Heartbreaker fanatic here. I cant find a decent tone for solos on the Roadster-all the channels sound great for chords, but nothing on this amp inspires me do leads at all. One chorus and I'm done. I got it to get all those great recto sounds, and some good cleans and switch easily between them-but I have lost any kind of lead sound! By contrast, the crunch, and recto vibe is non-existent in my heartbreaker, but the lead tones-good god! Once you find the zone you can't stop soloing-chorus after chorus! I tried the HB speaker cab with the roadster-nope-the same shreaking bs lead sound-not even in the same league as the HB-or am I missing something? Perhaps a Mark IV might bridge the gap-I am at real loss here-any advice?
