Ibanez Tube King TK999US. Use a low gain tube and keep the gain control low. Crank the output level, bass just below noon for a slight low cut, and mids to taste.

Kinda like a boost with a little color, but not completely clean. This version of the tube king is basically a Butler Tube Driver with 3-way active EQ, external power supply, and is properly buffered.

I like the Boss SD-1 too.

I play modern hard rock tuned to drop C and I am looking to try something other than my Fortin Grind.

I'm a big fan of the more mid focused, chewy stuff.

Any of the Friedman boosts do the trick?
Soul Food/Klon perhaps?

Thanks.

BONUS POINTS IF THE BOOST HAS AN EXTERNAL RELAY FOR SWITCHING AMP CHANNELS AT THE SAME TIME THE BOOST IS ENGAEGD/DISENGAGT

The Friedman Buxom Boost.

The Maxon OD820 Works great Too. My all Time Favorite Truthfully is the T.C. Electronic Booster/Distortion from the 80's

I recently shot out SD-1, Tube Screamer, Klone, Green Rhino, Timmy and Gain Changer in front of a JCM800.
Klone is what made it to the pedalboard. Timmy, Green Rhino and Gain Changer all had something good to offer and were more versatile than the SD1 or TS. GR was a close second.
