I don’t think so, I’ve seen several people standing on one at once. Perhaps worth an email to Eich but I’d be surprised. I have a fairly heavy chair on mine.
Well worth calling Watford Valves. I use them a lot in the past and they are always really helpful and interesting to talk to.
When it does to pre-amp valves, I'd be tempted to buy a few and try them out.
Here’s one on the back of my headstock and here’s one on my mini bass. Stuck with 3M double sided tape but on mini bass I may adapt the clip attached to the back of the tuner to attach it permanently also so that it swivels outwards for batt replacement.
I remove the clip from the polytune and attach it to my bass permanently. Always interested to hear about other tuners but many have uneven surfaces on the back so it can’t be stuck to me bayzz
You could do some basic editing in terms of snipping off the beginning and end but I wouldn’t worry doing more than that. And yes once uploaded you just put the link here.
If you've enabled desktop notifications (for example if someone replies to thread you have open but you're in anther tab) that may have an impact on your browser, so maybe try turning those off.
Well in terms of uploading to here, just drag and drop the file into the attachment system.
You might prefer to upload a video to YouTube or an audio track to SoundCloud though depending on your preference.
