a Red Llama clone? one of my fave OD's
