Simple active treble Boost to compensate for Optical Compressor High end loss..
know of a vero layout? Or Schematic?
Paulinthelab has a Brian May treble booster on vero. Finished it last night, works fine.
I daresay all the usual suspects have one listed. Check Sabrotone, GuitarFX tagboards...
What optical tremolo are you working on? No reason to go with an extra circuit if what you want to be done can be a simple modification.
In general, though, you can use any booster you like, and just use small coupling capacitors. Use a cutoff frequency calculator or socket the coupling caps, and you've got a treble booster.
If you're talking about using a GERMANIUM treble booster, I'd really caution against that. The Rangemaster uses input loading to cut the treble from the guitar signal, and a tiny input capacitor to cut the bass. The result is a really big peak around 1KHz, which quickly falls off on either side. This is good for filling the dip in a Vox's tonal profile (which is at 1Khz -- not for nothing this was a match made in heaven), but it's not so good for maintaining presence in the guitar signal, which is something lost by compression. Putting the booster first in the chain will mean that you might as well lower the input cap in the compressor; putting it after means that you're going to have an EXTREMELY bright effect, because the guitar loading is gone, but you'll still have a massive bass cut, instead of just a simple increase in treble presence.
