I've played none of them. But I want a booster that doesn't change the EQ, especially high. Which one is better?

Consider this a bump. I have the SD and love it, but my usage isn't quot;typicalquot;. It is very clean, and doesn't color the sound much at all, unless you want it to by flipping the quot;resonancequot; switch.

Never tried the Fulltone.

Thanks to Artie...I use my Duncan Booster to make my single coils sound like humbuckers to beef up my solo tones...I've not used the Fulltone product,but I'm an avid fan of the SFX-01 thanks to my brother Artie for letting me borrow his! I Keep the gain really low on mine and I use the center resonance position to change the eq of my single coils..I also use the pedal for a slight volume boost..
