I have a laminated Jacques Kohr bass with Obligato strings. Acoustically, it sounds great! It sounds awful amplified. I have a Basswitch and an Fdeck and have tried both in front of a REDDI going direct to a sound system and into a Markbass CM121P combo amp. It sounds awful in both cases. It sounds harsh and thin and if you try to fatten it up you get tons of nasty feedback. Everyone was praising the Fdeck I twiddled the knobs every which way and couldn't seem to get a good sound. I use a Realist with the docking station (with the wooden piezo element). It just doesn't sound good any combination I've tried. I ordered a Bass Max pickup to see if I won't get better results with that. If that doesn't work, I'm beginning to think I have to go with a magnetic pickup which I would prefer not to do. If any one can share some ideas, I am open to suggestions. I'm about to concede that amplifying this upright just might not be possible.
