Alright, I got a question.

Balanced 12AX7 for the Phase Inverter. Notable benefit, or stupid myth?

If you're an audiophile it might matter, for guitar amps - not so much.

Stupid myth. One, the PI isn't balanced no matter what you do because of how it works. Two, the two halves of the triode are going to age at different rates. Three, the power tubes themselves will age at different rates.

What is JFET technology and how does it work?

I've heard it used mainly what sounds like as a replacement for diode clipping in the gain stages of boosts/OD/distortions.

I've also heard a couple of people claim its some pretty advanced stuff.

Honestly, it's a lot more complex than can be covered in one post. In short, it's a Junction Field Effect Transistor. They can be used in numerous ways, some sound good, some don't. It's not even remotely complex. Any idiot can design a FET gain stage. Anyone claiming that it's advanced is an idiot, or trying to sell you something.

It's not a replacement for diode clipping. Though one way to use FETs is to use the individual junctions as diodes.

Do graphic EQs affect the amp's EQ section or the amp's output signal whilst in the effects loop?

The loop is after the tone stack so it affects what hits the power amp, not what hits the preamp (ie. the tone stack). In front of the amp, an EQ will affect the dynamics of the preamp distortion, in the loop it is modifying what the preamp has already done.

Depends on the loop and EQ. Some amps have a crappy loop that's just a break after the tone stack, and anything placed in the loop will screw with the amp's frequency response and the range of the tone controls, along with output level if the EQ is run at pedal level (-10dBV). A properly designed effects loop will isolate the amp's tone controls from the loop driver, and you won't see any change in how the tone controls operate. And as long as there's a recovery stage, you shouldn't notice any drop in output, though you may need to twiddle the master or return level control depending on the design.

cool modifying the gain before the power amp infront of the amp sounds like it could be fun

Well, what I mean is the theory behind a FET is pretty complex. Its practical uses and circuit design around them is not. Like pretty much any electronic component. Explaining what a FET is in technical terms and then going into how they work and what the field effect is, and the difference in performance when compared to a BJT wouldn't be terribly useful, as the only way to understand that is to have a reasonable knowledge of electronics under your belt. And that knowledge isn't needed to design pedals or music circuits (usually).

Mesa Boogie 5/50 for $700 Canadian. Is that a good deal just looking for opinions. I've been looking for a Peavey JSX with no luck how does this amp compare?

I play mainly metal but I would something that is well rounded and can play cleans.

The Express 5:50 and 5:25 aren't regarded nearly as highly as most Mesas, though I liked the 5:25 I heard well enough. I don't believe they're a good choice for metal, though. I believe they're considered lower gain than most Mesas. I think a better option might be the F series from Mesa.

I know nothing about Canadian prices, sorry.

As stated in the other thread, $700 is a good deal for that, but you're not going to get a metal tone from that.
A JSX on the other hand will do metal just fine, and it will have cleans decent enough to be played if you're mostly into distorted stuff.

Thoughts on those EHX pedals with 2 preamp tubes?




I had the English Muff for a brief bit and didn't care for it at all. Sold it off immediately. Seemed very gimmicky as well as a clunky bit of kit. Seems there are far better pedals out there but I'm not a pedal guys. I have no experience with the others. Not very helpful I know.

Well if isn't the 5150 III you can get it for cheap, but in that case a 6505+ or a Vypyr tube would be better.

Hey guys, back again

I was wondering if anyone mass produced a 4x12 cabinet with an open back, or with ported sides, etc., just because, depending on the players settings, a 4x12 is a death laser if you step in front of it.

Thanks

mesa boogie made a 1/2 open 1/2 closed 4x12. i think VHT makes a straight open 4x12, so does bogner i think. i think there is a number of 'convertible' ob/cb cabs, the only one i can readily think might do that is avatar (doesn't help canadians)

you can convert any cabinet to open back, just make a new back board for it from baltic ply or mdf.

but if you are having beaming issues and you like most the other aspects of the cab then maybe you should use some beam dispersers.

http://www.webervst.com/blocker.html

they are supposed to disperse high freqs. i have never used them so i can't really speak on how effective they are. i should also mention that i have heard you can get a very similar effect by just placing tape on the grill of the cabinet in front of each speaker
punk isn't dead, it's always smelled that way.

So (Ippon), I'm pretty sure I'm going to buy an Royal Atlantic in a couple days. I was wondering if my cabinet, a Blackstar HTV-212 would be able to handle it. It has an RMS of 160 watts, iirc, so 80 watts per speaker, and the RA is a 100 watt amp. Will these co-operate? What happens if I run two speaker outs of the RA at 8 ohms into the two 16 ohm ins on the 2x12? This is bad, right?

Yes, it'll handle the power. You'll want to run one cable, and match the impedance on the amp and cab.

Yeah, the RA has 8 ohm out, and the HTV-212 has an 8 ohm mono in. Now silly question, if it has an 8 ohm mono in, it is using BOTH speakers right? But only has one signal coming into the cab. I understand, but don't at the same time, haha.

Yes, it is using both speakers, they are probably wired parallel. Remember in school when they talked about series and parallel wiring?

Yes, both speakers will run. You would only use the stereo inputs if you were wanting to run more than one head.

I have a Marshall amp and an Mg412a cab (4x12 celestion speakers) and I've just bought a bass. Does anyone know if these speakers can handle bass frequencies safely? It will only be used in my bedroom so less than 1 on the volume. I'm not asking if it will sound good just if it will be able to handle it.

I have a 7-string in dropped A and a 6-string in dropped B and the amp sounds great to me (the low A on my 7-string is an A1, same as a bass' A string just for refence.).

Thanks guys.
#76
Yeah, they'll be allright.
Though, the MG celestion speakers are a lot of stuff I will not list, and they'll not sound good in any case.

No one's posting questions to answer so I will!

When I switch my amp onto standby after playing the tubes will click a little and sometimes I will hear a little click about 10-15mins later - same sound.

Is this just the tubes contracting after the heat from play? Or should I be worried?
