Be careful, I own Dumkudo, SOV-2 (what Robben Ford and Matt Schofield use), Klon and a bunch more - point, no D-style pedal provides D-tone, only a D-style amp. These pedals are just sprinkles on your guitar and amp tone, not the creater of tone IMO. I use D-style amps, but have tried these pedals in non D-style amps with no sucess.
In regards to Dumkudo, its a nice pedal, but at $325.00, it has flaw.
1. Again, no pedal gets you D-style amp tone or those amps would not exist, we all would have cheap tube amps and buy d-style pedals.....oh, then D-style pedals would cost $2,000 or more...lol
2. Dumkudo pedal volume control boosts volume way to fast/early, you literally can't get volume past 9'o clock all while still mixing well in volume from clean channel on amp - flaw.
SOV-2 I have, used by Ford, etc, but doesn't proviode d-style tone again, but a great pedal if you don't want to change your amp to guitar tone, so in this case, you don't want this pedal, as you want to change your amp tone to be something it's not - D-style amp.
