So I've noticed that I need to send my signal coming into the jamblaster, whether it be from a mic or an instrument, through a pre-amp before going into the input of the JB. Ideally the JB would have pre-amps built into it where the user could control the gain, but going to a mixer first and then out of a mixer is a simple enough workaround. However when I start a session with another user I often find I'm STILL having to completely crank my volume to hear either myself and/or whoever I'm in a session with. Either there seems to be a bug with volume control in the software or it's a hardware issue. Are there pre-amps at the inputs of the JB? If so it would be nice to have a knob to control the gain. I'm assuming that when you're telling the JK software what type of input you're using (ie vocal, acoustic guitar, keyboard, etc) it's setting some kind of expected dynamic range and adjusting the volume accordingly but I'm finding I'm always having to crank the volume and still struggling to hear clearly.
