will removing one battery from my 18v setup give me a more compressed sound?
No. Definitely not.
By removing one battery you will (depending on exactly how the thing is wired), you will unbalance the supplies to the circuit board to such an extent that it simply won't work anymore.
Again, it depends on the actual circuit design, but operational amplifiers like a balanced power / battery supply that has a + component and a - component together with a OV point [which is the connection point between one terminal of each battery, and which is then taken to the circuit board as the ground connection].
You'd be very unlikely to damage the on-board chips by removing one battery, BTW.
Hope that helps.
It will decrease your headroom level.
Rockin John: The EMG´s are designed to work at 9v and up to 27v.
The circuit does not use a DC Coupling +9 -9 but instead puts the 9 Volt batteries in series.
OK. Thanks Luis. I stand corrected. Sorry if I misled anyone.
From Luis' comments it sounds as though dropping from 18 to 9 is quite possible.
If they are in series, then simply removing one will open the circuit and it won't work at all. Unless the battery box has an auto-switch so that when the battery is not in it is shorted, but this is highly unlikely.
Removing the second battery harness altogether should do the trick. In that case, the wire that went from the first battery to the second one should be sent to wherever the wire from the second one went. Hope that made sense.
Edit: But, why bother? Any difference will be small. Use something outboard to work on compressing the sound. SansAmp or something. dbx compressor.
