my question is, why can´t i boost the whole frequency spectrum?
or is this typical for a tube?
i want to use it mainly for drum, synth and bass sounds

when i use only the preamp (no low and hi cuts, tone at 10), i can see in my analyzer cuts at approx. 160Hz and 1200Hz.
my improvements/wishes are:

1. not to fix the HI CUT at 8kHz
2. bypass button for the eq section
my praise for you, NICE SOUND. i like it for example of Pianos
