Just arrived here a Genz Streamliner 900.
I'm pairing it with Fender P bass into a Bergantino HS210. So far, so good.
I think I need to quite understand the gain structure yet, though.
As far as I experienced, Gain, Volume and Master pots provide a linear (to the ear) increment of the output from 0 to 10. That's nice, allows for an easier fine tuning.
At first I set everything at 12 o'clock and the output seemed low-ish to me. I tried to increase the Master first and the volume increased but nothing dramatic really. Set it to 12 o'clock again, increased the volume and gain instead: there's a huge boost in output in the 12 o'clock - 3 o'clock range. Can't remember if the Gain button was pushed.
Another thing I noticed is that I couldn't get the head into overdrive territory at bedroom levels (aka very quiet levels): do the master and volume need to be pushed a little bit as well to obtain an OD or is there something wrong?
And last, I experimented a bit with the DI out into my M-Audio fast track sound card and with the headphone out. Very good tone.
Still, compared to my old GK 700RB II, the pre-eq DI out had a much lower output (used to crank the DI out level with the GK though). With the post-eq I can attain hotter signals by cranking the volume and gain a bit
Same with the headphone out: I'm getting a VERY good and hot sound by setting gain, volume and master at 12 o'clock with the gain button PUSHED. If the button is off, it starts to be a bit quiet.
I'm not really sure if those are problems at all or if I just need to get a hold of this new head with a completely different gain structure.
Otherwise, the sound blew me away so far.
