I am new to this forum, but much like all of you I too am a SUNN fan. I recently bought a SUNN Model T reissue and noticed when I go from the clean channel to the gain channel it is considerably quieter. I have heard that some amps have a limiter that will do this. Is this true and if so is there any way I could remove this with out damaging the amp, or should I try different tubes. thanks in advance.
