I’ll preface this by saying I live in an apartment. I recently bought a Phase 90. I love Waylon tones and have always wanted one. It worked great, for about a month. Now I get volume spikes-anywhere from noticeable to holy crap what was that volume spikes. This happened no matter where in the pedal order I put it-first, last, middle, or all by itself. A “R-28” mod was mentioned a few times when I googled this. Unacceptable for a new pedal to me. I called MXR, guy says never heard of it. On the phone he played with theirs and of course, theirs works great. He said nothing to fix. Hmmm. So, I open it up. Seems extremely cheaply made. Are these new pedals just cheap knockoffs of themselves? The pedal is pretty useless to me. Should I look for an older, better made one? Or ???? Anyone else experience this? Thanks!
