Hello,
I own an old Studio .22+ (with graphic EQ). The amp started producing very bad distortion in the Clean channel (only one I use). The sound was similar to a bad tube As the tubes haven't been replaced for a long time I ordered quality tubes from Doug's tubes (matched and proposed for the specific amp) and replaced the tubes. However the problem remained and is characterized mostly by the following:
- In very low levels clean sounds relatively ok
- As gain gets over 2 and master gets higher the amp sounds harsh, produces ugly distorion and hisses very much in some notes/frequencies (bass A among others).
- Bass responce is completely flubby and sounds as if I am using a fuzz box. Only I am not.
- At higher level the whole sound is distorted in a very bad way in the Clean channel, practically there is no clean channel
- When the Master is topped at 10, the level is still low to use with the band and the quality is unacceptable, while before I always kept it at 6-7 and was fine.
has anybody had any similar problems or knows anything about that? I am frustrated because this was to be my main amp for some gigs now and local techs (live in Barcelona-Spain) have a waiting time of a month to check it.
thanks guys..
