Preamps and Effects / Re: Choosing a clean preamp
October 29, 2011, 12:55:11 PM
I was just thinking about the line out of my pedal board. I thought using always the this preamp in the power amp of the amp that I'll get at gigs (usually the places I play in provide amps). If it won't work with most power amps I think I'll just put it in one box with my power amp-this will make things easier but will make my tone to change because of the amp (I have a 5-10watt chipamp which can take the signal straight from my guitar)

Another question. If I put the Phatt preamp before most of my pedal can I connect them straight to any poweramp afterwards or does it have to at the end of the chain so it could go into a poweramp.

I think I'll go with the PhabbTone and maybe will put my poweramp section into a pedal too so it will be a pedal board into a cab. I have a few question about the circuit, first of all what diode to use in D1. Why there is no volume control, how can I add one? Oh and I heard in the demo's that it distorts a little. I got mixed up and I have a 18v instead of 16. Will it distort (btw I have 9v too but I', afraid it just won't work).  Btw is there any layout of this preamp?

Sounds very cool but the problem is that I have to put it before the effects. I'm looking for somthing I can just put in 1 box with the poweramp and simply plug in my pedals or straight from the guitar and it will sound good.

Hay,
I'm looking for a clean preamp-smothing with more fendery sound that will work good with pedals. The problem is that I can work only with 16V. Do you have any ideas of what can I build?

I inserted the C12 and connected it to where it needs to be connected and it's still was 4.6V, how ever then trying to connect the R14/15 node to R11/4/5 node it went down to 1.2V. I think the problem is in this node so I'll take out the wires which I used to recreate the track and try to find another way to recreate the tracks.

Oh finally the R10/14/15 node is 4.6v!!
Now i need start putting things back in place without lowering the voltage. How this can be done (especially with the cap).

Oh, this one. I'll take it out.

of course I have it. But still can phatt point me to the wire he talked about?

Oh, I tried to find now the wire you talked about but I have a hard time. Can you circle where it is in the picture?

It is my first pcb so i f*cked up some things but I the next one should be better (btw in this one the tracks were to thin for home etching). I'll try to do the thing you said today and post what happens.

here are 2 pics but the soldering looks much more dirty then in reality-maybe the flash just shows staff that I can't see regularly or just gives bad light.

I checked all the things that are close to the ground of the pcb and none of them is connected to it accidently. Also I checked all the points and none of the points get electricty (except the ones that need).

What else can I check? (I really have no idea so ANY cluse would be welcomed)

It's unnecessarily complex for what it does.
After all, it's only a Fet version of the Normal Channel on a Twin.
You will end up with something very close to a JC120 or one of the Gxxx Yamahas which in many of their incarnations were basically that.
You might copy one of their preamps to drive any SS power amp.

from looking on the jc120 schematic it looks much more complex than the FET TWIN.  BTW which chipamp do you recommend for the 50-100Watt range (so it would be enough for gigs and rehaursals but also not too loud for home use)
