PepTone Electronics is about making pedals better or making pedals that have not been made, either way we are about putting something out that you cannot already buy. This is why I have not started making any delays. There are so many great delay pedals out there.
One of my favorite all time general delay is an analog delay; The MXR Carbon Copy. Out of all the boutique and common company delay pedals that stands on its own with pure delay tone and done so without tone loss! Now if you are looking for weird spacey looped effects this pedal does not do well, this one is great for just pure analog delay with great control and tone. Yes, the delay does have a tone and the Carbon Copy has such a natural sounding repeat.
As far as digital delays go I can never go wrong with the Boss DD series. There are small differences in the tones of those pedals. From the DD-3 to the DD-7 they offer different settings but also have different qualities in tone on the repeats...the DD-3 seems the most "harsh" with my favorite being the DD-5 that I modified to add warmth.
There are great delays out there but it really depends on what you are really looking for in a delay. You can go all out with the Keeley modulation control Ibanez AD-9 delay setup and spends hundreds of dollars, but many will not need that type of control for delay. I am not one to need constant control of the repeats and delay time to need that but I guess someone needs it.
If you do want something more versatile I would look to the BBE Two Timer pedal that offers one delay pedal with two switches to go back and forth between two delay times. So if you use delay as a slap back and need a specific delay time this pedal would be great because you can get two settings ready to go. The BBE Two Timer does have great sounding delay and won't break the bank either. I just never see a situation where spending $200 + on delay is necessary when there are just as good if not better sounding delays for cheaper. Now if it has a gizmo on it (like the keeley) then go for it if you need it. If you just want a delay that sounds good then I wouldn't go too far. Delay is important but it does not change drastically like boost or overdrive pedals.
There are many delays out there and they are great tools for getting good tone.
