AMT B1-S1 Clone

[MetalGuy]

Tell me this sounds like "so far from reality?" This is the D2, E2 and P2 all using the AMT cabsim in each pedal...

This only confirms what I said. Definitely not my cup of tea. Undefined and mushy. If someone is into that kind of sound maybe the cabsim will suit their needs.

As far as cabsims go, you can't really beat convolution. This is one application where digital means have a clear upper hand.
Cabsims can also sound unnatural because of lack of reverb: guitarists rarely monitor a dry, close-miked signal; they listen to speakers a bunch of feet away, in various environments.

Would anyone of you be so kind as to make the PCB layout correctly sized for printing in a PDF file? I'll gladly make a PCB for you as a thank you.

I can't get it to do it for the life of me.

What PCB are you referring to? The cab sim?

Here is the one I made for the cab sim... but I didn't make the parts layout, so if you can figure it out then you're golden   If not I can try to do a parts layout real quick.

BTW: I used J201's, didn't like the sound of the MPF102's. I also tried to bias the J201's to 4.5v on the drain, sounded like crap so I left the 6.8k resistor in there and it measures at around 8.5v sounds good to me! I also used a 10k pot for the treble, 5k just didn't give it enough highs...

Ok, here is what I have.. It's the Bogner B1 with some minor tweeks and cab simulation with bass and treble knobs for the cab sim. Like the AMT it has 2 outputs, one straight preamp out and one preamp cab sim out. If you hit the bypass while you are running out of the cab sim output it just turns off the preamp, the cab sim is still on so you can use it for just a cab sim if you want with other preamps or whatever.... Sounds F'ing incredible to me!!!   In the sound sample I am running out of the P1 into the cab sim in my pedal. Then just the P1 with it's cab sim so you can compare. Then the B1 clone pedal itself with the cab sim. Still waiting on knobs...  I think this sounds better than all of my stuff!!! The ENGL and Diezel are next and I can't wait to get them done!

Top 6 knobs are from left to right (Gain - Bass - Mid -Treb - Pres - Vol) basically like the AMT pedals with the added presence knob. The next row of 2 knobs are for the Cab/Speaker simulation left to right (Lows - Highs)... I know it's a lot of knobs but believe it or not there is still room for a battery inside.. BTW - the cab sim that I built uses two J201's and is NOT a copy of the AMT cab sim circuit!


I just had some teeth pulled so I ain't gonna be playin nothing worth a damn but here are some short samples completely dry no nuthin!

This sample is just so you can compare the AMT internal cab sim with the cab sim that I built.
This is the actual AMT P1 pedal - The first and the last takes are the P1 cab sim out. All knobs set to 12 o'clock in all takes. Completely dry no effects, no nuthin!
All of the takes in between the first and last takes are the P1 running out of the regular non-cab simulated output into my pedal using just the cab sim in my pedal.

Here is the pedal itself, B1 clone using the cab sim and I am fiddlin with cab sim knobs a bit. Again completely dry, no effects nothin...

Do you still have the P1 schematic? and PCB layout of course Thanks in advance

[J0K3RX]

stringline - I do have the P1 schematic... I have not created a board for it yet since I have the actual P1... I will create a board for it, might take a day or so.

If you private message me with your email address I will send you the schematic.

Hows this sound? Too much fizz?

Too much delay. Are you using also modulation effects after it? All these additional processing makes the sound unrecognizable.
Please, try recording it dry.
