My Marshall is no longer running the boost channel. Everything works perfectly, the clean channel and the overdrive are working perfectly, but when I turn on the boost channel the overdrive does not emit sound, it loses the full volume. I do not know what to do to solve the problem. I'm in Brazil and I do not know if there is technical assistance here.
Thank you for your message, you will need to contact ProShows as they are the distributor for Brazil
Kind Regards
