Re: My Dumble hrm needs help . Please.

Re: My Dumble hrm needs help . Please.

Re: My Dumble hrm needs help . Please.

I never have a chance to play at another ceriatone dumble hrm so it's very hard justified how this amp should sound . Maybe i was expecting too much from it. O...

My Dumble hrm needs help . Please.
Where to start. It's been a long journey with my amplifier. At start it was built with a 6 l 6, few months ago l change it to el34. My problem is that i feel there's no overdrive in this amplifier. All switches are solder and wired properly i check this 20 times. All voltages are correct. But amplif...
