My Egnater Rebel was ticking along just fine as the gritty dry undercurrent behind my AC30 with the wet sound from my pedalboard. Then, on a whim i started playing a dynasonic jet through it And it sounded AWFUL. Metallic, harsh, tinny, shrill, unlistenable. I bought it used in June so i wondered if the tubes were shot. Tried the “tap them with a pencil” test on the power tubes and switched them all out..... but now its dead as a doornail. Silent. Only the power light works. And the tubes glow. Silently. Fuse? Can it be anything else? And the awful tinny sound.... preamp tubes? Cant see me putting a lot of money into having this fixed. Its going to cost about $150 for tubes.
