The Fender Super Bassman 300 thread

Is it normal for these to have a low volume buzz? It's the first thing I noticed when I turned it on. I thought maybe it's the sound of the fan, but it's pretty annoying. I searched and found one other post asking the same thing but that person had other issues. My SB seems to work great except for the constant buzz with or w/o a bass plugged in. I tried a different power cable but no luck. It's not very loud nor does it increase if the volume is turned up but it's far from dead silent.

Not an issue I have ever noticed with mine. Could be an earth issue in your house - have you tried it in a different house/venue?

Haven't had the chance yet, but I will be taking it to a venue tomorrow night. I am in a older style home that is raised off the ground. I haven't had a similar problem with any of my solid or hybrid amps due to that, but this is a very different animal so to speak. Thanks for the reply.

I have actually noticed the same thing with my SB, I get a soft buzz as you described. I've noticed the buzz at multiple locations including my house. My v4b is silent at my house and anywhere else...so I'm starting to wonder if I have an issue with the SB?
 
Is it coming through the speakers, or coming out of the head case itself? If the latter, it is perfectly normal to hear the fan wind up to speed and make a bit of noise while the amp is turned on - there's 300w worth of tubes running at several hundred degrees steady state. You shouldn't hear it coming through your cabinetry though.

I just clicked mine on for science and the fan is noticeable, but the cabs are dead silent.
 
Question for you fender pro neo cab users...

Past couple gigs it seems I struggled getting a good thick sound/tone from my SB and 2x 410 pro neo cabs, it's seemed thin and lack any low mid punch. When I turn the bass up or pull the deep switch it seems to get boomy rather than deep thick bass I'm used to with an ampeg as reference. I'm not sure if it the combination of SB and cabs or if its just the 410 neo cabs causing this thin sound? I'm putting the neo cabs up for sale :( and looking for an ampeg 810 most likely as I've never had this issues with big heavy cabs. It's a bummer as they are easy move and sound great at low volume but when pushed it seems to just not sit well for me in the mix. Has anyone else experience this with their neo pro cabs or neo cabs in general?

Are you saying you used to get good thick bass with these cabs, but now you don't or your never have since you've had them?

I have Neo 410 and 610, and this has never been an issue for me with the SB300 or any other head with these cabs
 
Just took some pix just for the hell of it, spring storm in the Rockies! I need to talk to someone about the missing screw for the power plug, I hear it rattling around.

I've just one Neo 410 but haven't had any issues at all with my SB300 except when I plugged it into the EXT output but that's user error

In general...I'm comparing it against my Ampeg 610 cab and v4b and it to my ears seems to be a thinner sound when A/B them...I'm guessing it's more the cab then the head, I'm finding out cabs really color tone more than I thought.
