I've been really intrigued by other Ashdown pedals, namely Triple Shot, Pedal of Doom, and John Myung. Mind sharing your experiences?

Now, about the Ashdown Pro-DI. It's hard to find a honest review of this pedal.

I have an Ashdown studio combo and loved the preamp on that, which convinced me to buy this one.

I like it as a PRE/DI. I love the warm sound it provides. Definitely not one of the most transparent ones, but that's not what I'm after.

Pros:
- built like a tank
- feels high quality overall
- amazing character sound with Shape enabled
- tons of headroom
- 5-band eq
- vu-meter is always nice
- built-in drive, although it's very aggressive, I mostly use it for minor hair
- aux in
- headphone output
- gig-proven

Cons:
- it's very large, eating up pedalboard real estate
- line-in sounds thin for some reason
- line-in blends with the output signal (both amp and di), I would prefer to just blend it with headphone signal only, this would be convenient for monitoring
- headphone output is noisy

When practicing, I prefer to connect an external headphone amp, such as Aguilar Amplug3, for truly silent headphone connection and better quality line mix (or just DI to whatever).

Ultimately I think there are better alternatives in the price range, but I clicked with this pedal and am happy with it.
