I miss the one that I had, and gave away to one of my troops that was learning guitar. If was stolen shortly thereafter. Now looking back and reading this thread, the nostalgia is hitting me hard. But the world has continued turning for some time since we lost the 15r and I have to ask myself: Could the 15r still hold its place against amps like the Boss Katana 50? I got a used K50 for $150 and I’d love to hear it head to head with the 15r. Any have any experience with both amps side by side?
