I got my 40 when I had some problems with my 2000 Bassman 25(since cured). After that I got my 100. Nothing against the 40, but between my 100 and my 200c, that's all I need. Unless you really need the 40 for space considerations, just turn the 500 gain down.My master volume has some static only when I turn the knob while a note rings out. If I am not playing, it is silent. Yeah the 500 is not really a practice amp, but you can turn the knob down on your P bass (thats what I do when I'm practicing late at night) or turn your gain down. I plan on getting a Rumble 40 for my late night practices/small gig amp. The 500 is a really loud amp!
FWIW, this is my practice amp as mentioned b4. 200W/2x15. I turn it down.
