My 16 year old son plays all three and as I expected has become very excited about his Helix. Currently he runs it through his Blues Cube Artist but I want to take it to the next level. I want to get a speaker that will eliminate the need for carrying heavy Bass Amps around but yet be able to produce great guitar tone. Keep in mind Upright Bass in Jazz Band is his main gig. Any recommendations??? Thanks from a dad that really doesn’t have a clue.
