How does the PV 6505 tonally differ from 6534?

Re: How does the PV 6505 tonally differ from 6534?

May i please (huge please) add . . . how does the above two amps compare to the original block letter 5150 ?
 
Re: How does the PV 6505 tonally differ from 6534?

The circuit on the original "blockletter", the "autograph" and the 6505 is exactly the same AFAIK.

The circuit is the same but some of the components and even manufacturer of the transformers have changed. The changes occured during the script logo production run. So if you sit 2 amps side by side they wont sound 100% identical but the differences are very minor. The brand and health of the tubes has a much much much larger effect on the difference between 2 particular amps.

Ahh great - thank you very much !


Looks like there is a Black Letter in my near future.


This will be my 1st high gain amp - let's see how it goes !

6l6 vs el34 tubes in the power section. Just the inherent differences between them. 6l6 are bigger on the bottom, el34 cut more. Won't be a Marshall/fender difference but the el34 is traditionally more British and 6l6 more American. I wouldn't try and make a good comparison without playing both side by side.
 
Re: How does the PV 6505 tonally differ from 6534?

My 6505+ is a midrange machine. I couldn't imagine it with even more mid. I think they should have put el34s in the regular 6505, the plus version is already tight and punchy. The regular version has more bass and el34 tubes would tighten it up and accentuate the mid imho.

Talking about EQ's and what not . . .


. . . is anyone using an EQ in the FX-loop ?


What will happen if i use, say, an MXR 10band in a 5150, and boost the low end spectrum ? (31 & 60Hz)

Will it tighten the amp's low end more, or will it make the low end (((LOOSER))) ?

Thanks guys !

Re: How does the PV 6505 tonally differ from 6534?

Probably flubby if you just boosted the lowest. But if you played with the different bands you could probably tighten up a good bit. I'd recommend a sonic stomp (sonic maximizer) in the loop. I used one for a long time with great results. It has a low and hi focus and does something different than a normal eq. If you're buying a pedal I say give it a shot and see how it works. If you already have an eq to use, play with cutting the lowest and slight boosting some of the other frequencies.

EQing in the loop is awesome. If u dont have an EQ pedal, def get one. U can really sculpt your gain. I run a 10 band in my loop and it stays on all the time.

As for boosting certain bass or low mid freq, i personally feel it can get boomy and too much will turn muddy. This is also completely dependent on if u boost mids, high mids and treble. And your pickups
And speakers. And...
 
Re: How does the PV 6505 tonally differ from 6534?

Thanx for the EQ-info guys !

Yes, i do have a 10 Band, but never had an amp with an FX-loop.

Once i get that block letter, it will be my 1st :D

EQ in front: Here, you are essentially processing your guitar signal. Adding lows here typically results in a flubby low end IMO....especially with high gain. I used to use an EQ like this for a clean boost with a little midrange added to hit the pre-amp harder for leads.
EQ in loop: This is where you can REALLY sculpt your tone because now you are processing the pre-amp signal. This is how the built-in graphic EQ works on my VHT Pittbull and the tone shaping possibilities are endless. It won't really make an amp tighter per say; that has more to do with the actual amp itself. Those old 5150's are pretty tight anyway.

As for the 6505 vs 6534....I really don't dig the 6534. I found it too bright and even a little shrill. The 6505 was originally designed around the 6l6 tube and I think that is where it sounds best. I found the same thing with Mesa rectifiers....they sound better with 6l6's. That is my humble opinion of course!

Overdrive in the front, EQ in the loop, if you can't find your tone, then you need to put down the guitar. :D

I had an original 5150, still kinda wish I hadn't sold it.

+1!! Definitely use a Sonic Stomp. I use both a Sonic Stomp and a parametric EQ in the loop. Ultimate tonal control!! The Sonic Maximizer sounds as if you took a "blanket" off of the speaker cab. It is a super useful tone sculpting tool.
 
Re: How does the PV 6505 tonally differ from 6534?

I have yet to find a 6534+ to plug into and listen.
I have a 6505+ and I like it, but I can see it sounding cool with some of that edge and snotty upper mids that EL34's typically impart. But that's why I'd like to plug into a 6534+, to see if that's so. If it sounds shrill, I guess it's a cool idea that doesn't work out so great in practice. Thanks for the comments from guys who've played a 6534+. Others out here are curious.

So what does a sonic maximizer really do ?

Is it an EQ pedal with round knobs ?
