sure , i have S/V and Top Boost
super V absolutly Rocks - it is my cleaner tone live . very chimey lot's of usable gain but not as much as the Top boost ---
Super V tone is very clear .. i'd imagine it is close to the VX ... all Lynch mods are outstanding in terms of tone ...
i use the top boost as a medium gain rock mod ... and it's cool sounding
the TB does not clean up as nice as the super v thou ...
but it all depends on what you want those mods for .. i'm not looking for a super clean mod -- that's why the Super V works well for me .. i want a bit break up in my clean tone ... and the Top Boost to me is just a shimme'r version of a Marshall anyway's , as the proper power section and speaker are not there for the true vox tone ..none the less .. TB/ Super V are one of my fave mods
cheers
