LM3086 Fuzz Face?

> Should be possible to find another usable transistor array that is still in production.

Pick-n-place robo-assembly and SMD has made single devices cheaper than multis.

DigiKey lists few through-hole arrays, all special and costly.

I'm not sure why you would feel the need to find a "modern alternative" when NOS CA3086's are inexpensive and readily available. Contrary to what has been said, they aren't "tough to find" at all.

You can buy CA3086's for $1 each + shipping ($4.95 + 0.25 each additional - but I'm sure in large quantities you could negotiate flat shipping).

Of course you could just get a surplus parts finder to sell you some - Ralphs shows them for $.47 each. It shows that they have a qty of one, but likely that that is just for the website - you could always call and find out.

ABRA has them at $.89 each ...I'm sure you could get a qty discount.

You can just put in a "bid" for whatever qty you need at USBID.

Or, you could just contact Mammoth - they show them at $2 each with an available qty of 498, but I'm sure you could negotiate a qty discount.

Of course the "old standby", Futurlec, shows them at $.79 each, but has a discount to $.70 in quantities of 25 and $65 each in quantities of 100. For larger order discounts, contact them.

There was one boutique repro of the big muff that used a transistor array chip

to be true, I think that the whole idea isn´t interesting for most fuzz circuits.

If I had to make a larger number of Superfuzz workalikes, the 3086 really would make things easier, because of the matched transistor pair for the octave.
But for a simple Big Muff etc? I can´t see any advantage.
In a Fuzz Face, it´s interesting to play around with different transistor, and the best sounding pedals have transistors with different hfe´s, so maybe a 3086 wouldn´t be a good choice...
