This was from the September 1979 issue of ''Practical Electronics''
magazine.
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
Distortion control.
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.

- my favorite amplifier: Hartke KM-50, for my Mellotron!
- Completed builds: None - so far, despite having a huge amount of components. I've just started building 3 (yes, three) Reverb units that use a PT2399! 3? Yes - one for my Mellotron a 2 for musician friends of mine in Stafford, England. One is a self-trained guitarist and the other is a keyboard whizz!

...and the units keep on coming!!! This is from the September 1979 issue of British publication "Practical Electronics". It's different from the published article, as I generally tend to simplify things by leaving out the battery switching circuitry based around the contacts of special jack-sockets. I usually have a 3P2W toggle switch that bypasses the effect and switches the battery on & off.
I don't have anything to say, so I won't say it!
Thanks for sharing this!
