Re: Volume control issue / Trainwreck Express

Thank you for enlighten me! Everything you said couldn’t have been explained better and makes perfectly sense! Applying this logic to the original grounding scheme there are many grounding loops inside an express. There is a ground loop as soon as you decide to install a third grounding spot. Hopefu...

Re: Volume control issue / Trainwreck Express

Thanks Mark, I’ll do it like that in future, too. :lol: Why is this considered to be bad grounding technique? Contrary to the overall grounding in an original Express (which I have chosen as well) I thought of a (copper) bus grounding following the signal path being a good solution. It‘s possible to...

Re: Volume control issue / Trainwreck Express

I ended up with a new CTS 450T - 1Meg (the ones with solid brass shaft from mojotone). I really like the taper on that ones. I selected one with 7% taper, the other one I ordered has 8% taper. Maybe it was not a faulty potentiometer from the beginning. Possible I cooked it when I tried to solder on ...

Re: Volume control issue / Trainwreck Express

Thank you all! I ordered two new potentiometers now (for treble and volume) just for the case both are faulty components or one of the ordered ones is faulty as well. Actually my supplier informed me CTS had some trouble with the tolerances of the 1Meg potentiometers. That’s why he didn’t sell them ...

Re: Volume control issue / Trainwreck Express

Thank you for your reply! :) Actually my Express behaves exactly like described in Glen‘s video and it sounds fantastic. But a volume pot behaving like a switch at one point doesn’t seem right to me. It’s like pushing a distortion channel switch on a „normal“ amplifier. The guitar volume doesn’t inf...

Volume control issue / Trainwreck Express

Hey! Finished my express build and absolutely love it! But there’s an issue with the volume control. It’s a CTS 450T with 10% taper. But it actually behaves like a switch on one point. Until maybe 10 o’Clock the volume increases like expected, if you turn it a little (and it’s really impossible to f...
