using a 25k pot instead of 1k. any issues

[brendandoher]

the drop in dayton board amp I'm using has a 1K pot for volume. The existing garbage solid state console has a 25k pot installed. what, if any issues would arise from the 1k expected range of volume being controlled by a 25k pot? usable volume range limited to the first 1/25th of the knob turns?

Is the 1K pot bad?

You will only get decent volume with the control up near full. Plus, there may be a capacitor driving it, which would change the low freq. rolloff by quite a lot. You will lose a ton of Bass. You'd be safer to use a 50 k pot if you can't find a 25k. Try Angela Instruments, they have a nice supply of NOS Clarostats.

Depends on the circuit configuration. If used as a genuine potentiometer (rather than a variable resistor), the output from the tap will be the same, regardless of the resistance. However, as triode17 suggests, if there's a capacitance involved in the circuit, the increased resistance may affect the frequency response.

So, really, it all depends on the circuit configuration.
