Yeah, I can't comment on the Twinface specifically, though folks that have them love them - and I've no reason to doubt any of that. I for one actually liked the stock Blackface. But, every 'clean' modded module really blows it out of the water - no comparison really. TWox, Vybe Deluxe, SuperClean, Texas Special, Loneclean, etc... All awesome modules! IMO, the MTS amps really shine with proper clean modules - after all, if IIRC, the power sections are basically Fender Super Reverbs. I believe it, as I think these are some of the best sounding clean amps ever made, with the right pre's and power tubes. I guess it depends on what your after, but I'll say that the Vybe Deluxe is prolly the best, most all around versatile module there is - of all that I've tried at-least (close second are the various modded XTC's). Awesome cleans, pristine to spank to slight breakup. Start hitting that thing with OD's out front and you can go from deep, complex harmonically rich mid-gain, all the way to Orange/Plexi-ish high gain. Hell, I got rid of my R'Verb because I could get my Vybe to sound nearly identical if hit hard with an OD. Also, somehow, I can feed it ungodly amounts of reverb & delay in front of it, with OD/Dist, and it just sounds perfect, as if it's in the loop - amazing really, kinda defy's logic, lol. Anyhow, I've heard the Twinface is similarly versatile, clean to high gain. So, don't fret, there are plenty of awesome mods you can get on those clean platforms!
