@fafakiwi I think a lot of people forget pickups in the quest for Gilmour-like tones. It's important to note the bridge pickup for Sorrow.
The way I approach it is to have a clean Hiwatt with good cabs...right now I'm mixing a hiwatt cab with an SM57 on the left with a Marshall with a R121 on the right or it could be both on each side, I can't remember.
Signal chain is usually something like the following:
- Opto comp
- Maybe a boost (Tube Driver or FET Boost will do - I prefer putting a bit of gain on a Tube Driver) (and can go before or after your Muff)
- Muff with a fairly high gain
- CE-2 (can go before the amp (my preference) or after the cabs. You may also want to do the Gilmour thing and turn the mix down, OR you could pan it to the left, with no chorus on the right, which makes some nice textures)
- Amp and Cabs
- Digital delay 400-500ms (guess) with roughly around 20% mix
- Optional rotary (I don't like it though)
All of the above are guesses without looking at my preset, but it should get you an approximation. I'll check later, when I get home to see how accurate it is!
Needless to say, Sorrow is one of the more obtainable tones that you definitely can get as far as Gilmour is concerned.
Also, you'll find the feedback is easier to get with loud volumes. And don't be afraid (sacrilege) to use humbuckers!
