So I'm looking to expand my gig rig. I'm playing metalcore music at the moment. And here's some preamps, that I've came across. 1. http://www.thomann.de/gb/hartke_vxl_bass_attack.htm 2. http://www.thomann.de/gb/source_audio_soundblox_multiwave_pro_dist.htm (I found here on forum, that someone used it like preamp) 3. http://www.thomann.de/gb/bbe_bmax.htm Or maybe there is other alternative for them? I'm from Europe and my limit is 250euros for preamp.
