Barber direct drive mod

[Rock Glenn]

Love the sound of the compact direct drive I built on this site, but I feel like it could use a slight increase in bass frequencies to warrant a spot on my main board. It just lacks a chunkiness when palm muting and hitting dead strings. I can see two possible spots in the circuit to mess with cap values but I'd love an open interpretation on letting just a touch more bass slip through. A little help, friends?
