Supreaux Question (Bass response)

[rody82]

Hi! Its my first post  

My Supreaux is a bit fuzzy on the bass notes.  Annoying buzz when picking strings hard, but the high notes are almost perfect.
I've tried it with humbuckers/single coils, 2 guitars..  same results. Even with low gain settings it can be heard, but a bit more subtle..
Transistor voltages are all at about 4.3V
I've built it on perfboard, and PCB too, they sound the same.
Maybe my amp? (Roland Cube30) Or Guitars (Yamaha Pacifica 604W, Ibanez S470, both with stock pickups...)

Any mods to cure this?

Thank you!

Same with me , everything you said. I have two Dimarzio PAF type fat humbuckers with split coil switch.
Split or full pickups, way too muddy and  fuzzy on low E and A strings. On upper strings beautiful, clear, trebly but in a good way, warm overdiven sounds. I'll mess a bit with coupling caps, if I find a solution, I'll post it here.

Change the two leftmost 4n7 caps to 2n2. That should give more clarity to bass frequencies. If the sound becomes too thin, try with 3n3; if still too much bass, go down to 1n5. I would suggest changing both capacitors in tandem.

Cheers.
