Re: D.S. Gibbs & I.M. Shaw, Tone Booster, in: Everyday Electronics, Sept. 1978 🇬🇧

I really dig this circuit. Thanks a bunch for sharing. Really works in tandem with SG and Princeton. 🤙 There are so many tried and tested circuit to build that I wouldn't think people would try these... but thanks for your feedback -- I take it the circuit worked as drawn? That's never a given in t...

Re: Hornby Skewes - Zonk Machine / Zonk II ( JHS ) [schematic]

I have an original Zonk II that I bought back in the 70s. It quit working some time ago and the repair guy said a transistor was blown. He said he couldn't fix it. Does anyone know anything about these things? Hi, welcome to the forum. We are always interested in gut shot pictures of original units...

Re: Davoli Krundaal - Amplificatore D531T [schematic]

https://youtu.be/W-4TO4SocJg?si=rm974Ae5Yg3grZEM When I came across that first, pink one, I thought a lot of work had been done to the amp, considering the haphazard way in which the components were attached. There are capacitor holes in the chassis, but they were not used in this built. Anyway, loo...

Re: Boss CE1 clone no chorus [documentation]

Hi there, Looks very impressive, but first question is always: What layout and schematic did you built off? Is the layout verified? Did you use correct(ly oriented) components? Are the chips good? Below under similar topics you'll find some threads on the CE2, but not much on the CE1... I don't thin...

Well, I think that's quite enough -- Ron is a forum member too, but really has a proper job - quite technical. I'm sure he'll get back to you, but I'm honestly surprised he even took on the job - he probably didn't read this thread... After all the advice given in this thread and not heeded, there i...

Re: Harmonic Generator

GP Electronics come up quite regularly during the 1970s in Beat Instrumental , and even in the mid-60s, the pedals were being sold out of London (which is on the complete opposite side of the country from Devon). https://www.worldradiohistory.com/Beat-Instrumental-UK.htm Gerry Pope or GP/G.P.

Re: Harmonic Generator

@matthewnorthmusic -- thanks so much for chiming in! What I don't understand is -- why hasn't anyone spoken to Gerry Pope in person yet? And if somebody does, please use a voice recorder or film the interview. The amps are clearly very much legit -- but do look very 70s to me. For now, with no unit ...
