AMT Legend serie 2

[alltrax74]

Any one interested in drawing big high gain vero layouts ?
These AMT pedals really do sound great.

Here is the topic on FSB : http://www.freestompboxes.org/viewtopic.php?f=7&t=26365&hilit=amt+legend
And the layouts :
- Full layout including clean channel, cab sim & drive out, high gain (generic) and power section

- High gain sections for E2, K2, S2, B2 & D2

Awesome dude

hi mate.
i've read the discussion in fsb, and i can't find the components values for high gain section. on the schem they are like R17P and C25P. any ideas?
i'm talking about this

maybe i'm missing something, but i can't start drawing with no values.

any input would be great

my bad...i thought those where still on discussion and not verified...i'll give it a try asap...

[Alex]

I don't know if the project is verified.
I think the whole thing is still on discussion.

You have the values for each pedal on the last link in my first post.

By the way I built the B1 from Johnk's layout on the main section, it sounds huuuuge

hi guys!
that's my take on the "part one" of this pedal...
it didn't turn out as beautiful as i wanted...but...

i'll try to draw the high gain sections in the next 2-3 days.

also, in the schem, there is a link from the base of bc847 to the cabsim out jack, that i don't show in the layout.

Looks very tight, nice layout thanks !

So drive out tip connects to switch 1B1 right ?
It might also be usefull to add a column to connect the high gain section input at the C5B/R13P/R14P connection

That's a big and crowded board. Kudos for pulling it off.

General remark, I wouldn't mind having a vero for the AMT cabsim only, as I find both a good one and a useful one. Hi-gain dirtbox layouts a plenty but good cabsims on the other hand are rare.

I'm not sure i understand how the off board wiring will work?Is there any chance of making a diagram?

[motterpaul]

Just FYI - The AMT B1 is in the blog section and it IS a great drive. It is one of my pedalboard pedals. Very high gain and versatile in EQ. These are great and I look forward to seeing more.

I personally would like to see just the pedal gain sections - I don't need cab sims, etc. That is just me, though.

[alltrax74]

I also built the B1 (not boxed yet)
I agree it's a great high gain distortion which stays very tight but a bit too trebly for my taste I play it with the treble pot fully closed
Does the same go for you ?

[motterpaul]

Indeed, I barely even crack the treble pot on. Even the midrange is a bit biting but the pedal sounds very good if you dial the midrange down and then dial in the treble to just the right amount.

By the way - the Brunetti Mercury (in the contributions section) sounds like a slightly lower gain version of this pedal; meaning that it has the same tone and quality, but less gain, so it makes for a nice rhythm pedal when using the B1 for lead.

I actually added an effects loop into my B1 so I can plug in my delay pedal and get repeats when I switch it on for leads.

[alltrax74]

I removed the high pass filter on treble 2 (10n cap + 56k res to ground) and it fattened a bit the sound, for what it's worth

I had the oportunity to purchase an AMT R2 for a good price, it's definitely a keeper, sounds huge, pretty close to the B1 from this site with a more versatile tone stack. I only tried the drive output

[motterpaul]

You must be using a different layout for the B1 (I know John K contributed one) because I don't have a treble 2 control. I did change the caps for treble from 510p to 680p (made it lower, from 3k to about 2k) and I changed the mid-cap from 43n to 15n (which brought it up to about 1k, previously it was about 300 Hz)

This makes it a completely different pedal. The original layout (here) makes the bass control really heavy (center freq is about 7hz) so if you turn up the bass alone it just adds a wall of low end, then if you added mid all it did was make it thicker. I thought the low mid was redundant, so I raised it.

The bass is still the same and really changes the character of the sound, However, I would like to get more gain out of the mids now at the new frequency.

[alltrax74]

Right I used johnk's layout (the 2 components I removed are on the daughter board of the main page layout)
