Yes sir! Helix and tubes are great! Synergy stuff is all tubes. Every module is designed by the the name on the front. Friedman, Engl, Diezel, Fryette, Bogner, Soldano - They all have 2, 12ax7 preamp tubes and the SYN5050 designed by Fryette, has 4, 6L6 power tubes and the SYN2 has at least 1, 12ax7 as well. Helix and just the SYN5050 Power Amp is incredible, combine the rest and it's absolutely a BEAST!
