The delays you're asking for are a dime a dozen. It would be much harder to find a delay that did kill your tone.
Yes. Pretty much all digital delays and ones with a dry-through will work.
I know I'll get flamed for this, but in my experience, delay tone loss in a myth. I added a series loop to my JTM build and it still gushes tone, even with a TC Flashback X4.
I wont flame you, I converted to the loop side too. Especially playing higher gain stuff, it just works.
Try a Boss DD-3.
Good call. the dd3 should be everyone's first delay. It's one of those ones that everyone always comes back to, like a comfortable hoodie.
Run your delay through the loop with a lehle parallel, this will make most delays sound considerably better.
Also a great suggestion. Lehle stuff is spendy but worth it IME.
My suggestion would be Deep Blue Delay. Analog dry thru is essential. Keep the mix low as others have mentioned.
If the Mad Professor Deep Blue Delay doesn’t work for you in this respect, nothing will.
This sounds like a delay I need to try
