Not a valve or a tube! Our ValveTubeGuitarAmps Mug. It is thermionic though as it is for drinking your coffee or tea while you contemplate your next riff or challenging amp repair. These are a limited edition and of course these are not tested on our AVO testers.
We can therefore guarantee that they are not compatible with any amp make or model.
It is not recommended that when in use they are not sat on top of your amp. While it will keep your drink warm, the spillage could seriuusly damage your amp and your wealth.
Price includes UK 2nd class postage.
