Thanks!
I agree, they're almost too fat for me as well. The Marsh circuit one is the one I reverse engineered and put in my Bogner 2204. It's still in Germany, but I'm getting it shipped to the UK soon. That circuit is definitely my favorite Bogner circuit so far.
I honestly got pretty obsessed with these old Bogner mods and am always looking for them online. There's one on Reverb, but it's just way too expensive for me right now, even after I've sold my Gower Jose.
Loving your recent posts of these modded Bogners and your take on the circuit. Thanks for sharing Eddy, keep them coming. Any ideas how different Bogners mods are in comparison to some of his amps? Similar preamp designs or just completely different?
