Hey all, I have a Variax 300 given to me by my friend who was no longer using it. Came without a power supply and it drained batteries super quickly so I bought a second hand XPS Mini to power it. I've been using it for a week now and it works, however, I find that when I select some of the guitar 'types' the sound comes out glitchy. If I let a note play out it'll warp (sort of turning off and on again but in a strange way). Curiously this only seems to happen on the t-model, spank, lester and occasionally special modes. Anyone have any experience or advice for this? I can play without them but it cuts down the functionality of the guitar. I do not have access to a USB interface so flashing is not currently possible.
