Brainstorming for the creative ones....ever wondered about how much makeup gain the GSSL bus compressor has? Thinking: "more than enough"?
If you always thought about having a passive eq and a nice bus compressor...
...try combining pultec filters (or even easier, the "poor man's pultec" ones that don't even need inductors) in front of a GSSL - in one device.
You would get a sort of solid state stereo Pultec with a compressor in a fairly easy build - the SSL makeup gain should be plenty enough to makeup for the loss of the passive filter stages as well....
You have to grab the signals after the de-balancing stages of the GSSL, feed them unbalanced into the passive filters, and bring them back to the GSSL PCB...
In case of the poor man's pultec, you could even realize the filters point-2-point right on the switches. Could be realized in a 2 units high 19" case. No changes to the PSU needed, no additional heat, only one de-balancing and balancing stage per channel, and pretty cost-cutting build. Sure, no tube vibe, but pultec filters are pretty usable stuff without it. Sure - you lose gain before the compressor. So it would be kind of picky with the incoming signal. Might be, you have to drive it's input harder OR set threshold very differently to push it into gain reduction...
But - this could also have a nice side effect...i.e. you may have to balance between eq and gain reduction, which might have MORE EQ and LESS COMPRESSION use as a result more often...not the worst idea, if you ask me...
I am pretty sure, someone already did it...i just remeber, it was a danish member of GDIY...and it just came back to my mind, what a brilliant idea it is after thinking a bit about the concept IMO...
Best regards,
Martin
