Guitar preamp

[Hypnotize]

Hi there,

I'm quiet new to world of electronics , so i need your help
I have 20w poweramp (that is using tda2005r ic)
I would like to make a simple practice amp for my friend from it .And now the problem is that I don't know which preamp would do the trick . I have made "tillman preamp" but it is pretty quiet when playing .
Which preamp should I make in order to make it work with that pow.amp ?
Thanks a lot

I have the parts laying on my table for this one right now for use as a preamp:

I have also used the Fetzer Valve (also from runoffgroove) with success.

You could also try the Alembic FET2B, a FET version of the F2B (I think was the name).

You could try the lab series ch1 preamp.
