Stoner/Doom Bassists Thread, Part 90: Maxed Out

if youre planning on using this as your gigging bass amp, my vote is NO. It wont be loud enough.

I guess it depends on how loud you want to be. If you don't mind some seriously fuzzed out bass, with a 2x15 or two these things can be pretty brutally loud. The 120w rating can be a bit misleading, as the Sunns were measured using Hi-Fi standards. Thus 120 watts RMS continuous, 20 Hz to 15 KHz, within 1 dB of 120 watts with less than 1% total harmonic distortion. If put out by almost anyone else, they'd probably be rated around 200w.

However, I understand some people here need to be even louder, so YMMV.
 
Gut shots of the Octling for those of you that care. Not as neat as some of Nick's builds IMHO, but it isnt unimpressive.

Here are some gut shots.

Another thing I think is cool, is the shadow that is cast by the light bulb under the cage. This is what it projects on the wall in a dark room.

Well caps are not as ideal as one would think. There are a few different non-ideal characteristics that arise depending upon the type of capacitor. So if you are trying to maintain the ideal output impedance of the cathode follower you have to take those into account. For example if the cap was a large value say 100uF cap (sufficiently rated for the DC voltage on the cathode, 100-300V) then it would likely be an electrolytic capacitor. Electrolytics suffer from something known as ESR (equivalent series resistance). Usually at low frequencies for an electrolytic the ESR is like a few ohms, so in the case of AC coupling from circuit to circuit that means nothing. But at higher frequencies say 1kHz and up for example, the ESR increases. A cap with ESR is modeled as a capacitor with a series resistor so as you can see if you are adding series resistance off the cathode follower circuit, that will increase the output impedance as frequency increases!

Now lets assume instead of a electrolytic they used a 100nF film cap. Film caps suffer very little ESR, they are more ideal in that regards. However if you are trying to drive a load of around 400-600R as calculated by the followers intrinsic impedance, then the 100nF -400-600R RC filter results in lots of filtering of the low end. So effectively at low frequencies the output impedance is very very large in this case.

So one solution people often use for these things is to put a 100nF cap and a large electrolytic in parallel. In this case you can overcome the ESR at larger frequencies using the 100nF cap to shunt across the 100uF cap.

I cant say for sure if this is a problem with your preamp or not until I know the output cap used for the DI and the load that it is being placed under.

Thanks Nick. I will say listening to the clips I recorded, there is no lack of low end. Not sure how much of that is the pre, or my dingwall. I had no trouble running the pre straight in to my Tascam DR-40 and getting good tone, or signal level.

For the price point, I was willing to jump in. Still have to play with the band with it.
 
You got Zimmermaned Bryce!

Moms frustrated, and mad at the neighbor who did it and the police. We have a very inept police force that responds to our neighborhood.

We have a crazy dude whose like 30's-40's and lives with his parents here. One time he ran up at a neighbor who got near his driveway swinging a 2x4 with nails in it. then said I have a gun and got in his truck and pointed to a shotgun in the back window. My neighbor called the police and said there's a guy at this address, in a red truck with a shotgun threatening me.

Hour later the police show up at the not crazy guys house and chew him out for calling them and sending them on a wild goose chase for a man in a "bread truck" :banghead:...
 
Is it too neurotic to not contact a drummer because they're a 20 year old girl? Someone posted an ad on my local CL that comes off super professional (well spoken, no nonsense but friendly, looking for something dedicated and focused, link to some high energy metal drum covers), looking to start or join a metal based band that will be active. I'm a little spooked by the fact that it's a 20 year old girl (her word, I'm fine with "woman" for anyone over 18) with sleeve tattoos who posts youtube videos of her shredding on drums in skull and crossbones patterned sports bras. Am I being a weird d*ck or should I just respond to her ad and she if she's into the music I write? It is really hard to find dedicated people here that aren't total flakes. I have zero problem being in bands with women (I'm happily married and never had any weirdness about female friends when I was younger), I just don't have any social interactions with 20 year olds and I'm not sure if me being on the ripe end of 35 automatically makes me a creeper if I do.

Im gonna need to see those you tube videos before I can make a judgement...

hahaha bread truck. that's some serious barney fife **** right there.

Also we only have a volunteer fire department, and every year they put Santa in the bucket of the ladder truck and let him throw candy to kids. Well a couple years ago they drove Santa into a tree and broke his nose and fractured his cheekbone, so all the kids are running outside to see Santa whose slumped over the bucket with a bloody beard screaming for the driver to stop.to no avail.

Years ago I got a reply to an ad from a woman that plays drums. Curious about her abilities I googled her name to see if she'd been in any bands in the past, high up in the results were topless photos of her - artsy ones - but still. I was in a long and committed relationship at the time, I didn't want to try to explain that one to the GF so I didn't respond.

Anyway - I agree w/ Ampegfuzz. I have class with 18-20 year olds, some of them are cool, others are not. I wouldn't want to be in a band with any of them.
