Thoughts on those EHX pedals with 2 preamp tubes?

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).

Take the old one out and measure it. The dimensions are on the ad. If it's the right size then yeah, switchcraft are solid kit.

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.

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.
