Amazing piece of electronic!!!

I get the unipre as an upgrade for a harley benton bass.
I read the specs of some preamps and i ended up choosing it because of the shaping options and the quality and i did a great choice, this pre is amazing it upgraded the sound of my bass far above its price class . The tone, the playability, the sustain,everything that was lacking is now there, and the pasive sound is so natural, ad to this the shaping options, and ofcourse it fitted perfect. Also id like to thank Max for answering my questions about the pre. i like the fact that here in FBT they know very well what they are selling

The East pre is very easy to set up and sounds fantastic. Be aware that the bushings on the stacked pots need 10mm holes. My Lakland had 8.5mm holes. A little time with a few round files and everybody is happy.
