This was from the September 1979 issue of ''Practical Electronics''
I built this in 1986, initially with a Veroboard and a plastic box.
A guitar luthier in a local part-time amateur band, who actually
made his own Ibanez Musician-type guitar, later made a couple
more for himself and his second lead, and made a nice aluminium
box for me as well.
R7 can be replaced with 100K variable resistor pot as the
The effect still tended to be a little fuzzy, so R5 may be reduced
to 200k for a gain of just 50, and C5 and C6 could be increased to
680 - 820 pf to filter off a bit more of the high frequencies.
This guy built one.

That issue of Practical Electronics also featured a project for a six channel mixer,
so it might be a good idea to get the old magazine as well.
