Tonebender MkI More Bass

[Mcentee2]

Have a Tonebender MkI that currently has standard cap values in, from input to output:

0.01uF input
25uF between Q1 and Q2
0.1uF between Q2 and Q3
0.1uF Output

Although it probably is a "true" TB MkI sound, it is a little thin for me - what is the easiest way to get more bass from it ?

Do I need to tweak all the caps larger, or will just one of them do the trick ?

Hard to say without schematic..

Supposing series configuration for all caps, you have to deal with respective resistors (impedances) to find out their individual HPF cut-off frequencies, lower the higher of them and check for possible "overlap" with the closer unaltered..

This is the "standard" TB Mk I here that I have  seen on a few posts so far in DIYSB  threads:

Just tried some caps out - anything more than the 0.1uF does add more bass progressively.

1uF seems a sweet spot, at 10uF however starting to hear creeping in a "capacitor charging delay" after heavy chords. The cap seems to be "used up" then take up to half a second or so to recharge and start passing signal again - quiet then normal hiss creeps back in.
