All this guts talk.....here is what a Quality Amp's guts should look like damnit!

There are lots of two channel PTP (although one should have a more relaxed definition of PTP then) available.

And from my limited experience 2 channels, or 2 real channels and some add-ons, is a technological border. And the reason you won't be able to find a 3 channel PTP midi amp with add-ons PTP.

And it would cost an arm and a leg . . .

Yeah, it's just a matter of having enough ROOM for all that stuff in the chassis if it's PTP at that point.

From what I recall, Jeff's amp has two completely separate preamps.

Yeah, some of them look real purdy. I will take a nice thick well designed PCB board over PTP wiring anyday. I cannot tell you the countless hours I used to spend at work finding wires that were almost or broken inside the insulation, cold solder joints done poorly, and cracked solder joints. When this stuff happens heat often builds up or an arch happens and it takes out other parts with it. You are not looking at the inside of an amp when you are playing it and the {censored}ing tone is in most peoples head, all things being equal.


If you took the same PTP wired amp and put the same components on a well designed board you could not hear the difference if you tried. Wire does not make an amp sound better folks.


Disagree if you want, but my past history of medical equipment repair tells me different. We are talking life saving equipment here. I will take my Bogner, Mesa, and VHT amps over any PTP amp as long as the tone is what I want. If an amp had the tone I was looking for I would over look the PTP wiring and buy it, but I would expect more problems with the PTP amp. It takes just as much R&D, if not more, to design a proper PCB based amp too.


To each his own. Tone and long term durability are the 2 main factors most people look for in an amp. A recent amp here on HCAF had the durability part in question along with lies to customers.


I will admit only time will tell if the board amps will stand up to 40 years of use like many classic PTP amps. 20 years have passed since true quality board amps have been around and they are holding up great. I expect them to last just as long, if not longer than any PTP amp.

If you are trying to say it is easier to debug a PCB, then you are insane.

Just an arm...

A ptp with midi

Here's my PTP-turret SLO-Clone, which I've built for my bandmate - not as perfect looking as Jeffs of course, but it sounds pretty good - the owner loves it - and it looks "better" than a Dumble :D

We even include a footswitch for those who don't use midi (many don't), we have 3 channels and an all tube FX loop.

Can't be done...

YEP! And they are supposed to be replaced every 10 years. The very first thing that you do to a vintage Marshall is replace all the caps ASAP,

What you are referring to would be the electrolytic caps, not the coupling caps or the caps in the EQ section.

and NOT with Orange Drops either!!

I'm not sure where "Orange Drops are bad" concept started but that is not true.

NO, you're right about Fenders, but the Fenders seem to do a lot better as far as caps go compared to high voltage Marshalls especially 60's and early 70's. The 100 Watt 60's and very early 70's still had over 600 volts hitting the plates on the El34's and it put a lot more strain on the caps as a result, thus wearing them out faster, hence they say to replace them every 10 years.

I believe you are confusing coupling caps with filter caps.

Marshall started reducing the plate voltages down to 450 volts sometime around 1973.

Not sure where you heard this from however this is not true either. I say this with having worked on countless older Marshalls. There's currently a '66 JTM 45 in the shop right now along with a 2 67's and neither amp runs over 465V on the plates of the power tubes.

PTP will always be easier to repair out on the road though, and that is saying something if you are constantly on the road and take particular liking to that particular amp.

It really depends on the build quality of each amp and the skill level of each guitar tech.

A lot of very good amps these days don't have that sensitive touch dynamic as do the PTP amps (where when your pick attack is harder the volume incresese but keeping that awesome tone, and when you pick lightly, the volume decreases, but the tone is still full and rich. This is how they get emotions out of their guitars

Touch sensitivity has nothing to do with an amp being PTP or PCB equipped but rather it comes down to how the circuit itself is designed as well as the quality of the transformers.


For what it's worth

Don't bother since there is no difference....

You might as well say that if you fill your muffler with gas, the engine in your car will be more fuel efficient....

:D



But when you rewire the inside of your amp with Monster Cable the sound will be 1000x bettar! :freak:

Far as I know, there are NO PTP channel switchers?



Including the "super fugly amps made by the fidget"? :) How could you forget about my amps Carl? Perhaps you didn't know they were all PTP though, since I haven't posted "gut shots" of them in ages.

Dismissing pedals as a way of getting sounds is plain dumb.



I agree. I bought a Bad Monkey yesterday as a matter of fact, and plan to buy some more pedals. It's not the same as an amp's own sounds but depending on the setup it can be just as good.

I have no preference either way. If it sounds good, it is good.

The argument of using a pedal into a PTP amp is lame.

I'm talking decent pedals, not some $10 Bad Monkey POS

Agreed. Which makes your next point completely wrong.

I'm guessing you've never tried the Bad Monkey.

Get your head out of your ass for once, ok? You are so ignorant it's sickening.
