I was in San Diego this past Summer and visited John Dimaggio at Bass Alone. I wanted to demo some basses and was able to play through the same cabinet that I own; Bergantino HT322. I powered my experience at Bass Alone through a Glock "Soul" head.
John said that it has less power than what I have with my Ashdown ABM500 EVO. But he said the Glock head is one of the most accurate and honest sounding heads on the planet. A great way to hear what a bass 'really' sounds like.
I demoed a variety of basses; Bone Oracle 5, MTD, Celinder, Warrior, Hanewinkel, Sukop etc. (Bone Oracle was truly most impressive)
I plugged in not expecting anything out of the ordinary. But WOW!, was I ever blown away by the quality of tones I heard from the Glock/Bergie combo. The purity and clarity of tone was simply STUNNING. I didn't turn it up that loud since I didn't want to bother the other customers. All that remains is to know whether the Glock Soul Head has the volume and punch for medium to large rooms. I gained incredible respect for Glocks preamps that day.
I would love to know if you guys think the Soul head will keep up with most loud (not stupid loud) rock bands. I also play Funk, R&B, Garden Jazz etc. I'm not so worried about those music styles since there is typically more sonic space in which to live. Thanks!
