What material are these most used for? I know 3a are used for guitars

The biggest difference between LA3A and LA4 (from a user standpoint) is attack and release controls. How is this supposed to work?

“Since both circuits”
Cut and paste from website.
two circuits in one box, so why wouldn’t they have different control settings, but using the two rotaries?

LA3A is discrete transistors, step up transformer and EL-based T4B reduction element. It uses 100K pots for threshold and gain. LA4A is opamp, LED/Vactrol based reduction element. Seems to use 10K pots for threshold and gain. I suppose they could stack the pots, or scale the resistor networks around the LA4A circuit to use just one set of pots. |

I managed to get two of the first run Stam SA3As, and I really love them! This one looks a lot better, the first run had the mod controls on the back...

I’ve got the Stam SA-23A+. The 3A is probably my favorite. 3As in general are probably my desert island compressor. I like both 2As in the SA-23A+ a lot too. I’ve yet to find a home for the 4. I should mess with it more.

3As in general are probably my desert island compressor. Mine too. Stable, always works, sounds great, some character but not overwhelming, sounds "right" on almost everything, never breaks, no tubes to go bad, killer variable attack/release thingie that just works, bonehead simple to use. What's not to like. |

I have and use LA3a and LA4 comp-limiters. The LA4 is much cleaner and 1/2-way to a RevF76
Feast your eyes . . .

It would be nice if I added the attachment. Ratio here set to 12:1 and much like a 76, it's bright here. Ratios include 2 4 8 12 and 20 . No ABI mode.  |

Thx, other that the description on the site, Ther are not in the wild so we know the exact circuits for a while. I think this is the 3rd or 4th multi circuit compressor that Stam has done: 76 adf, adg, sa 2a+ and now this ? |

Oh, shoot, it has been a long time since I had my hands on either. I remembered the dual concentric pots, but forgot it was RATIO control. I just remembered having more things I could control on the LA4. Thanks for the reminder.  The biggest difference between LA3A and LA4 (from a user standpoint) is attack and release controls.

It would be interesting if Josh were to do version with Eddys LA4 mods! My favorite SS opto.

I actually thought of running the LA-4's through the input transformers as well to give it a bit more bite but I thought best to keep them as close as possible to the original design. |
