The sound of this amp is special. It is not for metal and it is not quite for blues but it is to create new
music with a lot of colors to let your dreams become true. I usually modify my amps but this one I didn't much. Just basic. All my amps I wire in the way to get read of parasitic HF oscillations. CT of high voltage supply I wire to chasy and than I take minus from the other point of chasy which is used as a choke to suppress high parasitic frequencies. The cathodes of output tubes I wire strait to chasy to get softer and more playable sound. I recommend this amp as one in collection.
