Runoffgroove Ginger - bass loss?

[spacecadetcharlie]

Apologies if this is the wrong forum...

I have a Runoffgroove Ginger for bass - great edge of grit sound, love the boost it gives, but for some reason I notice a significant loss of deep bass frequencies when I kick it on (compared with clean signal into my amp). So, I am looking at the schematic, wondering if there's a gatekeeper somewhere, or if there is any simple mod I can do to pass more of that deep bass through:



Looking at the schematic, I'm not sure where I'm losing out on low bass... I thought, maybe the coupling caps (the 220n caps) are a bit too small and thus are ever so slightly rolling off low bass?

Any ideas?

If I were going to guess I would try replacing all three of the 220nf caps with 1uf caps just to see.

I figured I’d probably start with the final 220n (right before the A100k out) and work backwards… thanks

Also curious whether I’m missing something obvious that an experienced eye would catch.
