HT-DUAL modifications ???

[sir riff a lot]

Hey everyone,

Ive got a HT-Dual which I love , channel one with the crunch button on is one the best rhythm crunch tones Ive found anywhere.
My problem is once I dial in the sound I like on Channel 1 , Channel 2 is always way too bassy.
Does anyone know of any mods to reduce the bass on Channel 2 , can I swap a diode or cap or what ever for a different value ?

Thoughts ??

Just an update on this , no-one could advise a way to mod this pedal.
Ive worked around it by dialing in ch2 as my main crunch sound now , and using ch1 as a slightly dirty sound.

Ive also tried a couple of different 12ax7 tubes in it , but in the end the stock sovtek tube sounded best to my ears.
