I'm looking for the opposite direction
I'm running a mxr custom audio boost/overdrive
its overdrive section is a lot more transparent than screamers and the sd-1, and doesn't boost no near as much mids or cut that amount of bass
just a big and aggressive crunch tone with not much tone shaping, instead of the thin, smooth and midrangy sound of a ts9
I used to be a tube screamer hater, but now I'm looking for the soft and slim thing (my main les paul is very bass heavy, though)
the CAE is a lot clearer and thicker sounding, but doesn't deliver the juice I'm looking for
I've been experimenting with my 1980 maxon 6 band equalizer as a booster, but it reacts very different from a tube screamer, although it has the same classic JRC4558D opamp
it has a lot more output and noise than a ts9
by cutting bass and adding mids, I get a very aggressive crunchy sound, like early Tool or something
I'm using mostly a '73 les paul custom with BK cold sweats though a modded hi gain 1972 50w Marshall JMP rebuilt by some mysterious tech (not homemade) from california... tone reminds me of early Soundgarden and Corrosion of Conformity, and also a custom Zambelli Hyperdrive 50 (tonewise it's somewhere between a Bogner XTC and a Diezel or something), sometimes a stock Laney VH100r (I always roll off treble, presence and bass down to zero and dime the mids on that particular amp)
I like the CAE with the Zambelli, but the Marshall sounds much better with the TS9
