Hi, i want to make my own solid state amp from preamp and poweramp chip and i want to make some good preamp with tonecontrols. I tried BJT designs, jfet preamp emulators , even opamp based but nothing sounds like i want it to... jfets sounded best but the ones i have are too powerfull, when i bias them to 1/2 of PS i cant get clean tone. Sound im looking for is clean, with gain maxed little bit dirty but not too much, maybe 2 gain stages, classic tonestack and what i can clean up with turnign volume down on guitar. Any ideas? I tried Alembic Fet2B, i liked it most, but i had to omit 47uF bypass caps parallel to resistors because i got overdrive not clean sound. There is how i would like it to sound (intro) https://youtu.be/Dhfy9TPga-c
