Median compressor

As I often say, I don't have previous experience with any of the associated pedals or the 1176 itself. I'm also not a big user of compression. I have a thumbsucker set at a light comp mostly utilized as a boost for my upright bass in my instrument switcher. I've built and don't use many compressors so I almost skipped this one. Then I saw @music6000 mention that they intended to sub lm833 and curiosity struck me. I figured I could easily upgrade the opamps if this cheaper and easier alternative didn't work out.

I'm pretty sure I'll be keeping it as is. Dialing the trimmer was quick and easy and it sounds excellent. I really like how subtle you can get with the blend. I tried the suggested settings I found on the wampler website with my guitar and it helped get a good feel for the range of this pedal before exploring my own sounds on bass. This is probably my new no.1 favorite comp for both guitar and bass.

The box is a lovemyswitches.com grimace purple powder drop. My only complaint about my experience building this is that I now want an origin fx cali76 for comparison. Sometimes indulging ones G.A.S. can trigger more intense G.A.S.

I may have been a bit facetious, but to take it at face value I think the ol’ MCD only sold those for a little bit, so you could put it whatever you want.

But back to the median, I actually procured the OPA1678s, which I plan on mounting to soic-8 DIP8 adapter boards.
 
While we're at it. What's everyone's experience with soldering SMD ICs to adapter boards? I'm comfortable soldering SMD transistors with a regular iron but not sure if op amps are more fragile and susceptible to heat damage.

I’ve only done a little bit, but I take my time and am a lot more cautious. Just like a transistor, I put a bit of solder on the corner pad, then line it up and get it attached. Then I attach the opposite diagonal corner. If I’m doing multiple ICs, I start going round robin to give each IC a chance to dissipate some heat. Otherwise, I do a couple legs on opposing sides and wait.
 
Great finish and nice build!

I noticed you used adapters for the FETs. Was that to ease the process of auditioning / matching the FETS or did your SMD FETs not match the footprint already on the PCB?

Auditioning, yes. You can tell these came from separate batches since they're attached differently. The Left one got resistor leads while the one to the right is a much more rigid pin strip from the opposite side so I couldn't bend it out of the way.

I went with NOS T092 types for the same reason. The first SMDs I soldered directly, would not bias.
