I remember these from my 70's "in a band" era, being the techy I had to fix it all. The tape loops came in a nice box, much to the joy of our lead guitarist (who used the Copycat). I kept the old boxes and 'refilled' them with any old bit of tape spliced together, same result. |

Re: WEM Copicat Custom
Is the contact in the footswitch a make or break type?

Re: WEM Copicat Custom
Correct, shorting the wires switches off the effect. I repair & refurbish Copicats of all marks, whoever told you to join the two was grossly incorrect.

Re: WEM Copicat Custom
I third that, when the footswitch is closed (wires twisted together) it sends the play head signals to ground.
Interesting point made on page 10 (Omegaman I think?) that it was possibly modified to use as an overdrive; this obviously being a good example of how confusing these kinds of modifications can make future repairs. This R11 (actually didn't even know its number) sticking up (and a jumper wire touching it) was the first thing I noticed, and all the time the idea that it was just incorrect wiring was bugging me...however I would've been too scared to blow up more caps etc to have tried rewiring it, plus variations in schematics adding to my uncertainty. Then again the quirky nature of these copicats is why they became so popular, it was almost the engineering flaws which gave them their unique sound. No disrespect to Charlie Watkins but in an interview I watched recently he does come across as a charming used-car salesman almost Benny Hill-like character (!) Making the drawing was a great suggestion, otherwise I fear it might have dragged on longer... then again my friend got some new caps in the process which should extend its lifespan. Seriously, thanks for solving this, and echoed drumrolls for being so patient, observant, and helpful! |

Re: WEM Copicat Custom
If whoever did the mods had just scribbled some information on a scrap of paper and put it inside, it could have saved a lot of head scratching!

Re: WEM Copicat Custom
Glad to hear it works.
Thanks for giving me something useful to do whilst sitting in this hotel room in Ohio USA, hence the odd posting time... |

If I were to do any mods, not to this one but perhaps a transistor one, it would be to add more heads, and a variable speed DC motor, or movable heads... |

Re: WEM Copicat Custom
Back in the 70's I used to use a Mk2 copicat not only as an echo, but as an overdrive into a 100W Marshall - ever so good it sounded too
Also used it to lively up our band home recordings, not only for overdrive but the impedance of the 'cat' was a better match for our guitars into the Akai and Sony recorders we were using. Well done to PLJ and Howard for the diagnosis! |
