thanks guys and especially Glen, so far I bought this custom artist both volume and boutique amp vol 1, I don't have much time to tweak now due to family and job commitment, so it's huge help for me to get some specific tone done and bring to rehearsal, I'm in cover band where we do all kind of classic rock from 70 to 90s , so need wide range of tonality.
I'm still looking for FRFR solutions...
