I'm not sure which forum this really belongs in, so I'll post it in Amps & Pickups and leave a direct in Setup in case our dueling luthiers would like to respond. I had a lesson yesterday with my teacher (an orchestra player) on the subject of thumb position. I was having trouble getting a sound up high with my thumb, so he asked if he could lower my strings to where he kept his (he's arco only, I'm pizz only). He changed the string height from slightly over 5mm(G) and 9mm (E) to dead on 4mm (G) and 7mm (E). The bass immediately became easier to play because of the relaxed tension, and to my great surprise, also had more sustain. I didn't notice any significant change in volume. Later that day I played a gig in a loud room with the bass (it's a gig I play every week). I noticed that my amplified sound didn't cut nearly as much as before, and I couldn't hear the attack nearly as much. My questions: * Has anybody else noticed anything similar after adjusting your string height? (There were some anomalies on the setup at the gig, so I can't be absolutely sure that it was an accurate test) * I'm using a K&K Double Bass Max (similar to an Underwood in that it fits in the bridge wings) and a Trinity mic. My thought before last night was that if anything would be affected, it would be the mic sound, but the adjustment seemed to affect the wing pickups more than the mic. If this is true, what is the cause of this? It doesn't make sense to my wee little mind. * What is considered a "Normal" string height range for jazz pizz? I loved the sound I was getting using Red Spiros on a carved bass with the pickups above, but I am also digging the added fluidity and sustain of the lower action as well. Is this one of those Catch-22 type of situations? * Last, what (if anything) can I do on the Pickup/Amp/EQ end of things to get some of that punch back without jacking the strings all the way back up? It's nice to be able to play in Thumb Position without severe pain. Sorry for the length of this...inquiring minds and all.
