Interesting you mention this. In my link below, the "Jamie's Cryin" clip is a plexi circuit with the 2203/4 front end. The only other change with the 2203/4 is .1 PI Couplers instead of .022. Needed more fullness with the JCM type pre section.
The Little Dreamer clip however, is Variac'd plexi, everything dimed, (except VOL I which is only on 6 and VOL II on 4) straight in from a DSD and into a load box. Then re-amp'd to the power section of another plexi for volume control. Which is better is of course a matter of opinion but the Jamie's Cryin (MV type) sounds just as good to my ears.
Your first clip in this thread is the best sounding IMO. Always enjoy your playing too.

I'm not sure. I need a little lesson on how to connect that filter. It's always so diificult to mess with that one - i always end up having to lift the board b/c the wires aren't long enough to pull it through the chassis and see what's going on. The stock version of the plexi has that filter hooked up to both sides of the cap? - or just one?

help me out. Talk to me like i'm stupid - because i am!

Sorry mate, you're asking the wrong guy. I'm just starting out with all this stuff and don't even have a fully completed build under my belt yet. Right now I'm in the process of gathering the right parts and trying to learn as much as possible. I've learned a ton in the short time I've been here, reading what all of you obsessive tone-chasers have done and are doing has given me some insight.
Great chops BTW! I can't seem to remember the details of your recording chain. What microphone(s) are you using? What's it going into? Lastly, what kind of speakers are you running? Oh and sorry, what pickup?

The preamp cap has two halves. One side serves v1 and the other side serves v2. The two sides are de-coupled by a larger 10k resistor on the board. You never want to jumper the two halves of the cap, or you would defeat the decoupling resistor, and have both v1 and v2 being filtered by the same cap.
Sounds like Rob's SL has a top mounted can cap, while the 12xxx has the cap(s) mounted on the board.

correct - and thanks for the clarity on the way the pre amp cap works.

Here's a NEW CLIP:
http://soundclick.com/share.cfm?id=11683598" onclick="window.open(this.href);return false;
This has the 330 on v2a. And mxr 6 band inline after the EP-PRE but with just the absolute slightest bump at 800 and 1.6K. Almost invisible to the naked eye.
It seems that just having the 6 band in the chain adds a compressive smack to the lead tones.
I'm really happy with what the 330 adds to this amp - I've never liked it before, too mushy - but this amp can take it - and it seems to add a rubber quality to the attack that i hear in ed's tone. Still no tennis racket tension but an added elasticity to the lead tone attack. Still looking for a little more hair on the lead tones - there are a little too bell like - BUT the mxr is adding a smack - when you hit a lead note hard you can feel it hit its head on the tone ceiling - which gives a fullness and sustain.
To me... this is the best tone yet out of this amp. Curious if you all agree...
This is a great tone... this thread is epic, and have been following with great interest...
With this particular tone, do you have the details of what you have component wise? Or a schematic?
I have a 50W 1987 I built years ago, but am struggling to try and get a decent cranked tone out of it. Would love to see if your applied changes would make a difference in my case.
Cheers!
