I need to build an easy project (in a 1590A, so not that easy! ;D ) and I thought of a buffer/booster for the start of my chain. Has anyone built something like this? The only project that I found is the AMZ Mosfet Booster, the one with the two outputs. But I don't have the parts for it. However, I have the parts for a Crackle Not Okay (Soulsonic's SHO workalike) and I have already built one which I quite liked! And thought I would maybe throw in a vero Klon buffer (switchable ON/OFF), and get done with it.
Any suggestions?

The Fatpants 2013 has a buffered bypass option and fits in a 1590A. It's a very good 18V FET buffer and a great sounding preamp when on.
Although I love the AMZ Mosfet booster as a boost, MOSFETs make poor buffers. There's a lot of treble loss despite the good input impedance characteristics, and the drain biasing limits the total headroom. There's really no advantage to doing that ... you can make a separate FET buffer for the bypass with a mere four parts. Plus anything you do to switch the same transistor to buffered bypass output will create horrendous switch pops.
The Klon's buffer is a textbook op amp buffer. There's nothing special about it; it's not even optimal.
The Beauty Booster I sell sounds perfect for you. It's a buffer, with a switchable boost function. The buffer is always on, but when you want some Boost you stomp that switch. It can get quite loud, and it's designed to be a pure clean boost, no colouring the signal.

Guys! First of all, thank you so much for your replies! :)
I had nothing to do, and I finally went and built a 1590A Crackle Not Okay (had the board already populated) with a switchable ON/OFF buffer using a 1776 Effects' (Thank you Josh! :D ) future project. ;)
REALLY awesome sounding combo! And a great tool for my pedalboard!
I'll post a build report in a couple of days! :)

Interesting. How would one go about making it "optimal"... other than ditching it an using an entirely different circuit?
